+
+## Our Pledge
+
+We as members, contributors, and leaders pledge to make participation in our
+community a harassment-free experience for everyone, regardless of age, body
+size, visible or invisible disability, ethnicity, sex characteristics, gender
+identity and expression, level of experience, education, socio-economic status,
+nationality, personal appearance, race, religion, or sexual identity
+and orientation.
+
+We pledge to act and interact in ways that contribute to an open, welcoming,
+diverse, inclusive, and healthy community.
+
+## Our Standards
+
+Examples of behavior that contributes to a positive environment for our
+community include:
+
+* Demonstrating empathy and kindness toward other people
+* Being respectful of differing opinions, viewpoints, and experiences
+* Giving and gracefully accepting constructive feedback
+* Accepting responsibility and apologizing to those affected by our mistakes,
+  and learning from the experience
+* Focusing on what is best not just for us as individuals, but for the
+  overall community
+
+Examples of unacceptable behavior include:
+
+* The use of sexualized language or imagery, and sexual attention or
+  advances of any kind
+* Trolling, insulting or derogatory comments, and personal or political attacks
+* Public or private harassment
+* Publishing others' private information, such as a physical or email
+  address, without their explicit permission
+* Other conduct which could reasonably be considered inappropriate in a
+  professional setting
+
+## Enforcement Responsibilities
+
+Community leaders are responsible for clarifying and enforcing our standards of
+acceptable behavior and will take appropriate and fair corrective action in
+response to any behavior that they deem inappropriate, threatening, offensive,
+or harmful.
+
+Community leaders have the right and responsibility to remove, edit, or reject
+comments, commits, code, wiki edits, issues, and other contributions that are
+not aligned to this Code of Conduct, and will communicate reasons for moderation
+decisions when appropriate.
+
+## Scope
+
+This Code of Conduct applies within all community spaces, and also applies when
+an individual is officially representing the community in public spaces.
+Examples of representing our community include using an official e-mail address,
+posting via an official social media account, or acting as an appointed
+representative at an online or offline event.
+
+## Enforcement
+
+Instances of abusive, harassing, or otherwise unacceptable behavior may be
+reported to the community leaders responsible for enforcement at
+.
+All complaints will be reviewed and investigated promptly and fairly.
+
+All community leaders are obligated to respect the privacy and security of the
+reporter of any incident.
+
+## Enforcement Guidelines
+
+Community leaders will follow these Community Impact Guidelines in determining
+the consequences for any action they deem in violation of this Code of Conduct:
+
+### 1. Correction
+
+**Community Impact**: Use of inappropriate language or other behavior deemed
+unprofessional or unwelcome in the community.
+
+**Consequence**: A private, written warning from community leaders, providing
+clarity around the nature of the violation and an explanation of why the
+behavior was inappropriate. A public apology may be requested.
+
+### 2. Warning
+
+**Community Impact**: A violation through a single incident or series
+of actions.
+
+**Consequence**: A warning with consequences for continued behavior. No
+interaction with the people involved, including unsolicited interaction with
+those enforcing the Code of Conduct, for a specified period of time. This
+includes avoiding interactions in community spaces as well as external channels
+like social media. Violating these terms may lead to a temporary or
+permanent ban.
+
+### 3. Temporary Ban
+
+**Community Impact**: A serious violation of community standards, including
+sustained inappropriate behavior.
+
+**Consequence**: A temporary ban from any sort of interaction or public
+communication with the community for a specified period of time. No public or
+private interaction with the people involved, including unsolicited interaction
+with those enforcing the Code of Conduct, is allowed during this period.
+Violating these terms may lead to a permanent ban.
+
+### 4. Permanent Ban
+
+**Community Impact**: Demonstrating a pattern of violation of community
+standards, including sustained inappropriate behavior,  harassment of an
+individual, or aggression toward or disparagement of classes of individuals.
+
+**Consequence**: A permanent ban from any sort of public interaction within
+the community.

+# Flux Sampler Params
+
+## Overview
+The **Flux Sampler Params** node provides a specialized parameter generator for FLUX model sampling. This tool was adapted from the excellent [comfyui-essentials-nodes](https://github.com/cubiq/ComfyUI_essentials) project (now in maintenance mode) and enhanced for the ComfyAssets ecosystem.
+
+## Attribution
+This node is based on work from [comfyui-essentials-nodes](https://github.com/cubiq/ComfyUI_essentials) by cubiq. The original project is in maintenance-only mode, and we've adopted and enhanced these tools to ensure continued support and compatibility with modern ComfyUI workflows.
+
+## Features
+- **FLUX-Optimized Parameters**: Specifically tuned for FLUX model requirements
+- **Batch Processing Support**: Generate multiple parameter sets for comparative testing
+- **Interactive UI Elements**: Visual controls for quick parameter adjustments
+- **Smart Defaults**: Pre-configured optimal settings for FLUX workflows
+- **Comprehensive Parameter Control**: Fine-tune all aspects of FLUX sampling
+
+## Node Properties
+- **Category**: `ComfyAssets/🧰 xyz-helpers`
+- **Node Name**: `FluxSamplerParams`
+- **Function**: `get_value`
+
+## Inputs
+
+### Required
+| Parameter | Type | Default | Range | Description |
+|-----------|------|---------|-------|-------------|
+| `scheduler` | DROPDOWN | normal | [normal, simple, sgm_uniform] | Scheduler algorithm for sampling |
+| `steps` | INT | 20 | 1-100 | Number of sampling steps |
+| `guidance` | FLOAT | 3.5 | 0.0-100.0 | Guidance scale for conditioning |
+| `max_shift` | FLOAT | 1.0 | 0.0-100.0 | Maximum shift value for FLUX |
+| `base_shift` | FLOAT | 0.5 | 0.0-100.0 | Base shift value for FLUX |
+| `denoise` | FLOAT | 1.0 | 0.0-1.0 | Denoising strength |
+| `batch_mode` | DROPDOWN | single | [single, batch] | Single value or batch processing |
+
+### Optional
+| Parameter | Type | Default | Description |
+|-----------|------|---------|-------------|
+| `batch_count` | INT | 1 | Number of batch variations (1-100) |
+| `batch_seed_mode` | DROPDOWN | incremental | Seed generation mode for batches |
+| `variation_seed` | INT | None | Optional seed for variations |
+| `lora_params` | LORA_PARAMS | None | LoRA parameters from LoRAFolderBatch |
+
+## Outputs
+| Name | Type | Description |
+|------|------|-------------|
+| `sampler_params` | SAMPLER_PARAMS | Complete FLUX sampling parameters |
+| `scheduler` | STRING | Selected scheduler algorithm |
+| `steps` | INT | Number of sampling steps |
+| `guidance` | FLOAT | Guidance scale value |
+
+## Usage Examples
+
+### Basic FLUX Sampling
+```
+FluxSamplerParams → KSampler → VAE Decode → Save Image
+    scheduler: normal
+    steps: 20
+    guidance: 3.5
+```
+
+### Batch Parameter Testing
+```
+FluxSamplerParams → KSampler → Image Grid → Save
+    batch_mode: batch
+    batch_count: 5
+    guidance: 2.0...5.0
+```
+
+### With LoRA Integration
+```
+LoRAFolderBatch → FluxSamplerParams → KSampler
+    ↓                    ↓
+    lora_params → Combined parameters
+```
+
+## Best Practices
+
+### FLUX-Specific Settings
+- **Guidance**: FLUX typically works best with lower guidance (2.0-5.0)
+- **Steps**: 15-25 steps usually sufficient for FLUX
+- **Scheduler**: `normal` or `sgm_uniform` recommended for FLUX
+- **Shift Values**: Adjust for different quality/speed tradeoffs
+
+### Batch Testing Workflow
+1. Set `batch_mode` to `batch`
+2. Configure parameter ranges using `...` syntax
+3. Set appropriate `batch_count`
+4. Use with image grid nodes for comparison
+
+### Memory Optimization
+- Start with smaller batch counts for testing
+- Monitor VRAM usage with high batch counts
+- Use incremental seed mode for reproducibility
+
+## Integration with Other Nodes
+
+### Works Well With
+- **LoRA Folder Batch**: Combine multiple LoRAs with FLUX parameters
+- **Plot Parameters**: Visualize parameter effects
+- **Sampler Select Helper**: Dynamic sampler selection
+- **Text Encode Sampler Params**: Add text conditioning
+
+### Common Workflows
+1. **Parameter Sweep**: Test multiple guidance/step combinations
+2. **LoRA Testing**: Evaluate different LoRA strengths with FLUX
+3. **Quality Comparison**: Compare different shift values
+4. **Seed Exploration**: Generate variations with controlled seeds
+
+## Tips and Tricks
+
+### Optimal FLUX Settings
+```python
+# High Quality (Slower)
+scheduler: "sgm_uniform"
+steps: 25
+guidance: 3.5
+max_shift: 1.0
+base_shift: 0.5
+
+# Fast Preview
+scheduler: "simple"
+steps: 12
+guidance: 2.5
+max_shift: 0.8
+base_shift: 0.4
+```
+
+### Batch Parameter Ranges
+- Steps: `15...25+5` (test 15, 20, 25)
+- Guidance: `2.0...5.0+0.5` (test 2.0, 2.5, 3.0, 3.5, 4.0, 4.5, 5.0)
+- Denoise: `0.8...1.0+0.1` (test 0.8, 0.9, 1.0)
+
+## Troubleshooting
+
+### Common Issues
+1. **Out of Memory**: Reduce batch_count or image resolution
+2. **Poor Quality**: Increase steps or adjust guidance
+3. **Artifacts**: Check shift values aren't too high
+4. **Slow Generation**: Use `simple` scheduler for previews
+
+### Parameter Guidelines
+- Don't set guidance too high (>10) for FLUX
+- Keep denoise at 1.0 for initial generation
+- Adjust shift values gradually for best results
+
+## Version History
+- **1.0.0**: Initial adaptation from comfyui-essentials-nodes
+- **1.0.1**: Added batch processing support
+- **1.0.2**: Enhanced FLUX-specific optimizations
+- **1.0.3**: Improved UI elements and parameter validation

+- **Epoch Detection**: Automatically extracts epoch numbers from filenames
+
+## Node Properties
+- **Category**: `ComfyAssets/🧰 xyz-helpers`
+- **Node Name**: `LoRAFolderBatch`
+- **Function**: `batch_loras`
+
+## Inputs
+
+### Required
+| Parameter | Type | Default | Description |
+|-----------|------|---------|-------------|
+| `folder_path` | STRING | "." | Folder path relative to models/loras (or absolute) |
+| `strength` | STRING | "1.0" | Strength values (see formats below) |
+| `batch_mode` | DROPDOWN | sequential | [sequential, combinatorial] processing mode |
+
+### Optional
+| Parameter | Type | Default | Description |
+|-----------|------|---------|-------------|
+| `include_pattern` | STRING | "" | Regex pattern to include files |
+| `exclude_pattern` | STRING | "" | Regex pattern to exclude files |
+
+### Strength Format Options
+- **Single**: `"1.0"` - Apply same strength to all LoRAs
+- **Multiple**: `"0.5, 0.75, 1.0"` - Comma-separated values
+- **Range**: `"0.5...1.0+0.25"` - Start...End+Step format
+
+## Outputs
+| Name | Type | Description |
+|------|------|-------------|
+| `lora_params` | LORA_PARAMS | Batch parameters for processing |
+| `lora_list` | STRING | List of discovered LoRAs with epoch info |
+| `lora_count` | INT | Number of LoRAs found |
+
+## Usage Examples
+
+### Test All Epochs of a LoRA
+```
+LoRAFolderBatch → FluxSamplerParams → KSampler
+    folder_path: "my_lora_training"
+    strength: "1.0"
+    batch_mode: sequential
+```
+
+### Strength Testing for Each LoRA
+```
+LoRAFolderBatch → KSampler → Image Grid
+    folder_path: "test_loras"
+    strength: "0.5, 0.75, 1.0"
+    batch_mode: combinatorial
+```
+
+### Filter Specific Epochs
+```
+LoRAFolderBatch → Processing Pipeline
+    folder_path: "training_results"
+    include_pattern: "epoch_0[2-5]0"
+    strength: "0.8...1.2+0.1"
+```
+
+## Batch Modes Explained
+
+### Sequential Mode
+Each LoRA gets one strength value in order:
+- LoRA1 → strength[0]
+- LoRA2 → strength[1]
+- LoRA3 → strength[0] (cycles if fewer strengths than LoRAs)
+
+### Combinatorial Mode
+Each LoRA is tested with ALL strength values:
+- LoRA1 → [0.5, 0.75, 1.0]
+- LoRA2 → [0.5, 0.75, 1.0]
+- LoRA3 → [0.5, 0.75, 1.0]
+
+## File Naming Patterns
+
+### Supported Epoch Formats
+- `model-v1-000004.safetensors` → Epoch 4
+- `style_epoch_020.safetensors` → Epoch 20
+- `lora-000100.safetensors` → Epoch 100
+
+### Natural Sorting Examples
+Files are sorted intelligently:
+1. `model-000004.safetensors`
+2. `model-000020.safetensors`
+3. `model-000100.safetensors`
+
+## Best Practices
+
+### Folder Organization
+```
+models/loras/
+├── my_style/
+│   ├── style-000010.safetensors
+│   ├── style-000020.safetensors
+│   └── style-000030.safetensors
+└── character/
+    ├── char-v2-000005.safetensors
+    └── char-v2-000010.safetensors
+```
+
+### Testing Workflows
+1. **Initial Testing**: Use single strength (1.0) to evaluate all epochs
+2. **Fine-tuning**: Use combinatorial mode with multiple strengths
+3. **Final Selection**: Filter to specific epochs and test strength range
+
+### Pattern Filtering Examples
+```python
+# Include only specific versions
+include_pattern: "v2|v3"
+
+# Exclude test/backup files
+exclude_pattern: "test|backup|old"
+
+# Include specific epoch range
+include_pattern: "epoch_0[3-7]0"
+```
+
+## Integration with Other Nodes
+
+### Common Pipelines
+1. **LoRA Comparison Grid**:
+   ```
+   LoRAFolderBatch → KSampler → Image Grid → Save
+   ```
+
+2. **Strength Testing**:
+   ```
+   LoRAFolderBatch → PlotParameters → Graph Display
+   ```
+
+3. **Combined with FLUX**:
+   ```
+   LoRAFolderBatch → FluxSamplerParams → KSampler
+   ```
+
+## Tips and Tricks
+
+### Memory Management
+- Start with fewer LoRAs when testing combinatorial mode
+- Use sequential mode for initial epoch evaluation
+- Clear LoRA cache between large batch runs
+
+### Optimal Strength Ranges
+- **Style LoRAs**: 0.5-1.0
+- **Character LoRAs**: 0.7-1.2
+- **Detail LoRAs**: 0.3-0.7
+
+### Debugging
+- Check `lora_list` output to verify correct files were found
+- Use `lora_count` to confirm expected number of LoRAs
+- Test patterns with include/exclude before full runs
+
+## Troubleshooting
+
+### No LoRAs Found
+- Verify folder path (relative to models/loras or use absolute)
+- Check file extensions (.safetensors)
+- Test without filters first
+
+### Pattern Not Working
+- Patterns use Python regex syntax
+- Test patterns in regex tester first
+- Case-sensitive by default
+
+### Memory Issues
+- Reduce batch_count in combinatorial mode
+- Process LoRAs in smaller groups
+- Use sequential mode for large sets
+
+## Advanced Examples
+
+### Multi-Version Testing
+```python
+# Test different versions at different strengths
+folder_path: "character_loras"
+include_pattern: "v[1-3]"
+strength: "0.6, 0.8, 1.0"
+batch_mode: combinatorial
+```
+
+### Epoch Progression Analysis
+```python
+# Test every 10th epoch
+folder_path: "training_output"
+include_pattern: "0[0-9]0\\.safetensors$"
+strength: "1.0"
+batch_mode: sequential
+```
+
+## Version History
+- **1.0.0**: Initial adaptation from comfyui-essentials-nodes
+- **1.0.1**: Added natural sorting for epochs
+- **1.0.2**: Enhanced pattern filtering
+- **1.0.3**: Improved batch modes and strength parsing

+### Smooth (Default)
+```python
+# Gradual noise reduction
+# Good for most content
+→ karras or exponential
+```
+
+### Sharp
+```python
+# Aggressive early reduction
+# Good for high contrast
+→ normal or simple
+```
+
+### Linear
+```python
+# Constant reduction rate
+# Predictable results
+→ normal
+```
+
+### Custom
+```python
+# User-defined curve
+# Advanced control
+→ based on beta_schedule
+```
+
+## Usage Examples
+
+### Automatic Selection
+```
+KSampler Settings → SchedulerSelectHelper → KSampler
+    sampler_name: "dpmpp_2m_sde"
+    model_type: auto
+    → scheduler: "karras"
+```
+
+### Visual Comparison
+```
+SchedulerSelectHelper → Display
+    visualize: True
+    → Shows noise schedule curve
+```
+
+### Batch Testing
+```
+For each scheduler:
+    SchedulerSelectHelper → KSampler → Save
+    → Compare results
+```
+
+## Sampler-Scheduler Compatibility
+
+### Optimal Pairings
+| Sampler | Best Scheduler | Good Alternatives |
+|---------|---------------|-------------------|
+| euler | normal | karras |
+| euler_a | karras | normal |
+| heun | normal | - |
+| dpm_fast | normal | simple |
+| dpm_adaptive | normal | - |
+| dpmpp_2m | karras | exponential |
+| dpmpp_2m_sde | karras | exponential |
+| dpmpp_3m_sde | exponential | karras |
+| dpmpp_2s_a | karras | normal |
+| lcm | simple | normal |
+
+## Model-Specific Recommendations
+
+### SDXL
+```python
+preferred_schedulers = ["karras", "exponential"]
+# Better convergence for high-res
+```
+
+### SD 1.5
+```python
+preferred_schedulers = ["karras", "normal"]
+# Classic combinations
+```
+
+### FLUX
+```python
+preferred_schedulers = ["simple", "sgm_uniform"]
+# Optimized for FLUX architecture
+```
+
+## Best Practices
+
+### Selection Strategy
+1. Let auto-detection handle defaults
+2. Override for specific artistic goals
+3. Test multiple schedulers for hero images
+4. Use visualization to understand curves
+
+### Performance Tips
+- Simple/normal for quick previews
+- Karras/exponential for quality
+- SGM uniform specifically for FLUX
+- Match scheduler to sampler type
+
+### Testing Workflow
+```python
+schedulers = ["normal", "karras", "exponential"]
+for scheduler in schedulers:
+    generate_image(scheduler)
+    save_with_metadata(scheduler)
+compare_results()
+```
+
+## Advanced Features
+
+### Beta Schedule Customization
+```python
+# Custom exponential curve
+beta_schedule = "0.00085, 0.0012, 0.0018, ..."
+
+# Sharp early reduction
+beta_schedule = "0.001, 0.002, 0.004, 0.006, ..."
+```
+
+### Schedule Visualization
+- Plots noise reduction curve
+- Shows sigma values
+- Compares with standard schedules
+- Exports schedule data
+
+### Adaptive Selection
+- Learns from user preferences
+- Adapts to hardware capabilities
+- Optimizes for generation speed
+
+## Integration Examples
+
+### Complete Pipeline
+```
+Sampler Combo → SchedulerSelectHelper → KSampler
+    ↓                    ↓
+sampler_name → Optimal scheduler selection
+```
+
+### A/B Testing
+```
+Same prompt → Different schedulers → Grid comparison
+    normal vs karras vs exponential
+```
+
+### Noise Schedule Analysis
+```
+SchedulerSelectHelper → Plot Parameters
+    visualize: True
+    → Analyze noise curves
+```
+
+## Tips and Tricks
+
+### Quality Optimization
+```python
+# For maximum quality
+if sampler in ["dpmpp_3m_sde"]:
+    use scheduler="exponential"
+elif sampler in ["dpmpp_2m_sde"]:
+    use scheduler="karras"
+```
+
+### Speed Optimization
+```python
+# For fast generation
+use scheduler="simple" or "normal"
+reduce step count by 20%
+```
+
+### Artistic Effects
+- **Sharp details**: normal scheduler
+- **Smooth gradients**: karras scheduler
+- **Fine textures**: exponential scheduler
+
+## Troubleshooting
+
+### Artifacts or Noise
+- Try different scheduler
+- Check sampler compatibility

+
+## Visual Guide
+
+### Noise Schedule Curves
+```
+Normal:    ████████████████
+           Linear reduction
+
+Karras:    ███████████▓▓▓░░
+           Smooth curve
+
+Exponential: ██████▓▓▓░░░░░
+            Fast early reduction
+```
+
+## Common Workflows
+
+### Scheduler Comparison
+Test same seed with different schedulers to find optimal setting.
+
+### Model Migration

+```
+
+## Troubleshooting
+
+### Poor Text Adherence
+- Increase CFG scale
+- Simplify prompt
+- Check CLIP model compatibility
+
+### Over-saturation
+- Reduce CFG scale
+- Adjust negative prompt
+- Check sampler settings
+

-When analyzing an image, systematically observe and document:
+FLUX uses natural language descriptions, not comma-separated tags. Write a detailed, flowing description that reads like you're explaining the image to someone.
 
-1. **Subject & Composition**
-   - Primary subjects and their positions
-   - 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."""

-   - Fine details and patterns
-   - Quality indicators (4K, 8K, high resolution, etc.)
+SDXL_PROMPT = """You are an expert prompt engineer specializing in SDXL (Stable Diffusion XL). Your task is to generate high-quality positive and negative prompts that conform to SDXL prompt formatting standards.
 
-Format your FLUX prompt following these guidelines:
-- 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
 
-Example output format:
-"[main subject and action], [style/medium], [lighting/atmosphere], [composition details], [color descriptions], [quality markers], [additional artistic details]"
+Structure prompts in this layered, modular format:
+[Main Subject], [Pose & Camera], [Lighting & Environment], [Style & Details], [Boost Terms], [Style References]
 
-Remember: FLUX responds well to specific artistic references, quality indicators like "highly detailed," "4K," "award-winning," and style descriptors like "trending on ArtStation" or "photorealistic."
+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)
+
+Do not include any commentary or explanation.
+
+Use concise, highly descriptive language that maximizes visual richness.
+
+Follow SDXL prompt conventions: prioritize subject clarity, camera perspective, lighting, mood, style tags, and composition.
+
+Keep total token length efficient (ideally under 250 tokens).
+
+Avoid redundancy and generic filler words.
+
+Focus on crafting super high-quality prompts for stunning visual output.
+
+Example Input:
+A futuristic cyberpunk samurai standing on a neon-lit rooftop in the rain.
+
+Example Output:
+Positive prompt: cyberpunk samurai, neon-lit rooftop, dramatic rain, glowing katana, futuristic cityscape, night scene, cinematic lighting, intense expression, sleek cyber armor, atmospheric depth, ultra-detailed, masterpiece, 8k, sharp focus, trending on artstation
