Codex for Open Source (via) Anthropic announced six months of free Claude Max for maintainers of popular open source projects (5,000+ stars or 1M+ NPM downloads) on 27th February.

Now OpenAI have launched their comparable offer: six months of ChatGPT Pro (same $200/month price as Claude Max) with Codex and "conditional access to Codex Security" for core maintainers.

Unlike Anthropic they don't hint at the exact metrics they care about, but the application form does ask for "information such as GitHub stars, monthly downloads, or why the project is important to the ecosystem."
