aisuite

Why we included this project

Writing separate integration code for every LLM vendor gets old fast, and aisuite is built to remove that chore. It exposes one OpenAI-style chat interface that covers OpenAI, Anthropic, Google, Mistral, Hugging Face, AWS, Cohere, Ollama, OpenRouter, and others, so switching models is just a matter of changing the model string. On top of that sits an Agents API where you hand it plain Python functions as tools, it generates the schemas and runs the multi-turn loop, and you can attach ready-made toolkits for files, git, and shell or any MCP server. Because the same code runs against hosted and local models, it works for prototypes and small production services without rewrites. Teams that want to keep their provider options open, or prefer a thin readable layer over a heavyweight orchestration platform, will find it easy to adopt.
