Show HN: An OpenAI API compatible server that uses GitHub Copilot SDK for LLMs
github.comI've been playing around with the new official GitHub Copilot SDK and realized it's a goldmine for building programmatic bridges to their models.
I built this server in Go to act as a OpenAI-compatible proxy. It essentially lets you treat your GitHub Copilot subscription as a standard OpenAI backend for any tool that supports it. I have tested it against OpenWebUI and Langchain.
Key Highlights:
- Official SDK: Built using the new Github Copilot SDK. It’s much more robust than the reverse-engineered solutions floating around and does not use unpublished APIs.
- Tool Calling Support: It maps OpenAI function definitions to Copilot's agentic tools. You can use your own tools/functions through the Copilot without copilot needing access to the said tools just the definitions is enough.
The goal was to create a reliable "bridge" so I can use my subscription models in my preferred interfaces. Very nice :)
