What are GPT4Free and Guidance?
GPT4Free
GPT4Free is an open-source project that provides a unified, OpenAI-compatible API and interface for accessing a variety of language and image models. It can be self-hosted as a gateway to route requests across multiple model providers.
- OpenAI-compatible API
- Multiple provider routing
- Self-hosted gateway
- Image and text models
Guidance
Guidance is a programming paradigm from Microsoft for steering language model output with interleaved generation, control flow, and constraints. It can run against locally hosted models to produce reliable structured results.
- Interleaved generation control
- Token healing
- Regex and grammar constraints
- Works with local models
