1. Clone this repository into your ComfyUI custom_nodes folder:
  ```bash
cd ComfyUI/custom_nodes
git clone https://github.com/EnragedAntelope/ComfyUI-EACloudNodes
  ```
2. Install required packages:
  ```bash
cd ComfyUI-EACloudNodes

- `filter_text`: Text to filter models
- `sort_by`: Sort models by name, pricing, or context length
- `sort_order`: Choose ascending or descending sort order

## Usage Guide

### Basic Text Generation
1. Add an LLM node (OpenRouter or Groq) to your workflow
2. Set your API key
3. Choose a model
4. (Optional) Set system prompt for context/behavior
5. Enter your prompt in the `user_prompt` field
6. Connect the node's output to view results

### Vision Analysis
1. Add an LLM node to your workflow
2. Choose a vision-capable model
3. Connect an image output to the `image_input`
4. For Groq vision models, set 'send_system' to 'no'
5. Add your prompt about the image in `user_prompt`
6. Connect outputs to view response and status

### Advanced Usage
- Use `system_prompt` to set context or behavior
- Adjust temperature and other parameters to control response style
- Select `json_object` format for structured outputs
- Monitor token usage via the status output
- Chain multiple nodes for complex workflows
- Use seed_mode for reproducible outputs (Fixed) or controlled variation (Increment/Decrement)
- Use `additional_params` to set model-specific parameters in JSON format:
  ```json
  {
    "min_p": 0.1,
    "stop": ["\n\n"]
  }
  ```

### Parameter Optimization Tips
- **Temperature**:
  - Lower (0.1-0.3): More focused, deterministic responses
  - Higher (0.7-1.0): More creative outputs
- **Top-p**:
  - Lower (0.1-0.3): More predictable word choices
  - Higher (0.7-1.0): More diverse vocabulary
- **Penalties**:
  - Use `presence_penalty` to reduce topic repetition
  - Use `frequency_penalty` to reduce word repetition
- **Seed Mode**:
  - `fixed`: Use for reproducible outputs (same seed + params = same output)
  - `random`: Use for varied responses each time
  - `increment/decrement`: Use for controlled variation across runs
- **Token Management**:
  - Monitor token usage in status output to optimize costs
  - Adjust `max_completion_tokens` to control response length

### Error Handling
Both nodes provide detailed error messages for common issues:
- Missing or invalid API keys
- Model compatibility issues
- Image size and format requirements
- JSON format validation
- Token limits and usage
- API rate limits and automatic retries
- Parameter validation errors

Enable `debug_mode` in the Groq node for detailed troubleshooting information.
