After the deal closes, OpenAI will continue supporting our open source tools, and we'll keep building in the open -- for the Python ecosystem -- just as we have from the start.

We've entered into an agreement to join OpenAI as part of the Codex team.
I'm incredibly proud of the work we've done so far, incredibly grateful to everyone that's supported us, and incredibly excited to keep building tools that make programming feel different.

ran on all files in my codebase.
pyright: 5 seconds
ty: instant
i'm convinced

Announcing the Beta release of ty: an extremely fast type checker and language server for Python, written in Rust. We now use ty exclusively in our own projects and are ready to recommend it to motivated users. 10x, 50x, even 100x faster than existing type checkers and LSPs.

We are so incredibly excited to see ty in beta!
@astral_sh ships quality tools.

ty was our most technically-challenging project yet.
There are so many people to thank: our contributors, members of the Python typing community, the Salsa team, the Elixir team (whose work strongly influenced our approach to gradual types and intersections), and more.

On a longer time horizon, though, ty will power semantic capabilities across the Astral toolchain: dead code elimination, unused dependency detection, SemVer-compatible upgrade enforcement, CVE reachability analysis, type-aware linting, and more.

We want to make Python the most productive programming ecosystem on Earth.
Just as with Ruff and uv, our commitment from here is that ty will get significantly better every week by working closely with our users.

And as always, such a privilege to be part of this incredible team x.com/charliermarsh/…

But above all I want to thank our core team: @AlexWaygood, @sharkdp86, @carljm, @DhruvManilawala, @dcreager, @Gankra_, @burntsushi5, @ibraheemdev, @oconnor663, and Micha Reiser. You created ty from nothing and pushed it to be great from Day 1.

So, so hyped that this release is finally out!
It was a huge amount of effort to get this over the line. There's still so much more to do but we're so excited for more folks to try it out and tell us what you think 😃

ty also includes a best-in-class diagnostic system, inspired by the Rust compiler's own world-class error messages.
A single ty diagnostic can pull in context from multiple files at once to explain not only what's wrong, but why (and, often, how to fix it).

This year, we managed to ship Python 3.14 support for uv and Ruff on the day of the stable release. A big lift from the whole team.
We wrote up a guide on some of our favorite features from 3.14, and how they affect our tools.

As of Python 3.14, the free-threaded (or no-GIL) version of the Python interpreter is no longer considered experimental.

🐍 Python 3.14 is here! 🎉
✨ Template strings (t-strings)
🚀 Free-threaded Python officially supported
🎨 Syntax highlighting in the REPL
📦 Zstandard compression in stdlib
🔍 Remote PDB debugging

We're continuing our commitment to the Open Source Pledge this year, projecting another $44,000 in open source sponsorship from the Astral OSS Fund to maintainers / projects we respect, depend on, and learn from.

We've been using pyx at fal and honestly, it's been incredible. No more late nights debugging CUDA versions or PyTorch incompatibilities, it just manages it. Our ML engineers actually thanked me for bringing this one and saving them tens of hours😅

Today, we're announcing our first hosted infrastructure product: pyx, a Python-native package registry. We think of pyx as an optimized backend for uv: it’s a package registry, but it also solves problems that go beyond the scope of a traditional "package registry".

Astral (the VC-backed company behind the popular open source Python tools uv, ruff and ty) have unveiled the first hints at their business model today - a private package registry for companies that use Python

pyx is not yet generally available -- we're a small team, iterating on the product with early partners.
If you're interested in the future of Python, if these problems resonate with you, or even if you're just a fan of our work: get in touch today 👇👇👇
