-## Project Overview
-
-ComfyUI-KikoTools is a planned modular collection of custom ComfyUI nodes that will provide essential tools missing from the standard ComfyUI release. All nodes will be grouped under "ComfyAssets" in the ComfyUI interface. The project is designed for extensibility, allowing new tools to be added easily while maintaining clean separation of concerns.
-
-**Current Status**: Project is in initial planning phase. Only documentation and licensing files exist.
-
-## Architecture
-
-### Design Principles
-- **Modular Design**: Each tool is a separate, self-contained module
-- **ComfyAssets Grouping**: All nodes appear under the "ComfyAssets" category
-- **Test-Driven Development**: Every tool includes comprehensive tests
-- **Clean Interfaces**: Standardized input/output patterns across tools
-
-### Core Components
-- **Tool Registry**: Central registration system for all KikoTools nodes
-- **Base Classes**: Shared functionality for consistent tool behavior
-- **Individual Tools**: Self-contained modules for specific functionality
-
-### Current Tools
-
-#### 1. Resolution Calculator (First Tool)
-- **Purpose**: Calculate upscale resolution from image or latent inputs
-- **Inputs**: 
-  - Image or Latent tensor
-  - Scale factor (1, 2, 3, 1.2, 1.5, 2.0)
-- **Outputs**: 
-  - Width (INT)
-  - Height (INT)
-- **Target Models**: Flux and SDXL optimized
-- **Use Case**: Connect calculated dimensions to upscaler nodes
-
-## Technology Stack
-
-- **Backend**: Python with ComfyUI node patterns
-- **Node Framework**: ComfyUI INPUT_TYPES, RETURN_TYPES, execute() patterns
-- **Testing**: pytest with ComfyUI test fixtures
-- **Code Quality**: black, flake8, mypy
-- **Integration**: ComfyUI execution queue and tensor systems
-

-## Key ComfyUI Integration Points
-
-### Node Registration Pattern
-```python
-# Each tool follows this pattern in kikotools/tools/{tool_name}/node.py
-class ResolutionCalculatorNode:
-    @classmethod
-    def INPUT_TYPES(cls):
-        return {
-            "required": {
-                "scale_factor": ("FLOAT", {"default": 2.0, "min": 1.0, "max": 8.0, "step": 0.1}),
-            },
-            "optional": {
-                "image": ("IMAGE",),
-                "latent": ("LATENT",),
-            }
-        }
-    
-    RETURN_TYPES = ("INT", "INT")
-    RETURN_NAMES = ("width", "height")
-    FUNCTION = "calculate_resolution"
-    CATEGORY = "ComfyAssets"  # All tools use this category
-    
-    def calculate_resolution(self, scale_factor, image=None, latent=None):
-        # Implementation here
-        pass
-```
-
-### Base Node Class
-- Provides consistent "ComfyAssets" categorization
-- Standardizes error handling and logging
-- Implements common validation patterns
-- Ensures consistent return type handling
-
-### Tool Registry System
-- Automatic discovery of tools in `kikotools/tools/`
-- Dynamic node registration during ComfyUI startup
-- Version compatibility checking
-- Dependency validation
-
-## Test-Driven Development (TDD) Workflow
-
-### 1. Write Tests First
-```python
-# tests/unit/tools/test_resolution_calculator.py
-def test_resolution_calculator_with_image():
-    """Test resolution calculation with image input."""
-    # Arrange
-    node = ResolutionCalculatorNode()
-    test_image = create_test_image(512, 512)  # fixture
-    scale_factor = 2.0
-    
-    # Act
-    width, height = node.calculate_resolution(scale_factor, image=test_image)
-    
-    # Assert
-    assert width == 1024
-    assert height == 1024
-
-def test_resolution_calculator_with_latent():
-    """Test resolution calculation with latent input."""
-    # Similar pattern for latent inputs
-    pass
-```
-
-### 2. Run Tests (Should Fail)
-```bash
-pytest tests/unit/tools/test_resolution_calculator.py -v
-```
-
-### 3. Implement Minimal Code
-```python
-# kikotools/tools/resolution_calculator/logic.py
-def calculate_upscale_resolution(input_tensor, scale_factor):
-    """Calculate new resolution based on input and scale factor."""
-    # Minimal implementation to pass tests
-    pass
-```
-
-### 4. Refactor and Expand
-- Add error handling
-- Optimize for Flux/SDXL specific requirements
-- Add comprehensive validation
-- Implement edge case handling
-
-### 5. Integration Testing
-```python
-# tests/integration/test_workflow_execution.py
-def test_resolution_calculator_in_workflow():
-    """Test resolution calculator in full ComfyUI workflow."""
-    workflow = load_test_workflow("resolution_calculator_example.json")
-    result = execute_comfyui_workflow(workflow)
-    assert result.success
-```
-
-## Tool-Specific Implementation Notes
-
-### Resolution Calculator
-- **Input Validation**: Handle both image and latent tensors
-- **Scale Factors**: Support integer (1, 2, 3) and float (1.2, 1.5, 2.0) multipliers
-- **Model Optimization**: Consider Flux and SDXL specific resolution requirements
-- **Output Format**: Integer width/height suitable for upscaler node connections
-- **Error Handling**: Graceful handling of invalid inputs or edge cases
-
-### Future Tools (Planned)
-- Batch Image Processor
-- Advanced Prompt Utilities
-- Model Management Tools
-- Custom Sampling Methods
-
-## Development Workflow
-
-### Adding a New Tool
-1. **Plan**: Define tool purpose, inputs, outputs, and test cases
-2. **Generate**: Use `python scripts/create_tool.py --name "NewTool"`
-3. **Test**: Write comprehensive tests following TDD principles
-4. **Implement**: Build tool logic with proper ComfyUI integration
-5. **Register**: Add tool to registry and validate registration
-6. **Document**: Update examples and documentation
-7. **Validate**: Test in real ComfyUI environment with actual workflows
-
-### Code Quality Standards
-- **Type Hints**: Full type annotation for all functions
-- **Documentation**: Docstrings for all public methods and classes
-- **Testing**: Minimum 90% test coverage for all tools
-- **Linting**: Pass all flake8 and mypy checks
-- **Formatting**: Auto-formatted with black
-
-### Release Process
-1. Run full test suite: `pytest tests/`
-2. Validate in ComfyUI: `python scripts/validate_nodes.py`
-3. Update version numbers and changelog
-4. Create example workflows demonstrating new features
-5. Update ComfyUI-Manager compatibility metadata
-
-## Critical Implementation Notes
-
-### ComfyUI Compatibility
-- Follow ComfyUI tensor format conventions
-- Implement proper memory management for large tensors
-- Handle ComfyUI execution context correctly
-- Ensure compatibility with ComfyUI's automatic typing system
-
-### Performance Considerations
-- Optimize for real-time workflow execution
-- Minimize memory allocation during processing

+# ComfyUI XYZ Grid Comparison Nodes
+
+## Project Objective
+Create a modular suite of ComfyUI nodes for visual grid-based comparisons across parameters such as:
+
+- Models
+- LoRAs
+- Schedulers
+- Samplers
+- CFG Scale
+- Steps
+- Clip Skip
+- VAEs
+- Flux Guidance (custom model settings)
+
+The tool will support X, Y, and optional Z axis configuration using a polished, intuitive UI with no scripting or coding required.
+
+---
+
+## Design Goals
+
+- **Modular Architecture:** Built as multiple nodes (not monolithic)
+- **Standard Node Compatibility:** Work with *any* KSampler, Model Loader, etc.
+- **User Friendly UI:** Dropdowns, toggles, and visual input—no syntax or scripting
+- **Flexible Axis Mapping:** Any parameter can go on X, Y, or Z
+- **Dynamic Grid Generation:** One-click execution queues all combinations
+- **Labeling:** Automatic overlay and metadata support with clean presentation
+- **High Performance:** Smart resource caching and sequential queuing
+
+---
+
+## Key Nodes
+
+### 1. `XYZ Plot Controller`
+- Main config node
+- Allows axis selection (X, Y, optional Z)
+- Outputs: axis values, labels, grid ID
+- Automatically queues image generation
+
+### 2. `Image Grid Combiner`
+- Accepts image + axis metadata
+- Assembles a labeled grid (or multiple grids)
+- Outputs: grid image(s), optional metadata (label list, value list)
+
+---
+
+## Parameter Types
+Supported as axis values:
+- Model (checkpoint)
+- LoRA (file)
+- VAE
+- Sampler (Euler, DPM++, etc.)
+- Scheduler
+- CFG Scale (float list)
+- Steps (int list)
+- Clip Skip
+- Prompt (swap full prompt or use template)
+- Seed
+- Custom (e.g., Flux guidance strength)
+
+---
+
+## UI Design
+
+### Axis Config (for X, Y, Z)
+- Dropdown: Select parameter type
+- Input: List of values (dynamic UI)
+  - File pickers (models, LoRAs)
+  - Number range or CSV (steps, CFG)
+  - Text input (prompts)
+- Label customization
+  - Prefix: optional (e.g., CFG=, Sampler:)
+  - Label format: full, short, value only
+
+### Execution
+- One-click generate
+- Internally queues all combinations (X * Y * Z)
+- Reuses sampler, model loader, etc.
+- Supports caching to avoid repeated loads
+
+---
+
+## Output Behavior
+- Combiner tracks image count
+- Assembles grid when complete
+- Draws axis labels using PIL
+- Handles Z axis by outputting multiple grids
+- Preview as images come in
+- Metadata export (optional JSON/text)
+
+---
+
+## Example Use Cases
+
+### Model vs CFG
+- X: Models A/B
+- Y: CFG [5,10,15]
+- Output: 2x3 grid with axis labels
+
+### Prompt vs Sampler
+- X: Prompt variations
+- Y: Samplers
+- Output: labeled comparison grid
+
+### LoRA vs Seed, Z=Strength
+- X: LoRA name
+- Y: Seeds
+- Z: LoRA strength
+- Output: Multiple 2D grids, one per Z value
+
+---
+
+## Development Phases
+
+### Phase 1: MVP
+- X/Y support
+- Core image generation loop
+- Grid image stitching
+
+### Phase 2: Z Axis + More Parameters
+- Prompt, LoRA, Flux guidance, etc.
+
+### Phase 3: UI Polish
+- Dynamic widgets
+- Label controls, error handling
+
+### Phase 4: Performance & Optimization
+- Model caching
+- Memory handling
+- Abort/resume logic
+
+### Phase 5: Docs & Examples
+- Example workflows
+- Visual documentation

+# RGThree-Style Dynamic Widget Framework for ComfyUI
+
+This document explains how to implement RGThree's Power Lora Loader-style dynamic widget system in your own ComfyUI nodes. This framework provides a clean UI with toggles, dynamic widget management, and proper persistence across page refreshes.
+
+## Key Features
+
+- **Dynamic widget addition/removal** - Users can add/remove items at runtime
+- **Toggle switches** - Clean circular toggles instead of checkboxes
+- **Strength controls** - Arrow buttons with editable values for fine control
+- **Right-click context menus** - Only on the item name area
+- **Full persistence** - All values persist across page refreshes
+- **Hide/show widgets** - Proper cleanup when switching between types
+
+## Core Implementation Pattern
+
+### 1. Node Setup in JavaScript
+
+```javascript
+app.registerExtension({
+    name: "YourExtension.YourNode",
+    
+    async beforeRegisterNodeDef(nodeType, nodeData, app) {
+        if (nodeData.name === "YourNodeName") {
+            const onNodeCreated = nodeType.prototype.onNodeCreated;
+            
+            nodeType.prototype.onNodeCreated = function() {
+                const node = this;
+                
+                if (onNodeCreated) {
+                    onNodeCreated.apply(this, arguments);
+                }
+                
+                // Enable widget serialization
+                this.serialize_widgets = true;
+                
+                // Track widget visibility
+                this.hiddenWidgets = new Set();
+                
+                // Initialize storage for dynamic widgets
+                if (!node.dynamicWidgets) {
+                    node.dynamicWidgets = {
+                        category1: [],
+                        category2: []
+                    };
+                }
+                
+                // Store references to buttons and text widgets
+                if (!node.addButtons) {
+                    node.addButtons = {};
+                }
+                if (!node.textWidgets) {
+                    node.textWidgets = {};
+                }
+            };
+        }
+    }

+const originalGetSlotInPosition = node.getSlotInPosition;
+node.getSlotInPosition = function(x, y) {
+    const slot = originalGetSlotInPosition ? originalGetSlotInPosition.call(this, x, y) : null;

+### 6. Widget Visibility Management
+
+```javascript
+function updateWidgets(node, category, type, skipClear = false) {
+    // Hide/show widgets instead of removing them
+    if (!skipClear) {
+        // Hide all widgets for this category
+        node.widgets?.forEach(widget => {
+            if (widget.name?.includes(category)) {
+                widget.hidden = true;
+                widget.computeSize = () => [0, 0];
+                node.hiddenWidgets?.add(widget.name);
+            }
+        });
+        
+        // Clear dynamic widgets
+        if (node.dynamicWidgets[category]) {
+            while (node.dynamicWidgets[category].length > 0) {
+                const widget = node.dynamicWidgets[category].pop();
+                const index = node.widgets.indexOf(widget);
+                if (index > -1) {
+                    node.widgets.splice(index, 1);
+                }
+            }
+        }
+    }
+    
+    // Add or unhide widgets based on type
+    if (needsTextWidget(type)) {
+        const widgetName = `${category}_text`;
+        let existingWidget = node.widgets?.find(w => w.name === widgetName);
+        
+        if (!existingWidget) {
+            // Create new widget
+            const textWidget = ComfyWidgets.STRING(node, widgetName, ["STRING", {
+                default: "",
+                multiline: true
+            }]);
+            node.textWidgets[category] = textWidget.widget;
+        } else {
+            // Unhide existing widget
+            existingWidget.hidden = false;
+            existingWidget.computeSize = () => [node.size[0] - 20, LiteGraph.NODE_WIDGET_HEIGHT];
+            node.hiddenWidgets?.delete(existingWidget.name);
+            node.textWidgets[category] = existingWidget;
+        }
+    }
+}
+```
+
+## Best Practices
+
+1. **Always use hide/show instead of remove/add** for text widgets to preserve values
+2. **Track widget state** in dedicated objects (dynamicWidgets, textWidgets, etc.)
+3. **Override serialization** to ensure ComfyUI properly saves widget values
+4. **Use skipClear flags** during restoration to prevent widget clearing
+5. **Implement proper mouse bounds checking** for custom controls
+6. **Store metadata** (_axis, _type) with widget values for easier restoration
+7. **Don't auto-resize nodes** - respect user's manual sizing
+
+## Common Pitfalls to Avoid
+
+1. **Don't remove widgets during configure** - this loses their values
+2. **Don't rely on widget indices** - they can change
+3. **Don't forget to handle inputEl** for text widgets
+4. **Don't create widgets without checking if they exist** first
+5. **Always deep copy values** when serializing to prevent modification
+
+## Testing Checklist
+
+- [ ] Widgets persist across page refresh
+- [ ] Toggle states are maintained
+- [ ] Strength/value controls work with click and drag
+- [ ] Right-click menu only appears on name area
+- [ ] Moving widgets up/down works correctly
+- [ ] Removing widgets works without errors
+- [ ] Switching between types doesn't leave artifacts
+- [ ] All text input types persist (numbers, ranges, prompts)
+- [ ] Hidden widgets don't take up visual space
+- [ ] Widget values serialize correctly in workflow JSON

+
+## Key Implementation Points
+
+1. **Widget Class Design**
+   - Custom widget class with proper value getter/setter
+   - `serializeValue` method for persistence
+   - Complete `draw` and `mouse` methods
+   - Proper bounds tracking for all interactive elements
+
+2. **Node Setup**
+   - `serialize_widgets = true` in onNodeCreated
+   - Tracking objects for dynamic widgets, buttons, and text widgets
+   - Hidden widgets set for visibility management
+
+3. **Configuration Override**
+   - Save widget values before ComfyUI modifies them
+   - Clear tracking objects for fresh restoration
+   - Restore dynamic widgets from saved values
+   - Manually restore text widget values
+

+           "on": true,
+           "name": "euler",
+           "strength": 0.8,
+           "_type": "samplers"
+         }
+       ]
+     }]
+   }
+   ```
+
+2. **Test Checklist**
+   - [ ] Add dynamic widgets with button

+# Display Text
+
+The Display Text node provides advanced text display capabilities with smart formatting, interactive features, and responsive design for ComfyUI workflows.
+
+## Features
+
+- **Smart Prompt Detection**: Automatically detects and formats SDXL-style positive/negative prompt pairs
+- **Text Wrapping**: Proper word wrapping that reflows when node is resized
+- **Scrollable Content**: Mouse wheel scrolling for long texts with visual indicators
+- **Copy Functionality**: Always-visible copy button with visual feedback
+- **Split View Mode**: Side-by-side display for prompt pairs
+- **Responsive Design**: Content adapts to node resizing
+
+## Inputs
+
+- **text** (STRING): The text to display
+  - Can be a single text block
+  - Can contain "Positive prompt:" and "Negative prompt:" sections for automatic split view
+
+## Outputs
+
+- **text** (STRING): Pass-through of the input text
+
+## Display Modes
+
+### Single Text Mode
+
+When the input is regular text without prompt markers, it displays as a single scrollable text area with:
+- Word wrapping at word boundaries
+- Vertical scrolling for long content
+- Single copy button for the entire text
+
+### Split View Mode
+
+Automatically activated when text contains both "Positive prompt:" and "Negative prompt:" sections:
+- Side-by-side display with 50/50 split
+- Independent scrolling for each section
+- Separate copy buttons for each prompt
+- Labels are stripped when copying (clean prompts)
+
+## Usage Examples
+
+### 1. Display Generated Prompts
+
+```
+Gemini Prompt → Display Text → Copy to workflow
+```
+The node automatically detects SDXL format and shows positive/negative prompts side-by-side.
+
+### 2. Debug Text Processing
+
+```
+Text Processing → Display Text → Further Processing
+```
+View intermediate text processing results with proper formatting.
+
+### 3. Show Long Descriptions
+
+```
+Load Text → Display Text → Review
+```
+Display long text content with scrolling and word wrapping.
+
+## Interactive Features
+
+### Copy Button
+- Always visible in the top-right corner
+- Shows "✓ Copied!" feedback on click
+- In split view: separate buttons for each section
+- Strips prompt labels for clean copying
+
+### Scrolling
+- Mouse wheel scrolling when hovering over text
+- Visual indicators appear when content is scrollable
+- Smooth scrolling with proper boundaries
+- Independent scrolling in split view mode
+
+### Resizing
+- Text reflows when node width changes
+- Maintains readability at different sizes
+- Split view maintains 50/50 proportions
+- Minimum height ensures usability
+
+## Smart Prompt Detection
+
+The node intelligently detects prompt formats:
+
+1. **SDXL Format**: 
+   - Looks for "Positive prompt:" and "Negative prompt:" markers
+   - Case-insensitive detection
+   - Handles various formatting styles
+
+2. **Label Stripping**:
+   - When copying from split view, labels are removed
+   - "Positive prompt: beautiful sunset" → "beautiful sunset"
+   - Clean prompts ready for direct use
+
+## Styling
+
+- **Font**: Monospace for consistent alignment
+- **Colors**: 
+  - Text: Light gray (#ddd) on dark background
+  - Background: Semi-transparent dark (#1a1a1a)
+  - Borders: Subtle gray (#333)
+- **Spacing**: Comfortable padding and line height
+- **Visual Feedback**: Hover effects on interactive elements
+
+## Use Cases
+
+### Prompt Engineering Workflows
+- Display AI-generated prompts with proper formatting
+- Compare positive and negative prompts side-by-side
+- Copy refined prompts without manual cleanup
+
+### Text Processing Pipelines
+- Debug text transformations at each step
+- View formatted outputs from text nodes
+- Monitor prompt construction workflows
+
+### Documentation and Notes
+- Display workflow instructions

+- **Memory Efficient**: Only renders visible text portions
+
+## Tips
+
+1. **For Long Prompts**: The scrolling feature handles texts of any length efficiently
+2. **Quick Copy**: Use the copy buttons to quickly grab prompts for other nodes
+3. **Resizing**: Drag node edges to find optimal display width for your content
+4. **Split View**: Works best with SDXL-format prompts but handles any dual-section text
+
+## Integration Example
+
+```
+[Gemini Prompt Engineer] → [Display Text] → [Copy Button Click]
+         ↓                        ↓                    ↓
+   SDXL Format            Split View Display    Clean Prompts
+```
+
+This creates a seamless workflow from prompt generation to usage, with the Display Text node providing the visual interface for review and interaction.

+# XYZ Grid Examples
+
+This directory contains example workflows demonstrating the XYZ Grid nodes for ComfyUI.
+
+## Overview
+
+The XYZ Grid system allows you to create parameter comparison grids with any combination of:
+- Models/Checkpoints
+- Samplers
+- Schedulers
+- CFG Scale
+- Steps
+- Clip Skip
+- VAEs
+- LoRAs
+- Prompts
+- Seeds
+- Flux Guidance
+- Denoise strength
+
+## Basic Usage
+
+1. Add an **XYZ Plot Controller** node to your workflow
+2. Configure X and Y axes (and optionally Z for multiple grids)
+3. Connect the appropriate outputs to your generation nodes
+4. Add an **Image Grid Combiner** node
+5. Connect your generated images to the combiner
+6. Run once - the system handles all iterations automatically!
+
+## Node Descriptions
+
+### XYZ Plot Controller
+
+The main configuration node that drives the grid generation.
+
+**Inputs:**
+- `x_axis_type`: Parameter type for X axis (horizontal)
+- `x_values`: Values to iterate over (comma-separated or range syntax)
+- `y_axis_type`: Parameter type for Y axis (vertical)
+- `y_values`: Values to iterate over
+- `z_axis_type`: (Optional) Parameter type for Z axis (multiple grids)
+- `z_values`: Values for Z axis
+- `auto_queue`: Enable automatic execution queuing
+
+**Outputs:**
+- `grid_data`: Configuration data for the combiner
+- `x_string`, `x_int`, `x_float`: Current X value in different types
+- `y_string`, `y_int`, `y_float`: Current Y value in different types
+- `z_string`, `z_int`, `z_float`: Current Z value in different types
+- `batch_id`: Unique identifier for this grid batch
+
+### Image Grid Combiner
+
+Collects generated images and assembles them into labeled grids.
+
+**Inputs:**
+- `images`: Generated images from your workflow
+- `grid_data`: Configuration from XYZ Plot Controller
+- `font_size`: Size of label text (default: 20)
+- `grid_gap`: Pixel gap between images (default: 10)
+- `label_height`: Height of label area (default: 30)
+- `include_labels`: Whether to add labels (default: true)
+
+**Outputs:**
+- `grid_image`: The assembled grid image(s)
+- `grid_info`: Information about the grid
+
+## Value Syntax
+
+### Lists
+Use comma-separated values:
+```
+euler, euler_ancestral, dpm_2, dpm_2_ancestral
+```
+
+### Ranges
+Use colon syntax for numeric ranges:
+```
+5:10:1     # From 5 to 10, step 1 → [5, 6, 7, 8, 9, 10]
+0.5:2:0.5  # From 0.5 to 2, step 0.5 → [0.5, 1.0, 1.5, 2.0]
+10:50:10   # From 10 to 50, step 10 → [10, 20, 30, 40, 50]
+```
+
+### Model/File Selection
+Use the quick-select dropdowns or type filenames:
+```
+model1.safetensors, model2.ckpt, checkpoint_v3.pt
+```
+
+## Connection Examples
+
+### Varying Sampler
+1. Set X axis to "sampler"
+2. Connect `x_string` output to KSampler's `sampler_name` input
+
+### Varying CFG Scale
+1. Set Y axis to "cfg_scale"
+2. Connect `y_float` output to KSampler's `cfg` input
+
+### Varying Model
+1. Set X axis to "model"
+2. Connect `x_string` output to CheckpointLoader's `ckpt_name` input
+
+### Varying Prompt
+1. Set Y axis to "prompt"
+2. Enter different prompts on separate lines in `y_values`
+3. Connect `y_string` output to CLIPTextEncode's `text` input
+
+## Tips and Tricks
+
+1. **Memory Management**: The system includes intelligent model caching. For large grids with multiple models, it will optimize loading order.
+
+2. **Progress Tracking**: Watch the node title for progress updates (e.g., "XYZ Plot Controller [3/12]")
+
+3. **Large Grids**: Be mindful of total image count. The node shows a warning for grids over 100 images.
+
+4. **Z-Axis**: When using Z-axis, you'll get multiple grid images - one for each Z value.
+
+5. **Label Customization**: Use prefixes to clarify labels (e.g., "CFG=" for CFG values)
+
+## Workflow Files
+
+- `basic_model_cfg_grid.json`: Compare 2 models across 3 CFG values
+- `sampler_comparison.json`: Compare all samplers at different step counts
+- `prompt_variations.json`: Test prompt variations across different models
+- `advanced_3d_grid.json`: Use Z-axis for LoRA strength variations
+- `flux_guidance_test.json`: Test Flux-specific parameters
+
+Load these workflows in ComfyUI to see practical examples of the XYZ Grid system in action!

-   - Background elements and environment
-   - Overall composition and framing
-   - Perspective and camera angle
+Include these elements in your description:
+- Main subject with specific details (appearance, clothing, expression, pose)
+- Environment and background details
+- Lighting conditions and atmosphere
+- Artistic style or photographic approach
+- Color palette and mood
+- Technical details if relevant (camera angle, focal length, etc.)
+- Textures and materials
 
-2. **Visual Style & Technique**
-   - Art style (photorealistic, illustration, painting, etc.)
-   - Rendering technique (digital art, oil painting, watercolor, etc.)
-   - Level of detail and texture quality
-   - Any specific artistic influences or movements
+Write in a natural, descriptive style. Use complete sentences that flow together. Be specific and detailed but maintain readability.
 
-3. **Lighting & Atmosphere**
-   - Light sources and direction
-   - Time of day/lighting conditions
-   - Shadows and highlights
-   - Overall mood and atmosphere
+IMPORTANT: Return ONLY the prompt text. No analysis, headers, or additional commentary. Just the natural language description that can be directly used in FLUX.
 
-4. **Colors & Tones**
-   - Color palette and dominant colors
-   - Color temperature (warm/cool)
-   - Contrast and saturation levels
-   - Any color grading or filters
+Example of correct output:
+A close-up portrait of a middle-aged woman with curly red hair and green eyes, wearing a blue silk blouse. She has a warm smile and freckles across her cheeks. The lighting is soft and natural, coming from a window to her left, creating gentle shadows that accentuate her features. The background is softly blurred, showing hints of a cozy bookshelf. The overall mood is warm and inviting, captured in a photorealistic style with shallow depth of field."""

-- Start with the main subject and action
-- Add style and medium descriptors
-- Include lighting and atmosphere details
-- Specify quality markers and technical aspects
-- Use precise, descriptive language
-- Separate concepts with commas
-- Order from most to least important elements
+Your expertise includes:
+- Leveraging community-tested techniques (ComfyUI, A1111, InvokeAI)
+- Applying photographic theory for realism, composition, lighting
+- Following Civitai trend standards and style best practices
+- Mastering Pony Diffusion XL formatting for stylized and anime content

+For SDXL specifically:
+- Use quality boosters: 8k, RAW photo, masterpiece, ultra detailed, cinematic lighting
+- Prioritize realism and artistry
+- Excellent for portraits, landscapes, or cinematic scenes

+Instructions:
+
+Only reply with two fields:
+Positive prompt: (Your positive prompt here)
+Negative prompt: (Your negative prompt here)

+# XYZ Plot Controller - Advanced Implementation
+
+## Overview
+
+This is a complete reimplementation of the XYZ Plot Controller using the Power Lora Loader architecture from rgthree. The implementation provides dynamic widget management with an intuitive interface.
+
+## Key Features
+
+### Dynamic Widget System
+- **"➕ Add [Type]" Buttons**: When you select models, vaes, loras, samplers, or schedulers for an axis, a button appears to add selections
+- **Toggle On/Off**: Each dynamic widget has a checkbox to enable/disable it without removing
+- **Right-Click Menu**: Right-click any dynamic widget to remove or toggle it
+- **Live Count Updates**: Node title shows total image count in real-time
+
+### Supported Axis Types
+- **Models**: Dynamic dropdown widgets with available checkpoints
+- **VAEs**: Dynamic dropdown widgets (includes "Automatic" option)
+- **LoRAs**: Dynamic dropdown widgets (includes "None" option) 
+- **Samplers**: Dynamic dropdown widgets with all sampler options
+- **Schedulers**: Dynamic dropdown widgets with scheduler options
+- **Numeric Parameters**: Text areas with helpful placeholders
+  - CFG Scale
+  - Steps
+  - Seed
+  - Denoise
+  - CLIP Skip
+- **Prompts**: Multi-line text area for prompt variations
+
+### Technical Implementation
+
+#### Python Backend (`xyz_plot_advanced.py`)
+- Uses `FlexibleOptionalInputType` to accept any number of dynamic inputs
+- Processes kwargs to extract widget values in format: `{axis}_{type}_{id}`
+- Each dynamic widget sends: `{ "on": bool, "value": string }`
+
+#### JavaScript Frontend (`xyz_plot_rgthree.js`)
+- Manages dynamic widget creation/removal
+- Custom widget drawing with toggle checkboxes
+- Serialization/deserialization for workflow saving
+- Real-time validation and counting
+
+## Usage
+
+1. Add the "XYZ Plot Controller (Advanced)" node
+2. Select axis types (X, Y, Z)
+3. Click "➕ Add [Type]" to add selections for that axis
+4. Toggle widgets on/off with checkboxes
+5. Right-click widgets for more options
+6. For numeric types, use comma-separated values or ranges (e.g., "5:15:2.5")
+7. For prompts, enter one per line
+
+## Architecture Benefits
+
+- **Clean Separation**: Python handles data, JavaScript handles UI
+- **Flexible Input System**: Can accept unlimited dynamic widgets
+- **Persistent State**: All widget states are saved with the workflow
+- **Intuitive Interface**: Matches Power Lora Loader's proven UX patterns
+- **Performance**: Only processes enabled widgets
+
+## Future Enhancements
+
+- Model/LoRA info display (CivitAI integration)
+- Drag-and-drop reordering
+- Preset management
+- Batch widget operations

+# XYZ Grid Nodes for ComfyUI
+
+Advanced parameter comparison grid generator for ComfyUI with Power Lora Loader-inspired interface.
+
+## Features
+
+### XYZ Plot Controller
+- **Dynamic Multi-Selection**: Native dropdown widgets for selecting multiple models, VAEs, LoRAs, samplers, and schedulers
+- **Smart Widget Management**: Widgets automatically show/hide based on selected axis types
+- **Visual Organization**: Grouped widgets with headers for better organization
+- **Right-Click Context Menu**:
+  - Clear all selections for a specific type
+  - Show image count breakdown
+  - Keyboard shortcuts (Ctrl+Shift+C to clear all)
+- **Real-time Image Count**: Node title shows total images that will be generated
+- **Warning System**: Visual warning when generating over 100 images
+
+### Supported Parameter Types
+- **Models**: Multiple checkpoint selection
+- **VAEs**: Multiple VAE selection with "Automatic" option
+- **LoRAs**: Multiple LoRA selection with "None" option
+- **Samplers**: euler, euler_ancestral, heun, dpm_2, etc.
+- **Schedulers**: normal, karras, exponential, etc.
+- **Numeric Parameters**:
+  - CFG Scale
+  - Steps
+  - Seed
+  - Denoise
+  - CLIP Skip
+  - Support for ranges (e.g., "5:15:2.5" generates 5, 7.5, 10, 12.5, 15)
+- **Prompts**: Multiple prompts (one per line)
+
+### Image Grid Combiner
+- Automatic grid assembly with customizable spacing
+- Smart labeling with parameter values
+- Z-axis support for generating multiple grid pages
+- Font size and label customization options
+
+## Usage
+
+1. Add an XYZ Plot Controller node
+2. Select axis types (X, Y, and optionally Z)
+3. Use the dropdown widgets to select values for each axis
+4. Connect to your workflow (models, samplers, etc.)
+5. Add Image Grid Combiner at the end to create the labeled grid
+
+## Workflow Example
+
+```
+[XYZ Plot Controller] → [Checkpoint Loader] → [Sampling] → [Image Grid Combiner] → [Save Image]
+```
+
+The controller outputs the current iteration values which can be connected to corresponding nodes in your workflow.
+
+## Tips
+
+- Use the right-click menu to quickly clear selections
+- Check the image count in the node title before running
+- For large grids, consider using the Z-axis to split into multiple pages
+- Numeric ranges are more efficient than listing each value
+
+## Implementation Details
+
+The implementation uses a hybrid approach:
+- Python backend with native ComfyUI widget support
+- JavaScript frontend for enhanced UI features
+- Inspired by Power Lora Loader's dynamic widget management
+- Context menus and keyboard shortcuts for power users

+# ComfyUI-KikoTools XYZ Grid Development Plan
+
+## Current Session Context (2025-08-05)
+
+### Working Branch: `feature/xyz-nodes`
+
+### Completed Work
+
+#### 1. XYZ Plot Controller
+- ✅ Implemented dynamic widget management with RGThree-style interface
+- ✅ Added right-click context menus (Toggle, Move Up/Down, Remove)
+- ✅ Fixed text input removal that was leaving DOM elements behind
+- ✅ Added placeholder hints for text inputs
+- ✅ Auto-resize nodes when adding widgets
+- ✅ Removed unwanted "input" connection from node
+- ✅ Fixed image count calculation for step ranges (e.g., "10:50:5")
+- ✅ Added callbacks to update node title with image count
+
+#### 2. XYZ Prompt Node
+- ✅ Created separate node for prompt management
+- ✅ Implemented dynamic prompt set addition/removal
+- ✅ Added include_negative toggle for showing/hiding negative prompts
+- ✅ Added repeat_negative feature (use first negative for all variations)
+- ✅ Fixed spacing issues with protected button containers
+- ✅ Fixed widget values not passing to Python backend (added FlexibleOptionalInputType)
+- ✅ Visual styling: green background for positive, red for negative prompts
+
+#### 3. ImageGridCombiner
+- ✅ Fixed grid_data structure mismatch with controller
+- ✅ Added proper dimensions object (cols, rows, grids_count)
+- ✅ Added axes object with human-readable labels
+- ✅ Created _create_labels method for formatting axis values
+
+### Current Issues
+
+#### 1. XYZ Prompt Widget Restoration Bug
+**Problem**: When refreshing the page, prompts aren't properly restored
+- Negative prompt appears at top with saved value
+- Positive prompts are lost
+- Widget restoration from widgets_values array not working correctly
+
+**Current Fix Attempt**:
+- Modified onConfigure to properly clean up dynamic widgets
+- Added debug logging to trace restoration
+- Using promptData to track number of prompt sets
+- Need to properly handle widgets_values array restoration
+
+#### 2. Pending Tasks (from todo list)
+- Complete queue implementation for actual ComfyUI API integration
+- Remove debug logging from production JavaScript
+- Add validation for invalid axis combinations
+

+
+### Key Technical Patterns
+
+#### Python Node Pattern
+```python
+class FlexibleOptionalInputType(dict):
+    """Accepts dynamic widget values from JavaScript."""
+    def __contains__(self, key):
+        return True
+    def __getitem__(self, key):
+        return ("STRING", {"multiline": True, "forceInput": False})
+
+# In INPUT_TYPES:
+"optional": FlexibleOptionalInputType()
+```
+
+#### JavaScript Widget Creation
+```javascript
+const widget = ComfyWidgets.STRING(
+    this, 
+    widgetName, 
+    ["STRING", config], 
+    app
+).widget;
+```
+
+#### RGThree-style Context Menu
+```javascript
+getSlotInPosition(x, y) {
+    // Return fake slot with widget for context menu
+    const widget = this.findWidgetAtPosition(x, y);
+    if (widget) {
+        return {
+            slot_index: -1,
+            widget: widget
+        };
+    }
+}
+
+getSlotMenuOptions(slot) {
+    if (slot?.widget) {
+        return this.getWidgetMenuOptions(slot.widget);
+    }
+}
+```
+
+### Git Commands for Session Recovery
+
+```bash
+# Switch to working branch
+git checkout feature/xyz-nodes
+
+# Check current status
+git status
+
+# Recent commits
+git log --oneline -10
+
+# Current changes
+git diff
+```
+
+### Testing Instructions
+
+1. Load ComfyUI
+2. Refresh browser (F5)
+3. Add XYZ Prompt node
+4. Add multiple prompts
+5. Save workflow
+6. Refresh page
+7. Check if prompts are restored correctly
+
+### Debug Points
+
+1. Check browser console for debug logs from:
+   - `XYZ Prompt onConfigure`
+   - `XYZ Prompt serialize`
+   - Widget creation logs
+
+2. Monitor Python console for:
+   - `XYZPrompt.process_prompts` kwargs
+   - Grid data structure output
+
+### Next Steps
+
+1. **Fix widget restoration**: 
+   - Properly handle widgets_values array
+   - Ensure widget values are restored in correct order
+   - Test with multiple prompt sets
+
+2. **Clean up debug code**:
+   - Remove console.log statements
+   - Remove print statements in Python
+
+3. **Complete queue manager**:
+   - Implement actual ComfyUI API integration
+   - Handle batch execution properly
+
+4. **Add validation**:
+   - Prevent same parameter on multiple axes
+   - Validate numeric ranges
+   - Check model/VAE/LoRA availability
+
+### Important Notes
+
+- CLAUDE.md is in .gitignore (local only)
+- Main branch is `main` for PRs
+- Test with actual checkpoint files before merging
+- Memory management for large grids needs optimization
+- Performance concerns with many dynamic widgets
+
+### Session Recovery Command
+
+To continue work in new terminal:
+```bash
+cd /home/vito/code/personal/ComfyUI-KikoTools
+git checkout feature/xyz-nodes
+# Check this plan.md for context
+```

+Project Plan: ComfyUI XYZ Grid Comparison Nodes
+Objectives and Requirements
+We aim to develop a suite of XYZ Plot custom nodes for ComfyUI that enable easy grid comparisons across multiple parameters with minimal user effort. The goal is to support varying any combination of Models (checkpoints), LoRAs, Samplers, Schedulers, CFG scales, Steps, Clip skip, VAEs, and even new model-specific parameters like Flux guidance, all in a structured X/Y (and optional Z) grid format. Key requirements include:
+Simple User Experience: Users should not need to write complex syntax or scripts to set up a grid. All configuration should be via clear UI fields (dropdowns, lists, etc.), unlike TinyTerra’s advanced XYPlot which requires manual text syntax for axes
+runcomfy.com
+.
+Polished UI: Nodes should have an intuitive interface with logical organization. The system will automatically handle labeling of rows/columns with parameter values, adjustable font size, prefixes, etc., to produce presentation-ready grids
+github.com
+. No manual image combining or external tools should be needed.
+Flexibility: Support any sampler or model loader node in ComfyUI – users should not be forced to use a custom KSampler as in the Efficiency node pack (which, while powerful, requires using its custom loader & sampler nodes
+reddit.com
+). Our solution will integrate with ComfyUI’s standard nodes so any sampler algorithm or model can be used.
+Comprehensive Parameter Support: Allow plotting virtually “anything vs anything.” This means an X-axis and Y-axis (and optionally Z for a series of grids) can represent a range of values for any parameter in the workflow – e.g. different sampler names, different checkpoint models, numeric values (like steps or CFG), different prompt texts or LoRAs, etc.
+runcomfy.com
+. The system should even allow advanced uses like varying ControlNet strength or performing prompt search-and-replace if possible
+runcomfy.com
+.
+Single-Run Automation: The user should be able to hit “Generate” once and get a complete labeled grid (or set of grids). The nodes will handle queuing or looping internally. Unlike some current solutions that require manually queuing multiple runs and hitting reset (e.g. the QQ XY Grid requires clicking reset and adding prompt jobs equal to the grid size
+github.com
+), our design will automate the iteration over all combinations.
+Analysis of Existing Solutions
+To design the best XYZ plot nodes, we examined the strengths and weaknesses of existing community solutions:
+TinyTerra’s Advanced XY(Z) Plot: This extension provides very powerful and flexible plotting (even Z-axis for multiple grids) and features like search/replace in prompts and appending values
+runcomfy.com
+. However, it relies on a text-based configuration syntax that users must type into a special node
+runcomfy.com
+. For example, one must write out axis blocks like <1:label>\n[node_ID:option='value'] etc., which is powerful but complex for users to author correctly. Its UI is not as straightforward for novices, despite offering auto-complete aids
+runcomfy.com
+. We aim to capture its flexibility (support for many parameter types and even Z-axis) but present it in a friendlier UI with form inputs instead of coding.
+KenjiQQ’s QQ-Nodes (XY Grid Helper & Accumulator): This approach uses nodes to build the grid via lists and accumulation. The XY Grid Helper node takes lists of row and column values and will iterate through each combination, outputting the current row/col value for other nodes
+github.com
+. A separate Accumulator collects images and assembles the final grid, even showing a live preview as images come in
+github.com
+. It supports custom prefixes, font sizes, and grid gaps for annotation
+github.com
+. However, the user must perform some manual steps: for example, clicking reset and manually queuing the correct number of prompts to generate all combinations
+github.com
+. Additionally, because the output row/col values are untyped, one must use extra “Axis To X” converter nodes to plug them into e.g. a model loader or number input
+github.com
+. Pros: clear separation of concerns (list setup, conversion, accumulation) and customizable layout. Cons: Not entirely automated (requires manual queuing) and the multi-node setup (with converters) is a bit cumbersome UI-wise. We plan to improve upon this by automating the iteration loop and reducing the number of fiddly nodes needed.
+Jags’ Efficiency Nodes (XY Plot Script): The Efficiency node pack includes a very convenient X/Y plot capability that is integrated into a modified KSampler. By connecting an XY Plot script node to the custom KSampler, the sampler will generate a grid of images internally
+github.com
+. This solution is seamless to use and fast – it caches models to avoid reload overhead and can vary many things (including checkpoint models, LoRAs, prompts, etc.) with one click
+runcomfy.com
+. It also supports special plot types like prompt substitution and ControlNet toggles
+runcomfy.com
+. Drawback: It forces the use of the “Efficient” Loader & KSampler nodes
+reddit.com
+, meaning a user must swap out their normal nodes and cannot easily use other samplers or future nodes. This tight coupling is “annoying” for some users
+reddit.com
+. Our plan draws inspiration from Efficiency’s one-click ease and feature depth, but will remain agnostic to specific sampler implementations. We won’t require a custom sampler – our nodes will coordinate with the standard ComfyUI nodes (ensuring broad compatibility).
+ShockZ’s Comfy-Easy-Grids: This extension (a.k.a. ComfyRoll) focuses on simplifying grid generation with automation. The Create Image Grid node lets you specify grid dimensions (X and Y size) and then automatically queues the required number of prompts, outputting the current X and Y index for each iteration
+runcomfy.com
+. Paired with a Save Image Grid node (a modified saver), it will accumulate images until the grid is complete and then output a combined image, including optional row/column labels provided via inputs (e.g. String lists)
+runcomfy.com
+. This approach is very user-friendly – you don’t need to manually queue or reset; the node handles looping internally. It also provides utility nodes like FloatList, StringList, and LoRA List to easily supply sequences of values to iterate
+runcomfy.com
+runcomfy.com
+. Pros: True one-click operation and straightforward list-based UI. Cons: Each axis’s values still need to be prepared as list nodes and wired in, and labeling requires manually creating label lists that correspond to the values. There’s no single consolidated UI to choose parameter types and values – it’s still somewhat low-level in that you construct the mechanism with multiple nodes. We intend to build on this by offering a single high-level interface for selecting parameters and values, while likely leveraging a similar under-the-hood approach of automated queuing and image accumulation.
+In summary, existing solutions prove that it’s possible to plot “anything vs anything” in ComfyUI, but each has trade-offs. Our project will combine their best ideas: the flexibility of TinyTerra, the grid customization and labeling of QQ/Comfy-Easy-Grids, and the one-click convenience of Efficiency – all while removing the need for coding or rigid custom node dependencies.
+Proposed Design and Features
+
+1. Node Architecture
+   We will implement the XYZ plotting functionality as two main nodes for clarity and modularity (similar to the Create/Save separation in easy-grids):
+   XYZ Plot Controller Node – This is the primary configuration node where the user chooses what to vary on the X axis, Y axis, and optionally Z axis. It handles generating the sequence of parameter combinations and triggering the image generation for each. Internally, this node will automatically queue the required runs (or otherwise loop through combinations) so that the user only needs to execute once to get all images, much like Create Image Grid does
+   runcomfy.com
+   . This node will output:
+   Index/Value Outputs: For each axis (X, Y, Z) it provides an output that represents the current value for that axis in a given iteration. These outputs can be fed into other nodes in the workflow (e.g., into a checkpoint loader’s model field, into a sampler’s steps or CFG input, into a text concatenation node for prompts, etc.). We will make these outputs type-aware to avoid extra conversion nodes – e.g., X output might be a string type if X is “model name”, or a float if X is a numeric parameter. (If needed, we can internally include conversion logic or expose outputs in multiple types.)
+   Loop Control/Trigger: It may also output a control signal (like a boolean or trigger) indicating when a batch/grid is complete. This can feed into the second node to signal when to finalize the grid image.
+   Grid Combiner (Image Grid Output) Node – This node will collect the images produced from each combination and assemble the final grid image (or images). It functions similarly to QQ’s accumulator or Easy-Grids’ save node, holding onto incoming images until the set is complete
+   github.com
+   . Once all images for one grid are ready, it will output:
+   A composite grid image arranged according to X and Y dimensions, with annotated labels.
+   It will support multiple pages if a Z-axis is used (for example, if Z has 3 values, it could produce 3 grid images – one per Z – or perhaps one big tiled 3D grid, but likely separate images makes more sense). We will likely implement Z as generating multiple grid outputs (perhaps as a list of images or sequential outputs the user can save individually).
+   Additionally, it could provide a UI preview output for convenience, showing progress as images come in (like QQ’s accumulator does in preview mode
+   github.com
+   ).
+   This two-node setup keeps things organized: the Controller focuses on parameter logic, and the Combiner on image assembly and labeling. For basic use, the user would place these two nodes and connect them: the Controller’s image output (from the sampler) goes into the Combiner’s image input, and the Combiner outputs the final grid. We will make sure they sync via the unique batch ID or trigger so that each grid resets properly and doesn’t mix images from different runs (similar to QQ’s unique_id usage to separate batches
+   runcomfy.com
+   runcomfy.com
+   ).
+2. Parameter Selection UI
+   The XYZ Plot Controller node’s UI will be the heart of user interaction. We will design it with dynamic, easy-to-use widgets:
+   Axis Parameter Dropdowns: The node will have sections for X Axis, Y Axis, and Z Axis. For each axis, the user can choose the parameter type from a dropdown menu. For example:
+   None (if they don’t want to use the Z axis at all, they can disable it),
+   Model (Stable Diffusion checkpoint model),
+   Sampler (diffusion sampler algorithm),
+   Scheduler (if applicable, e.g. scheduler type or noise schedule – we will clarify if this is needed or if “sampler” covers it),
+   CFG Scale (classifier guidance scale),
+   Steps (number of diffusion steps),
+   Clip Skip (text encoder skip levels),
+   VAE (decoder to use),
+   LoRA (Low-Rank Adaptation model to apply),
+   Prompt Text (to vary text or prompt components),
+   Flux Guidance (if using a Flux model, vary its guidance strength or related parameter),
+   Seed (to test different random seeds),
+   etc. – Essentially any parameter that a ComfyUI workflow might want to sweep. We can start with the most common ones and allow extending in future.
+   Value Input Fields: Depending on the parameter chosen, the UI will present an appropriate input mechanism for the list of values:
+   For categorical choices (Model, Sampler, VAE, LoRA), we will provide either a multi-select checklist or a list builder. Ideally, we can query the available options dynamically:
+   Model: Provide a dropdown or list of available checkpoint files in the models folder, so the user can select multiple models to compare. (We will use ComfyUI’s existing model loader API or search the directory for model filenames).
+   Sampler: A list of sampler names (Euler, Euler a, LMS, DPM++ etc.) – we can fetch these from ComfyUI’s KSampler options or maintain a predefined list if needed.
+   LoRA: List of available LoRA files (perhaps via the LoRA loader’s listing or a folder scan).
+   VAE: Similarly, list VAE filenames to choose from.
+   If multiple selections are allowed, we will allow adding items to the list easily (maybe checkboxes or a plus-button to add another slot).
+   For numeric ranges (CFG scale, Steps, Clip skip, etc.), provide an input that can accept comma-separated values or a range generator:
+   We might allow a syntax like start:stop:step to quickly specify a range (and parse it into list of values), or simply ask for a list of numbers (with a helper to fill ranges).
+   Alternatively, include spin boxes to add values one by one. We can also integrate with the concept of Easy-Grids’ Float List/Int List: for example, let the user enter something like “0, 0.5, 1.0” for flux guidance, or “10,20,30” for steps.
+   For text prompts variation, we have a couple options:
+   Simplest: treat the entire prompt as a string and allow the user to input multiple prompt variants (perhaps separated by a special delimiter or via a multiline field where each line is a different prompt). The axis will then swap the entire prompt for each value.
+   More advanced: allow specifying a search-and-replace or a placeholder in the prompt. E.g., user writes the base prompt in their Text node like “A portrait of [styles] woman” and in the axis values they supply different strings for [styles] (like “a cyberpunk”, “a victorian”, etc.). TinyTerra’s %search;replace% functionality
+   runcomfy.com
+   and Efficiency’s Prompt S/R hint at this idea. This might be a stretch goal; initially, we can require full prompt variants or manual setup.
+   We will ensure that if prompt text is varied, it can feed into the Positive (or Negative) prompt input of the model pipeline easily (likely through a Text concatenation or by directly connecting a Text node input).
+   For boolean or toggle parameters (if any, like using a feature on/off), we can allow values like True/False in the list.
+   Axis Labels: By default, the system will generate labels for each value to display on the grid. The user can control this:
+   There will be a text field for “X Axis Label Prefix” and “Y Axis Label Prefix” (and Z if needed) – if the user wants to prefix the labels (e.g. “CFG=” so the labels read “CFG=7, CFG=10, …”). By default, we might use the parameter name as prefix (e.g. “Model: ” or “Sampler: ”) unless turned off.
+   We will automatically use either the value itself or a short description as the label. For instance, for model filenames we might strip the extension. For prompts, possibly use a truncated first few words if too long.
+   We will also include options for label formatting similar to TinyTerra’s tv_label/itv_label concept
+   github.com
+   (though we’ll hide complexity from user): essentially provide a toggle between showing just the value vs. showing “parameter: value”. Users who want very compact labels can choose value-only, while others might prefer seeing the parameter name included. By default, we’ll include the name or prefix so grids are self-explanatory.
+   Font size and max label length can be set in the Combiner node (like QQ’s label_length and font_size
+   github.com
+   ). We’ll expose those settings in the Combiner UI or let it inherit sensible defaults.
+   Axis Combination Limits: The node will display the computed total number of images = (#X values × #Y values × #Z values). This gives the user feedback on how many images will be generated (important for performance awareness). If this number is extremely large, we might warn the user or require confirmation to avoid accidental huge runs.
+   Dynamic Field Enable/Disable: If the user selects “None” for Z axis, the UI for Z values will hide or disable. Similarly, if they only want an X or a 1D plot, we could allow Y to be “None” and then it just generates a 1-row grid. We will make sure the UI updates logically based on selections, using ComfyUI’s capabilities for dynamic widgets (TinyTerra does something similar with dynamic widget showing/hiding
+   runcomfy.com
+   ).
+3. Execution Flow (One-Click Generation)
+   The behind-the-scenes execution will work as follows:
+   When the user hits Generate, the Controller node will take the lists of X, Y, Z values and iterate over all combinations. For each combination, it will set the axis outputs to the current values and emit a forward execution. This will propagate through the rest of the graph (where those outputs are connected) and ultimately produce an image from the KSampler (or decoder).
+   We plan to implement this by leveraging ComfyUI’s queue system or looping mechanism. There are a few possibilities:
+   Use a technique similar to comfy-easy-grids: internally queue multiple jobs. The Create Image Grid node likely uses api.queuePrompt() calls or similar to push multiple executions. We can replicate that: the first execution of the Controller will schedule the next N-1 executions automatically with the different param values. All images will then be generated in sequence.
+   Alternatively, implement an internal loop in the node’s execute method (since custom nodes can produce multiple outputs perhaps) – but ComfyUI typically expects one output per execution, so queuing separate executions is safer.
+   We will assign each grid run a unique ID (much like QQ’s unique_id control
+   runcomfy.com
+   ) that gets passed to the Combiner, so it knows which images belong together. This prevents mixing images from separate plots if two are run concurrently.
+   Concurrency & Caching: We will likely generate images sequentially (one combination at a time) to reuse the same pipeline and avoid memory spikes. However, to improve efficiency when switching heavy models (checkpoints, VAEs, etc.), we plan to cache models and other resources. For example, if X axis is models A, B, C, we could load each model once at the start (or keep loaded when switching) to avoid repeatedly loading from disk. Efficiency nodes explicitly had a cache_models option for this
+   runcomfy.com
+   ; we can implement a lightweight caching strategy: perhaps load each required model in memory, or use ComfyUI’s existing model caching (if any). At minimum, ensure that when we switch model, we do it in a way that ComfyUI’s model loader doesn’t fully unload/reload if not necessary.
+   The Combiner node will receive each image as it’s produced. It will hold images in a buffer until the expected count is reached, then assemble the grid:
+   We’ll arrange images in row-major order (X axis varying horizontally, Y axis vertically). The number of columns = number of X values (by default, unless we implement a wrap via a “max columns” option similar to QQ’s max_columns
+   runcomfy.com
+   – we might allow the grid to wrap if too wide).
+   It will draw the labels on the top of each column and/or side of each row. We can use a simple Python imaging library (PIL/Pillow) to overlay text, or possibly leverage the images-grid-comfy-plugin that QQ-nodes uses behind the scenes
+   github.com
+   . We may consider using that plugin to avoid reinventing the wheel for combining images and drawing text. (The QQ readme notes that their node injects the LEv145 images-grid plugin for grid assembly
+   github.com
+   – perhaps we can directly call that code or include it.)
+   Font style can be basic (white text with black outline for visibility, for example).
+   Z-axis output: If Z is used (say Z has 2 values meaning two separate grids for e.g. two different prompts), we have options:
+   The Combiner could output a list of images (all grids) once done. Or,
+   It could output one image at a time and require the user to connect a Save node that handles it. But that’s less convenient.
+   Another approach: output a single large image where grids are concatenated vertically or horizontally with a separator and a label for Z. But that might be unwieldy for many Z values.
+   Probably simplest: output as a list or just sequentially output multiple images (ComfyUI might not handle multiple outputs from one execution easily, so list is better).
+   We will likely output a List of images if Z axis is used, along with maybe a text list of Z labels. The user can then handle it (perhaps with a custom save that can save all in a folder). We’ll detail this behavior in documentation so it’s clear.
+   Using Standard Nodes: Our design ensures the actual image generation still uses standard ComfyUI nodes:
+   The user’s workflow will include a Checkpoint Loader, Sampler, etc., which produce the image. We simply feed different values into them each iteration. For example, if varying Model, the CheckpointLoader’s ckpt_name field will be driven by our Controller’s X output (string). The user would expose ckpt_name as an input on the loader node and connect the X output to it. Our node will set it to each model filename in turn for each run. Similarly, for numeric parameters like Steps or CFG, we connect to the sampler’s inputs (these are already exposable in ComfyUI). This way, we use “any sampler” – our node doesn’t re-implement sampling, it just feeds values to the existing KSampler. This satisfies the requirement of not being locked into a custom sampler node.
+   For LoRAs, one approach is to have the LoRA Loader’s “model path” input connected to our output, cycling through LoRA filenames. Alternatively, we could vary prompt text by injecting <lora:name:weight> tokens (some users do LoRA via prompt text). But a cleaner method is connecting to a LoRA apply node. We will investigate how ComfyUI applies LoRAs by node and support that.
+   For prompts, the user can use a Text node for their prompt and we can connect our output to it (maybe via a Text Concatenator if inserting words). If doing entire prompt variations, it might be easiest to have multiple prompts in a String List node and connect our axis output to the Text node’s text input.
+   Guidance for Flux: If the parameter is something specific like “Flux guidance strength” (assuming Flux is a model that has a unique guidance parameter separate from CFG), we will allow that to be varied by, say, connecting to a node or API that controls flux guidance. This might require the user to expose that parameter on a Flux-specific node. Since Flux is new, we’ll ensure our design is generic enough to plug into any float or int parameter exposed in the workflow.
+4. Labeling and Grid Customization
+   Producing a nicely annotated grid is a major part of the user experience. Features for this include:
+   Automatic Label Generation: As mentioned, we’ll derive labels from the values. For each axis value, we generate a label string. The Combiner node will have inputs for row_labels and col_labels (and possibly an overall title or Z labels). By default, our Controller can feed these in automatically:
+   The Controller can output a list of X labels and list of Y labels once the values are set (similar to how Easy-Grids expects String List inputs for labels
+   runcomfy.com
+   , but in our case we can supply them directly).
+   If needed, we can also allow the user to override these label lists via optional inputs – e.g. if they want abbreviated or custom names not exactly matching the values. If an override is not provided, we use the auto labels.
+   Styling Options: In the Combiner UI, provide settings for:
+   Font size (with a reasonable default, e.g. 20px).
+   Grid cell gap (pixel spacing between images, default perhaps 5-10px)
+   github.com
+   .
+   Maybe font color or style, though likely white text with black outline is universally readable so we might fix that.
+   Max columns before wrap (if user wants to break a very large grid into multiple rows – but since Y axis already provides rows, “max columns” would effectively limit X length and overflow to additional grid images; this is an advanced feature, we can defer unless needed).
+   Background color for the label area if we want a band behind the labels (or we can just overlay on images if they have space at edges).
+   Page Size / Z usage: If Z-axis is large, we might allow showing one “page” (grid) at a time. We can implement a page slider in the UI for preview (this is more advanced and might not be necessary if we output all images at once).
+   Interactivity vs Static Output: Initially, the output will be static images. A possible enhancement (future) is an interactive HTML output where you can toggle through Z values or view a high-resolution grid in the UI. However, that’s beyond core requirements – we will focus on static image grids that can be saved.
+5. Example Use Cases
+   To illustrate how the new nodes will work (and to guide development):
+   Example 1: Model vs CFG plot. User wants to compare two models (A and B) at different CFG scales (5, 10, 15) using the same prompt.
+   They place the Controller node and set X Axis = Model, select A and B; Y Axis = CFG Scale, enter [5, 10, 15]; Z Axis = None.
+   They connect the Controller’s X output to the Checkpoint Loader’s model name, and the Y output to the KSampler’s CFG input.
+   They connect KSampler’s image output to the Combiner node.
+   The Combiner automatically gets X labels (“Model A”, “Model B”) and Y labels (“CFG5”, “CFG10”, “CFG15” or with prefix “CFG=”).
+   Upon running, it generates 2×3 = 6 images, then Combiner outputs a single 2-column by 3-row grid image with labels on top of each column (Model names) and at the left of each row (CFG values). The user can then preview or save this grid.
+   What happens behind the scenes: The node will queue 6 runs. It may load model A for first run, then model B for second run, etc., switching back and forth – we might optimize to do AAA… then BBB… to avoid thrashing, but since we need a grid with A and B as columns, we might generate in row-major order (all X for Y1, then Y2). We will consider caching both models in memory to reduce load time.
+   Example 2: Sampler vs Prompt Variation. User wants to see how different samplers render two different descriptions.
+   X = Sampler, choose Euler vs DPM++ 2M Karras; Y = Prompt, enter “a sunny landscape” and “a rainy landscape” as two variants (or use prompt placeholder approach).
+   The user connects X output to the Sampler node’s sampler-name input, and Y output to the positive Prompt text (maybe via a Text node that takes this string).
+   Grid will be 2×2: columns = {Euler, DPM2M}, rows = {sunny, rainy}. Labels reflect sampler names and an abbreviated prompt label (or user manually sets row labels to “Sunny” / “Rainy” for brevity).
+   All 4 images are generated and combined.
+   Example 3: Three-axis plot. User tests two LoRAs at different strengths across three seeds.
+   X = LoRA, values = {No LoRA, Style1, Style2} (with possibly weight 1.0 for style LoRAs embedded in selection or separate weight axis if needed); Y = Seed, values = {100, 200, 300}; Z = LoRA Strength, values = {0.5, 1.0} (this means two grids, one at each strength level).
+   This will produce 2 (Z) _ 3 (X) _ 3 (Y) = 18 images, output as 2 separate 3x3 grids. The Combiner could output a list [Grid_strength0.5, Grid_strength1.0].
+   Each grid’s column labels are LoRA names (with “None” or “No LoRA” for the baseline), row labels are seeds, and each grid has a title or annotation indicating the strength (0.5 or 1.0).
+   The user can then examine the effect of LoRA and strength on different seeds.
+   These use cases ensure our design covers multiple parameter types simultaneously, a key advantage. The system should be robust to any mix (within reason – some combinations might not make sense, but we won’t restrict it programmatically).
+6. Performance Considerations
+   Generating large grids (dozens of images) can be slow or memory-heavy. We will incorporate some features to mitigate issues:
+   Progress Feedback: The Combiner will update a preview as images arrive (like QQ’s accumulator preview output
+   github.com
+   ). The node UI can also show a counter of how many images have been generated out of total. This way the user knows it’s working and can estimate time remaining.
+   Cancellation: If the user stops the queue, our nodes should handle it gracefully (partially filled grid will reset on next run as needed). The unique ID mechanism will help ensure a canceled run doesn’t erroneously carry over images to the next.
+   Memory: For grids with many images, memory might become an issue. We might implement an option akin to QQ’s page_size
+   github.com
+   to split a very large grid into smaller chunks (e.g., if generating 100 images, do 25 at a time and output 4 grids). However, by default we assume moderate grid sizes. This is an advanced option for users who truly need it.
+   Threading: ComfyUI typically runs GPU tasks sequentially unless using batches. We will ensure our queuing doesn’t try to run multiple combos in parallel unintentionally (unless the user specifically wanted to use batch size to generate multiple images simultaneously – that’s a different scenario, possibly outside scope of X/Y plot which usually changes parameters per image, not suitable for same-batch generation).
+   Model Switching Overhead: As noted, caching models/VAEs will be important if those are varied. We can load all needed models at the start of execution (perhaps by pre-loading them via the Loader node or an API call) to avoid repetitive disk I/O. After the grid, unload any that aren’t needed to free VRAM. This approach will draw from Efficiency’s model caching idea
+   runcomfy.com
+   .
+   Implementation Plan
+   We will implement the project in stages: Phase 1: Basic X/Y Plot Node (happy path with one grid).
+   Develop the Controller node with support for two axes (X,Y) initially. Focus on a few core parameter types (models, samplers, CFG, steps) to get the mechanism working.
+   Implement the queuing of jobs for combinations. Test that we can programmatically queue multiple executions via the ComfyUI API. Ensure the outputs (like different model names) properly feed into the model loader on each run.
+   Develop a simple Combiner that accumulates images and once all are received, outputs a grid image (we can use PIL to stitch images in a grid layout for now). Add basic label drawing.
+   Test with simple scenarios (vary model vs CFG, etc.) and verify the grid image output and labels.
+   Phase 2: Expand to Z axis and more parameters.
+   Extend the Controller to handle an optional Z axis loop (probably by nesting another loop or running multiple XY cycles). Ensure multiple grid outputs can be handled (perhaps output a list of images, or sequential outputs; we’ll decide based on ComfyUI capabilities).
+   Add UI support for LoRA, VAE, prompts, seed, etc. – this may involve writing helper code to list files (for models, VAEs, LoRAs) and to parse user input lists for numbers or text.
+   Incorporate prompt variation logic (maybe a simple whole-prompt swap at first).
+   Add Clip skip support (this could be done by connecting to the Checkpoint loader’s clip skip input, if exposed).
+   Ensure that multiple parameter types can be varied at once (like one axis numeric, another axis categorical).
+   Phase 3: UI Refinement and Polishing.
+   Improve the node descriptions, tooltips, and default values for a polished feel. For instance, when the user selects a parameter in the dropdown, we can populate a placeholder or example in the values field to guide them (e.g. “enter comma-separated values”).
+   Implement dynamic showing/hiding of fields (using ComfyUI’s dynamic widget support) so the UI is not cluttered with irrelevant inputs
+   runcomfy.com
+   .
+   Add error handling and validation: e.g., if a user leaves a value list empty for a selected axis, show a warning; if the parameter type requires additional setup (like no Checkpoint Loader connected for a model axis), we can detect that and warn.
+   Integrate advanced label options: allow the user to specify a custom label list if they really want to override, or perhaps toggle between “Value” vs “Name: Value” label style.
+   Aesthetic polish: choose a pleasant default color for the nodes, maybe group them in a custom category in ComfyUI (“XYZ Nodes” category) for easy discovery.
+   Phase 4: Optimization and Edge Cases.
+   Test edge cases like: only 1 value in an axis (should essentially degenerate to a 1-row or 1-col grid), using the node in an already batched context (probably uncommon), extremely long prompt texts (ensure label doesn’t overflow – wrap text if over a certain length
+   github.com
+   ).
+   If performance of assembling images with PIL is slow for high-res images, consider using the optimized library from images-grid plugin (since QQ-nodes mention injecting that for efficient tiling
+   github.com
+   ).
+   Verify compatibility with SDXL workflows (SDXL has two model passes – base and refiner. Our design should allow varying things in an SDXL pipeline too. Likely it works similarly, but we may test an SDXL prompt vs. something grid).
+   Memory test with varying models: ensure model A and B switching does not cause CUDA OOM (maybe unload one before loading next if both can’t reside in VRAM simultaneously – caching on CPU if necessary).
+   User abort testing: if user stops midway, next run should be able to reset properly (we’ll implement a reset mechanism possibly triggered by a new execution ID).
+   Phase 5: Documentation and Examples.
+   Write a user guide with examples (similar to those described above) so users can quickly understand how to use the nodes. Emphasize that no scripting is needed – just connect and go.
+   Provide example workflows JSON (perhaps include a few typical ones, like “Model_vs_CFG_XY.json”) as part of the repo.
+   Throughout development, we’ll incorporate feedback from testers to ensure the UI is truly intuitive and that we didn’t miss any important use-case. The result will be a robust “XYZ Plot” feature for ComfyUI that dramatically simplifies experimentation.
+   Conclusion
+   By blending the best aspects of existing solutions and focusing on user-centric design, this project will deliver an XYZ grid comparison tool for ComfyUI that is both powerful and easy to use. Creators will be able to set up complex multi-parameter comparisons in just a few clicks – no coding, no manual stitching. The grids produced will be neatly labeled and customizable, suitable for analyzing results or sharing with others. This fills an important gap in ComfyUI’s toolkit, empowering users to explore models, prompts, and settings efficiently and with confidence in the interface. Ultimately, our custom nodes will make advanced AI art workflows more accessible, turning what was once a manual, error-prone process into a streamlined experience. By supporting everything from model and sampler swaps to subtle parameter tweaks, all in a polished UI, we help users focus on creativity and insight rather than technical hassle. This project plan lays out the path to achieve that goal, and with careful implementation, the “best XYZ plot nodes” for ComfyUI will soon become a reality.
