Astral, a company that builds tools for Python development, has announced that it will be joining OpenAI as part of the Codex team. The acquisition will allow Astral to continue building its open-source tools, including Ruff, uv, and ty, and explore ways to integrate them with Codex. OpenAI will continue to support Astral's open-source tools after the deal closes. The goal of the acquisition is to make programming more productive by building tools that feel fast, robust, intuitive, and integrated.
