Build Reliable and Observable AI Agents with Pydantic AI and DBOS

AI agents have become increasingly capable of autonomously performing tasks such as booking hotels and managing accounts, yet integrating these agents reliably into production software remains a challenge due to their dynamic and brittle nature. To address this, DBOS, a lightweight database-backed execution library, integrates with Pydantic AI to provide fault tolerance, observability, and scheduling for AI agents, ensuring their reliability without the need for an external workflow engine. By checkpointing each step of an agent's workflow in a database, DBOS allows processes to resume from the last completed step after crashes or restarts, avoiding the need to repeat previously completed work. This seamless integration allows for the creation of production-grade, multi-agent systems that maintain reliability and observability, which is exemplified by a multi-agent deep research platform that combines structured agent logic with durable execution. This platform demonstrates how various AI agents can collaborate to plan, execute, and synthesize research tasks, all while ensuring resilience, scalability, and real-time observability.
