AuthAI is an open-source relay that allows end users to pay for AI features using their existing ChatGPT, Grok, or GitHub Copilot subscriptions via OAuth. It enables app builders to integrate AI functionality without managing API costs, using a secure token relay architecture that encrypts OAuth tokens with per-record AES keys. The project is interesting for its novel approach to delegating AI costs to users while maintaining a familiar OpenAI SDK interface.

Target audience: backend devs
