Free API keys for top models are now public

A public repository is now offering free API keys for GPT, Claude, Gemini, and Grok models, with no credit card or registration required, targeting students and indie developers for light testing and prototyping. The shared quotas come with rate limit instability, making them unsuitable for production use but convenient for quick comparisons and weekend projects.

Key points

  • A public repository is offering free access to GPT, Claude, Gemini, and Grok API keys. - No credit cards or registration are required to access these shared quotas.
  • The pool is intended for light testing and prototyping rather than production use.

This is a goldmine for students and indie devs who just want to test a prompt or a small feature without jumping through the hoops of international payment methods. While "free" usually comes with a catch, having a rotating pool of high-end models in one place is incredibly convenient for quick iterations.

The big caveat here is stability. Since these are shared quotas, you're essentially playing a game of musical chairs with rate limits. If you're building a commercial app, obviously don't hardcode these into your backend, but for a weekend project or a quick comparison between Gemini and Claude, it's a fantastic resource.
