# OpenAI launches Codex Security Review in research preview

OpenAI released Codex Security Review, a research preview that analyzes GitHub pull requests for security issues using repository context.

- It uses repository context to perform deeper security analysis.
- Automatic review can be enabled via documentation at learn.chatgpt.com/docs/security/security-review.
