OpenAI is acquiring Python developer toolmaker Astral, thus bringing open source developer tools into OpenAI’s Codex AI coding system. The acquisition was announced on March 19. Elaborating on the deal, OpenAI said Astral has built widely used open source Python tools, helping developers move faster with modern tools such as uv, Ruff, and ty. These tools power millions of developer workflows and have become part of the foundation of modern Python development, OpenAI said.
By bringing in Astral’s tools and engineering expertise, OpenAI said it will accelerate work on Codex and expand what AI can do across the software development life cycle. OpenAI’s goal with the Codex ecosystem is to move beyond AI that simply generates code and toward systems that can participate in the entire development workflow, helping plan changes, modify codebases, run tools, verify results, and maintain software over time. Astral’s developer tools sit in that workflow. With the integration of these systems with Codex, OpenAI said it will enable AI agents to work more directly with the tools developers already rely on every day.
Python, OpenAI said, has become one of the most important languages in modern software development, powering everything from AI and data science to back-end systems and developer infrastructure. Astral’s open source tools play a key role in that ecosystem, OpenAI said. These tools and their capabilities are cited in OpenAI’s announcement:
