ReqLLM is a composable Elixir library built on Req and Finch that standardizes LLM API interactions across providers. It offers a high-level API inspired by the Vercel AI SDK with functions like generate_text, stream_text, and generate_object, while provider transports handle the underlying request/response mechanics. The package supports over 1,200 models across 21 provider integrations including major LLM services.
