Self-hosted LLM gateway with one OpenAI-compatible API
Bifrost is a self-hosted gateway that puts every large language model call behind one OpenAI-compatible API. An application points its existing OpenAI client at the gateway, and Bifrost routes the request to whichever provider is configured, so switching models or spreading load across providers is a configuration change rather than a rewrite.
