PipeLLM converters let developers keep their existing SDK format while calling models from another provider family.

​
When to Use a Converter

Use a converter route when:
  • your application already speaks OpenAI, Anthropic, or Gemini format
  • you want to switch providers without rewriting request and response handling
  • the native public route does not support the protocol family you need
If your request already matches the target provider protocol, use the native public route instead. See Routing & Protocols.

​
Current Limitation

OpenAI Responses converter routing is not available yet. If your application uses the OpenAI Responses API and needs cross-protocol routing today, use the OpenAI Chat Completions converter at https://api.pipellm.ai/openai/v1/chat/completions.
