Some personal (very belated*) news, I've moved to the bay area!

Let me know if you're in SF or Palo Alto and want to get coffee.

Also, last reminder that we have the inaugural Py AI meetup with @pydantic.dev in SF on Tuesday. Register now: luma.com/gjtfecc7

* I actually got here in the summer.

I added two new demos showing durable agent patterns (parallel vs sequential) with @pydantic.dev AI + @dbos.dev:

- Deep Research: large fan-out parallel workflows
- Twenty Questions: long sequential subagent chaining

Both are long-running, so durable execution is necessary to survive crashes.

I wrote a tutorial on integrating DBOS with Logfire. It's super easy to set up (kudos to the @pydantic.dev team!) -> just a few lines to configure the exporter and your Logfire write token. Once it's running, you'll get a unified view of your app with logs + traces in one place.

Several people (thanks to @mitsuhiko.at and @sa.muelcolvin.com) noted early on that DBOS had too many dependencies. In the latest Python release, we trimmed it down to just 6 direct deps while still implementing durable workflows and queues in one library.

It's lightweight (for real).

I think this might be MASSIVE:

Pydantic AI is getting support for @vercel.com AI Elements streaming, making it easy to build React or Next.js frontends for Pydantic AI agents.

Video demo in the PR:

Vercel AI Elements types by samuelcolvin · Pull Request #2923 · pydantic/pydantic-ai
This adds support for Vercel AI Elements streams to Pydantic AI. There's an example frontend in a separate repo github.com/pydantic/pydantic-ai-chat the plan is to either make that into a more ...

@pydantic.dev AI 🤝 Temporal

Together, run durable agents that:

✅Survive API failures & app restarts
✅Handle long-running & async tasks
✅ Preserve progress with replay-based fault tolerance

Production-grade resilience for agents.

Played around with @logfire.pydantic.dev from @pydantic.dev during today's Python+AI office hours. Took just a couple minutes to set up and start seeing traces from agent calls!

ICYMI, #Heroku support for @pydantic.dev is here.

To get started, all you have to do is provision Managed Inference and Agents from Heroku Elements or via the command line.
