I reverse engineered Windows Copilot into a free OpenAI compatible API (GPT-4, no API key, no billing)

A developer has reverse-engineered the Windows Copilot to create an unofficial API that allows users to access GPT-4 without an API key or billing, utilizing their own Microsoft account. The setup exposes a local server at `http://localhost:8000/v1`, enabling compatibility with the OpenAI SDK for streaming and multi-turn conversations, making it a cost-effective solution for lightweight AI workloads and automation. This project offers practitioners a way to leverage GPT-4 capabilities for personal and educational use without incurring costs associated with standard API access.
