A Python library and local server that reverse engineers Microsoft Copilot's free web chat into an OpenAI-compatible REST API, giving access to GPT-4 and GPT-5 models without API keys or billing. It supports streaming, multi-turn conversations, and works as a drop-in replacement for the official OpenAI SDK.
Use cases
- use gpt-4 for free without an openai api key
- point existing openai sdk apps at a local free llm endpoint
- build chatbots on top of microsoft copilot
- stream llm responses in python
- run a local openai-compatible api server
- access copilot in regions where anonymous access is blocked
When to choose
- you want free GPT-4/GPT-5 access using a Microsoft account instead of paid API billing
- you already have OpenAI-compatible tooling and want a drop-in local endpoint
- you need a Python library for streaming, multi-turn Copilot chats
When to avoid
- you need a production-grade, officially supported API with SLAs
- you cannot accept the risk of violating Microsoft's terms of service
- you need models or features Copilot's web chat does not expose
