Pydantic

@brandonbellero @pydantic Cooked. I left untyped Python in the Dark Ages where it belongs. Production infrastructure demands type safety, not medieval guesswork.

“medieval tools like mallets and untyped python” @pydantic absolutely cooked in their ai docs

Samuel Colvin (@samuelcolvin) is joining us at PyCon Italia 2026 to show why most AI frameworks are trapped in the "chat paradigm", and how durable execution + Pydantic AI + Temporal lets agents survive failures and pick up exactly where they left off! 2026.pycon.it/event/durable-…

PyAI panel discussion OSS in the age of AI: youtube.com/watch?v=7WkGWQ…

"If someone confronts you with 10,000 lines of code, I find it real hard to believe that those are the right 10,000 lines of code." — Guido van Rossum The problem isn't AI. @lais_bsc wrote a summary of the panel discussion. pydantic.dev/articles/pyai-…

In SF today? Come and join us with @samuelcolvin @tobiemh and 250 data & ai practitioners for casual chat about agent in production today at AWS loft! Super excited! @cocoindex_io @pydantic @SurrealDB

4 of many sessions coming to Replay 2026 👀 San Francisco May 5-7 - @amasad from @Replit - @dkundel from @OpenAI - @samuelcolvin from @pydantic - Catherine Zhang from @blocks replay.temporal.io

I'll skip the workshop but will be at the PyAI meetup at the end of the day. See yas there, folks.

April 8th is going to be a long one. @samuelcolvin is running a 2h workshop at @aiDotEngineer, then we're straight into a PyAI meetup at the @atomico office in London. Come find us!

The meetup is full, but add yourself to the waitlist and we'll squeeze in as many as we can. Fair warning: it might be a cozy one. luma.com/fkkiar5m?utm_s…

best time ever for open-source legends to build a company trained your whole life to sell software at 0% GMs and still make money somehow

Meet pydantic-deep, an open-source framework for building production-grade "deep agents" on Pydantic AI. pydantic.dev/articles/pydan… youtu.be/AhV5DqiHn7E

Look at me casually seating next to the creator of Python, Guido van Rossum, as if it was normal 🤩

Pydantic AI version 1.70.0 is out! 🎉 github.com/pydantic/pydan…

PyAI was such a success and I think it's because it was unapologetically by builders, for builders. We wanted to create a conference that we'd actually want to attend, and I think the team absolutely crushed it. It wasn't a vendor conference; it sure as hell wasn't PrefectCon. It was just the best possible place to learn from folks on the cutting edge of the technologies you use every day. See (way more of) you next year.

@pydantic @adtyavrdhn03 Good post — was just telling someone today how I’m so used to visualizing a codebase, and am slowly losing touch with the codebases I wrote myself (not to mention the ones I started with an agent)

I have been harboring these thoughts for a while now and it was great to pen it down.

Another great highlights video from PyAI.
