We’re releasing GPT-5-Codex—a version of GPT-5 further optimized for agentic coding in Codex.
It’s now live everywhere you use Codex—in your terminal or IDE, on the web, in GitHub, and in the ChatGPT iOS app.
We’re working on optimizing GPT-5-Codex for use in other agentic coding tools, and will bring it to the API soon.
