# Groq Models Information
|
||||
|
||||
## 🚀 Dynamic Model Loading
|
||||
|
||||
The Groq integration now supports **dynamic model loading** from the Groq API! When you have a valid `GROQ_API_KEY` set, the system will automatically fetch the latest available models on startup.
|
||||
|
||||
### How It Works
|
||||
|
||||
1. **At Startup**: The system tries to fetch models from `https://api.groq.com/openai/v1/models`
|
||||
2. **Fallback**: If the API call fails (no key, network issue), it loads from `data/groq_models.json`
|
||||
3. **Cache**: Models are loaded once per ComfyUI session
|
||||
|
||||
### Benefits
|
||||
|
||||
- ✅ Always have access to the latest models
|
||||
- ✅ Automatically get new models as Groq adds them
|
||||
- ✅ No manual updates needed
|
||||
- ✅ Graceful fallback if API is unavailable
|
||||
|

| Model ID | Provider | Context Window | Max Tokens | Description |
|
||||
|----------|----------|----------------|------------|-------------|
|
||||
| `llama-3.3-70b-versatile` | Meta | 131K | 32K | Latest Llama 3.3, very capable |
|
||||
| `llama-3.1-8b-instant` | Meta | 131K | 131K | Fast, efficient Llama 3.1 |
|
||||

|
||||
|
||||
### 👁️ Vision Models
|
||||
|
||||
**Note**: Vision model availability may vary by region and account tier. The API response showed no vision models in the current check, but Groq has supported:
|
||||
- `llama-3.2-90b-vision-preview`
|
||||
- `llama-3.2-11b-vision-preview`
|
||||
|
||||
If vision models aren't available for your account, the vision node will gracefully handle this.
|
||||
|
||||
### 🎙️ Other Models (Not included in text generation)
|
||||
|
||||
The API also returns:
|
||||
- **Whisper** models for speech-to-text
|
||||
- **PlayAI TTS** models for text-to-speech
|
||||
- **Prompt Guard** models for safety filtering
|
||||
|
||||
These are filtered out from the text generation node as they serve different purposes.
|
||||

|
||||
|
||||
## What Was Implemented
|
||||
|
||||

|
||||
- `encode_video()`: Frame extraction and temporal ID generation
|
||||
- `map_to_nearest_scale()`: Temporal mapping using KD-trees
|
||||
- `group_array()`: Frame grouping for 3D packing
|
||||
|
||||
### 2. Technical Implementation
|
||||
|
||||
#### 3D-Resampler Integration
|
||||
|
||||
Correctly implements the paper's approach:
|
||||
```python
|
||||
# Groups frames with temporal IDs
|
||||
frame_ts_id_group = group_array(frame_ts_id, packing_nums)
|
||||
|
||||
# Passes to model for 3D compression
|
||||
answer = model.chat(
|
||||
msgs=msgs,
|
||||
temporal_ids=frame_ts_id_group, # Key parameter
|
||||
...
|
||||
)
|
||||
```
|
||||
|
||||
#### Smart Frame Sampling
|
||||
|
||||
Dynamic frame selection based on video duration:
|
||||
```python
|
||||
if choose_fps * int(video_duration) <= MAX_NUM_FRAMES:
|
||||
packing_nums = 1 # No compression needed
|
||||
else:
|
||||
packing_nums = math.ceil(...) # Calculate optimal compression
|
||||
```
|
||||
|
||||
#### Model Caching
|
||||
|
||||
Efficient model management:
|
||||
```python
|
||||
# Class-level cache shared across instances
|
||||
_model_cache = {}
|
||||
_tokenizer_cache = {}
|
||||
|
||||
# Load once, reuse many times
|
||||
if cache_key in self._model_cache:
|
||||
return cached_model, cached_tokenizer
|
||||
```
|
||||
|
||||
### 3. Integration
|
||||
|
||||
#### Updated Files
|
||||
|
||||
1. **`nodes/__init__.py`**
|
||||
- Added MiniCPM node imports
|
||||
- Registered nodes with ComfyUI

||||
|
||||
2. **`requirements.txt`**
|
||||
- Added transformers>=4.40.0
|
||||
- Added torch>=2.0.0
|
||||
- Added decord>=0.6.0
|
||||
- Added scipy>=1.10.0
|
||||
|
||||
3. **`nodes/minicpm/__init__.py`**
|
||||
- Exports both nodes
|
||||
- Defines display names
|
||||
|
||||
### 4. Documentation
|
||||

|
||||
- Full feature documentation
|
||||
- Usage examples
|
||||

|
||||
- Troubleshooting guide
|
||||
|
||||
2. **`MINICPM_SETUP.md`**
|
||||
- Quick start guide
|
||||
- Installation instructions
|
||||
- System requirements
|
||||
- Common issues and solutions
|
||||
|
||||
3. **`MINICPM_IMPLEMENTATION.md`** (this file)
|
||||
- Implementation summary
|
||||
- Architecture details
|
||||
- Code structure
|
||||
|
||||
### 5. Examples
|
||||
|
||||
Created workflow examples:
|
||||
|
||||
1. **`examples/minicpm/image_example.json`**
|
||||
- Basic image analysis workflow
|
||||
- Shows node connections
|
||||
- Ready to use template
|
||||
|
||||
2. **`examples/minicpm/video_example.json`**
|
||||
- Video analysis workflow
|
||||
- Output visualization
|
||||
- Configuration example
|
||||
|
||||
## Architecture Decisions
|
||||
|
||||
### 1. Lazy Imports
|
||||
|
||||
```python
|
||||
def lazy_import_dependencies():
|
||||
global transformers, decord
|
||||
# Only import when actually needed
|
||||
```
|
||||
|
||||
**Rationale:** Heavy dependencies only loaded when nodes are used, doesn't slow down ComfyUI startup.
|
||||
|
||||
### 2. Model Caching Strategy
|
||||
|
||||
**Class-level caching** instead of instance-level:
|
||||
- Models shared across all node instances
|
||||
- Avoids redundant loads
|
||||
- User can manually unload if needed
|
||||
|
||||
### 3. Error Handling
|
||||
|
||||
Comprehensive error handling with helpful messages:
|
||||
```python
|
||||
except ImportError as e:
|
||||
error_msg = f"Missing dependency: {str(e)}\n\nPlease install..."
|
||||
except Exception as e:
|
||||
error_msg = f"Error analyzing video: {str(e)}"
|
||||
traceback.print_exc()
|
||||
```
|
||||
|
||||
### 4. Following Existing Patterns
|
||||
|
||||
Implemented to match the existing codebase style:
|
||||
- Similar to `ollama/vision_node.py` structure
|
||||
- Uses `CUSTOM_CATEGORY` from constants
|
||||
- Follows `tensor2pil` conversion pattern
|
||||
- Matches error handling approach

||||
|
||||
## Important Notes
|
||||
|
||||
### First Run
|
||||
|
||||
- **First time will be slow**: The model (~17GB) needs to download from Hugging Face
|
||||
- **Requires internet**: For initial model download
|
||||
- **Disk space**: Ensure you have ~20GB free space
|
||||
- **Model location**: `~/.cache/huggingface/hub/` (or `C:\Users\YourName\.cache\huggingface\` on Windows)
|
||||
|
||||
### System Requirements
|
||||
|
||||
**Minimum:**
|
||||
- GPU: 8GB VRAM (for MiniCPM-V-4.5)
|
||||
- RAM: 16GB system RAM
|
||||
- Disk: 20GB free space
|
||||
- OS: Windows 10/11, Linux, macOS
|
||||
|
||||
**Recommended:**
|
||||
- GPU: 16GB+ VRAM (RTX 3090, 4090, A6000, etc.)
|
||||
- RAM: 32GB+ system RAM
|
||||
- Disk: SSD with 50GB+ free space
|
||||
- CUDA: Latest version
|
||||
|
||||
**Can run on CPU** but will be very slow (not recommended).
|
||||
|
||||
### Video Requirements
|
||||
|
||||
For video processing, you need:
|
||||
- **decord** library (included in requirements)
|
||||
- Supported formats: MP4, AVI, MOV, MKV, WebM
|
||||
- Video codec: H.264, H.265, VP9 (most common formats work)
|
||||
|
||||
### Troubleshooting
|
||||
|
||||
#### "No module named 'transformers'"
|
||||
```bash
|
||||
pip install transformers
|
||||
```
|
||||
|
||||
#### "No module named 'decord'"
|
||||
```bash
|
||||
pip install decord
|
||||
```
|
||||
|
||||
On Windows, if decord fails, try:
|
||||
```bash
|
||||
pip install decord --no-deps
|
||||
pip install numpy
|
||||
```
|
||||
|
||||
#### "CUDA out of memory"
|
||||
Solutions:
|
||||
1. Close other GPU applications
|
||||
2. Set `device` to "cpu" (slow but works)
|
||||
3. Enable `unload_after_inference` to free memory after each use
|
||||
4. For videos, reduce `max_num_frames` or `fps`
|
||||
|
||||
#### "Model download fails"
|
||||
1. Check internet connection
|
||||
2. Verify Hugging Face is accessible
|
||||
3. Try manual download:
|
||||
```bash
|
||||
pip install huggingface_hub
|
||||
huggingface-cli download openbmb/MiniCPM-V-4_5
|
||||
```
|
||||
|
||||
#### Node doesn't appear in ComfyUI
|
||||
1. Restart ComfyUI completely
|
||||
2. Check console for errors
|
||||
3. Verify installation in correct directory
|
||||
4. Check that `__init__.py` files are present
|
||||
|
||||
## Usage Tips
|
||||
|
||||
### For Best Results
|
||||
|
||||
**Image Analysis:**
|
||||
- Use high-quality images
|
||||
- For OCR, ensure text is clear and readable
|
||||
- Multiple images can be compared in one query
|
||||
- Use thinking mode for complex questions
|
||||
|
||||
**Video Analysis:**
|
||||
- Start with `fps=5` for most videos
|
||||
- Increase fps for fast-action videos (sports, etc.)
|
||||
- Longer videos benefit from lower fps
|
||||
- Short clips can use higher fps
|
||||
|
||||
### Performance Tips
|
||||
|
||||
1. **Keep model loaded**: Don't enable `unload_after_inference` unless you need the memory
|
||||
2. **Batch processing**: Load model once, process multiple items
|
||||
3. **GPU recommended**: 10-100x faster than CPU
|
||||
4. **Thinking mode**: Only enable for complex reasoning tasks
|
||||
|
||||
### Privacy & Offline Use
|
||||
|
||||
- **After first download**, models work fully offline
|
||||
- **No data sent anywhere**: Everything runs locally
|
||||
- **Models are cached**: Delete from `~/.cache/huggingface/` to remove
|
||||
|
||||
## Example Prompts
|
||||
|
||||
### Image Understanding
|
||||
|
||||
- "Describe this image in detail."
|
||||
- "What text is visible in this image?"
|
||||
- "What is the main subject and what are they doing?"
|
||||
- "Compare these two images and describe the differences."
|
||||
- "What colors and artistic style are used here?"
|
||||
|
||||
### Video Understanding
|
||||
|
||||
- "Describe what happens in this video."
|
||||
- "What actions does the person perform?"
|
||||
- "Summarize the key events in this video."
|
||||
- "What is the setting and atmosphere?"
|
||||
- "Track the movement of the red car through the scene."
|
||||
|
||||
## Advanced Usage
|
||||
|
||||
### Multi-turn Conversations
|
||||
|
||||
For images, you can have back-and-forth conversations:
|
||||
|
||||
1. First query: Ask initial question, get `conversation_history`
|
||||
2. Second query: Ask follow-up, feed previous `conversation_history` back in
|
||||
3. Continue as needed
|
||||
|
||||
### Custom Processing
|
||||
|
||||
Adjust parameters for different use cases:
|
||||
|
||||
**Fast preview:**
|
||||
- `enable_thinking`: False
|
||||
- `stream`: False
|
||||
- Keep model loaded
|
||||
|
||||
**Detailed analysis:**
|
||||
- `enable_thinking`: True
|
||||
- `stream`: True (see progress)
|
||||
- Higher quality inputs
|
||||
|
||||
**Video analysis:**
|
||||
- Short clips: `fps=10`, `max_num_frames=180`
|
||||
- Long videos: `fps=3`, `max_num_frames=180`
|
||||
- Very long: `fps=1-2`, adjust as needed
|
||||
|
