100-word summary
OpenAI is buying Astral, the startup behind popular Python tools like uv and Ruff, to supercharge Codex. Terms weren't disclosed. The move signals OpenAI is betting on developer tools as a major revenue stream, not just chat interfaces. Astral's open-source projects will stay supported after the deal closes, pending regulatory approval. The team joins OpenAI to integrate their tooling into Codex workflows. Python runs half the world's data science and web backends. Owning the pipes that speed up Python development means OpenAI could become as embedded in coding as GitHub, capturing developers before they even think about which AI to ask for help.
