Introducing Py AI: Community Events for Python AI Builders

We're thrilled to announce that Prefect and Pydantic are partnering together to launch Py AI, a community for Python developers shipping AI to production.

The hard part was never getting a demo to run. It was everything after: reliability at scale, iteration without regression, the thousand small fires that ignite the moment real users show up. We built Pydantic, Pydantic AI, Logfire, Prefect, and FastMCP—tools that millions of developers use to ship. So when we say the hard part isn't the demo, it's everything after, we're not guessing. We hear it every day.

Py AI started because we wanted a room where those conversations could finally happen. This joint initiative combines Prefect's expertise in workflow orchestration and distributed systems with Pydantic's leadership in Python data validation and AI tooling. Each event will feature lightning talks, live demonstrations, and networking opportunities—the kind of authentic conversations that emerge when practitioners come together in person.

Events

We're starting with meetups in San Francisco, New York, and London, with a larger conference planned for early 2026.

San Francisco - November 11th

Hosted by Pebblebed on November 11th, 5-8pm PST.

Teams from Reducto & Modal discussing document processing with distributed Python infrastructure
Adam Azzam - Co-founder & CTO at FastMCP on orchestrating AI workflows and MCP
Michael Moore - from SentinelOne on writing quality MCP using coding assistants

After the presentations, we'll have open discussion and networking time.

New York - November 21st

Py AI Conference — Early 2026

Details coming soon. Call for proposals will open shortly. Subscribe to our Luma calendar for updates.

This partnership between Prefect and Pydantic reflects our shared commitment to supporting the Python AI community. Py AI is a community for practitioners who ship, and who care about systems that keep working after the first release.

We curate sessions where you walk out with something to try tomorrow. That means clear stories, concrete tradeoffs, and details that hold up when you push back. No hype. No merchants of complexity. Just builders comparing notes.

We're eager to hear from developers across the ecosystem. Whether you're working with MCP, distributed infrastructure, or simply trying to ship something that works, these events are designed for you. Join us to connect, learn, and share what you tried, what broke, and what you'd do differently.

FAQ

Who should attend?

Python developers shipping AI to production—those building with AI frameworks, working on agentic systems, or integrating LLMs into real applications. If you've ever shipped something that looked great in a notebook, then spent weeks making it not fall over, these events are for you. If you're working with tools like Pydantic, MCP, LangChain, or distributed compute infrastructure, you'll find your people here.

What's the format?

Each event (except the conference) runs for around 2 to 3 hours with 4 or 5 lightning talks (10-15 minutes each), followed by open networking. We curate sessions where you walk out with something to try tomorrow. Talks focus on practical implementation details, concrete tradeoffs, and ideas you can actually use—not high-level theory. Practitioners, not evangelists.

Do I need to prepare anything?

No preparation required. Bring questions about your current projects if you want specific feedback during networking sessions.

Is there a cost?

All events are free. Registration is required due to venue capacity.

Will talks be recorded?

Events will not be recorded and attendance is in-person only.

Can I propose a talk?

Not for these initial meetups. The February conference will have an open call for proposals. Subscribe to our Luma calendar for updates.

What if I can't make it in person?

If you have signed up and cannot make it to the event, please withdraw your registration as spaces are limited. If you want to join, but you're not in town, subscribe to our Luma calendar to learn about future event announcements.
