OpenAI acquires Astral. Why the creators of ChatGPT needed ruff and uv

OpenAI is taking over Charlie Marsh's team — the creators of uv and ruff. The very folks who rewrote half of Python's tooling in Rust.

The official press release is heavily doused with corporate syrup about "expanding Codex capabilities" and "synergy with open source."

Translating into human language 🥸

LLMs have long been able to decently generate snippets. But OpenAI doesn't need smart autocompletions — they need full-fledged autonomous AI agents (read: digital mid-level developers). An agent can't just spit out text — it needs to set up a virtual environment, resolve dependencies, run linters, catch bugs, and fix them in a loop.

If you make an AI agent automatically call standard pip and slow Python checkers thousands of times, the process will simply stall.

Astral's tools (uv, ruff, ty) work at the speed of light. For OpenAI, this is not charity but the purchase of a perfect, deterministic, and ultra-fast execution engine. On its basis, their networks will code, test, and build projects without human intervention. Charlie Marsh simply built the perfect pipeline for them, for which he rightfully got his payout.

Officially, of course, we are promised that the tools will forever remain open, free, and independent. Yeah, right, screenshot this 🌚
