In a move clearly designed to strengthen its position among developers, OpenAI has acquired Python tool maker Astral. The house of Altman expects the deal to strengthen the ecosystem for its Codex programming agent.
Since its founding in 2022 by Charlie Marsh, Astral has won over a substantial portion of the Python community with Rust-based tools like uv (package and project manager), Ruff (linting and formatting), and ty (type checker) that outperform Python-based tools like pip.
OpenAI says that it plans to continue supporting these tools as open source projects while using them internally to improve Codex and make AI more useful as part of the software development lifecycle.

"Our goal with Codex 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," the company said in a [2]blog post .
[3]
[4]
"Astral's developer tools sit directly in that workflow. By integrating these systems with Codex after closing, we will enable AI agents to work more directly with the tools developers already rely on every day."
If Astral's tools can make AI-generated code more maintainable, that would be a significant win. One of the [5]emerging concerns about the shift toward AI-generated code is that it's more difficult to maintain.
[6]
The deal also looks to be an acquisition of talent. According to OpenAI, the Astral team will join those working on Codex in an effort to make the coding agent more adept.

OpenAI's acquisition of Astral follows rival Anthropic's December 2025 [11]purchase of Bun , a runtime, package manager, test runner, and bundler for JavaScript/TypeScript applications.
In a [12]blog post on Thursday, software developer Simon Willison remarked that the two deals have occurred amid intense competition between OpenAI and Anthropic.
"Bun was already a core component of Claude Code and that acquisition looked to mainly be about ensuring that a crucial dependency stayed actively maintained," he wrote. "Claude Code's performance has increased significantly since then thanks to the efforts of Bun's Jarred Sumner.
"One bad version of this deal would be if OpenAI start using their ownership of uv as leverage in their competition with Anthropic."
[13]
But Willison also suggests a possible motive for the deal unrelated to competitive leverage. He points out that [14]Marsh's post about the deal thanks investors who committed to Series A and Series B funding rounds. Those investors, he speculates, should now be able to exchange their stake in Astral for a stake in OpenAI, which reportedly could [15]go public as soon as the end of this year. ®
