Today, AI is rapidly changing the way we build software, and the pace of that change is only accelerating. If our goal is to make programming more productive, then building at the frontier of AI and software feels like the highest-leverage thing we can do.
It is increasingly clear to me that Codex is that frontier. And by bringing Astral’s tooling and expertise to OpenAI, we’re putting ourselves in a position to push it forward. After joining the Codex team, we’ll continue building our open source tools, explore ways they can work more seamlessly with Codex, and expand our reach to think more broadly about the future of software development.



It’s manageable if you pass along these rules to the LLM. I’ve actually had more success asking the LLM than giving code reviews to some interns, and even someone who coded professionally before.
