OpenAI has acquired Astral, the company behind popular Rust-based Python tools uv, Ruff, and ty. The deal aims to strengthen OpenAI's Codex coding agent by integrating developer tooling directly into AI-assisted workflows. OpenAI says it will keep Astral's tools open source while using them internally. The acquisition mirrors Anthropic's December 2025 purchase of Bun to support Claude Code. Observers note competitive tensions between the two AI labs, with some concern that OpenAI could use ownership of uv as leverage against Anthropic. The deal is also seen as a talent acquisition and potentially a financial maneuver ahead of OpenAI's anticipated IPO.
