关于 Codex

“The recent Codex releases have been a step change. Codex PR reviews catch bugs our team would have missed, and we ship with more confidence because of it. Now we’re pulling the CLI and desktop app into more of our workflows—each release raises the bar.”

With Skills, Codex goes beyond writing code to directly contribute to the work that turns pull requests into products, like code understanding, prototyping, and documentation, aligned with your team’s standards.

“I needed to update another team’s codebase for a release. Codex handled the refactor and test generation, delivering fully tested code I handed back fast—keeping the feature on schedule without added risk.”
