OpenAI says CodeRabbit uses Codex and GPT-6 Astra to review AI-generated code and ship far more software.

OpenAI published a customer story on November 9 about CodeRabbit, which uses OpenAI models and Codex to review and govern AI-generated code. CEO Harjot Gill says Codex let the same team ship about 20 times more software over six months, and he estimates he opened 2,500 to 3,000 pull requests in 30 days. He estimated GPT-6 Astra caught about half of known issues in CodeRabbit's internal review benchmark. CodeRabbit says it is used by more than 20,000 organizations and 150,000-plus open-source projects. CodeRabbit Secure uses Daybreak with Codex models to find and fix vulnerabilities, and a Codex-powered Slack bot can return a pull request for incident triage.
