A fast & asynchronous python API for modern AI development FastApi + Langchain
Features
- AI model switching (Anthropic, OpenAI, Llama, Hugging Face) + Embeddings
- Plug & play for vector DBs (FAISS, Pinecone, Supabase)
- Plug & play for traditional DBs (local Postgres, Supabase)
- Web adapters/retrievers/scrapers
- Multimodal processor for images/voice/text - fully extensible
- Prompt creator & evaluator (the difference in results is astounding when you have really good prompts)
- 3 complete examples of agentic flows (from API request to result)
Extras
- Functionality available via simple CLI commands
- Poetry for package management, easy deployment with Docker, rate limiting, security & scalability,
- Slick documentation with examples
- Lifetime updates - with the speed at which AI is moving I think just this is worth more than the post-beta cost (but that's just me)
