Codex for Open Source
Open-source maintainers can apply for API credits, six months of ChatGPT Pro with Codex, and Codex Security.
Open-source maintainers do critical work, often behind the scenes, to keep the software ecosystem healthy. Over the past year, the Codex Open Source Fund ($1 million) has supported projects that need API credits, including teams using Codex to power GitHub pull request workflows. OpenAI is grateful to the maintainers who keep that work moving.
The fund now supports eligible maintainers by offering six months of ChatGPT Pro with Codex and conditional access to Codex Security for core maintainers with write access. Developers should code in the tools they prefer, whether thats Codex, OpenCode, Cline, pi, OpenClaw, or something else, and this program supports that work.
What the program includes
Six months of ChatGPT Pro with Codex for day-to-day coding, triage, review, and maintainer workflows
Conditional access to Codex Security for repositories that need deeper security coverage
API credits through the Codex Open Source Fund for projects that use Codex in pull request review, maintainer automation, release workflows, or other core OSS work
Who should apply
If youre a core maintainer or run a widely used public project, apply. If your project doesnt fit the criteria but it plays an important role in the ecosystem, apply anyway and explain why.
By submitting an application, you agree to the Codex for Open Source Program Terms.
Given GPT-5.4s capabilities, the team reviews Codex Security access case by case to ensure these workflows get the care and diligence they require.
