Astral Joins OpenAI: The Interview talkpython.fm/episodes/show/… OpenAI acquired Astral, the team behind uv, Ruff, and ty. So what actually happens to the tools a lot of the Python world now depends on? With @charliermarsh and @mkennedy

When the deal was announced, the loudest reaction I saw was some version of "is uv toast?" It's a fair question. These tools became core infrastructure fast, and people are right to care where they're headed.

So I sat down with Charlie Marsh, the founder of Astral, now leading the same team inside OpenAI on the Codex group, to ask directly. A few things that stood out:

1. The counterintuitive part: Charlie thinks they may ship more open source at OpenAI than they did at Astral, not less. As a venture-backed company, the work had to stay coupled to a commercial vision. That pressure is off now.

2. What stays the same: he looked at the data, and the release cadence held steady before, during, and after the acquisition. uv, Ruff, and ty are still the priority, and ty is still on track for a stable release this year.

3. pyx, their hosted registry, is winding down - but the hard GPU/CUDA wheel work is being open-sourced rather than kept behind a product.

4. His take on trust: you don't convince skeptics with a press release, you convince them with actions over time.

We also get into what it's like to build developer tools inside a frontier lab, and why working well with coding agents is a real skill you have to learn, including the rough patch coming to terms with agentic coding.
