Step-by-step guide to getting your open-source project supported by OpenAI Codex for Open Source. I just applied and got approved on the same day. OpenAI offers 6 months of ChatGPT Pro + Codex + API credits for open-source maintainers. As long as you're a core maintainer of a public repository, you can apply. The key question on the application form is 'Why does this repository qualify,' with a 500-character limit. Just clearly explain your project data, technical focus, and how you plan to use Codex. According to the official statement, even if you think you're not fully qualified, you can still apply as long as your project is valuable. Open-source friends, don't miss out!
