## Supported Tasks

All chat models support:
- Question Answering
- Summarization
- Retrieval Augmented Generation (RAG)
- Classification
- Text Generation
- Code Generation
- Extraction
- Translation
- Function Calling

## Usage Notes

1. **Context Length**: Models with 131K+ context length support long-document processing
2. **Vision Models**: Models with `image_chat` function support multimodal inputs
3. **Function Calling**: Most models support OpenAI-compatible function calling
4. **Multilingual**: Many models support multiple languages (see model specifications)

## Model Selection Guide

- **For general chat**: `ibm/granite-3-8b-instruct` or `meta-llama/llama-3-3-70b-instruct`
