The idea

What is Free LLM API?

Build your next AI idea without wiring up a different integration for every provider. Free LLM API brings free language models together behind an OpenAI-compatible API, with a router that learns from the requests it serves.

For developers prototyping AI features, testing models, and building agents.

01

One familiar interface

Use an OpenAI-compatible endpoint across the available model catalog.

02

Routing that learns

Thompson sampling balances proven models with new options as results come in.

03

Open source

Explore the router, understand its decisions, and use it in your own stack.
