Here's how to build durable AI agents with Pydantic and Temporal

What this post added

Introduces native Temporal support in Pydantic AI, allowing AI agents to leverage Temporal's durable execution for fault tolerance, long-running interactions, and state preservation. This integration automatically wraps non-deterministic agent work (LLM calls, tool executions) as Temporal Activities with built-in retries, while the agent's coordination logic runs as a deterministic Temporal Workflow. Demonstrates this with a two-agent system for a Slack dinner recommendation bot, showcasing orchestration, handling asynchronous messages with Signals, coordinating API calls as Activities, and implementing human-in-the-loop approval flows.
