## Adding New Models

See [Development Guide](./development.md) for instructions on adding new model integrations.

## License Compliance

**Important**: Each model has its own license. Please review the model's license before use in production. Some key considerations:

- **Apache 2.0**: Permissive, commercial-friendly
- **MIT**: Permissive, commercial-friendly
- **Qwen Research License**: Research use, may have restrictions
- **Tencent Hunyuan Community License**: Custom license, review terms
- **CC BY-NC 4.0**: Non-commercial only

Always verify license terms before deployment in production environments.

## Model Updates
