Live demo: running agent code with Agent Sandboxes in Pydantic Logfire

Samuel Colvin connects an agent to Agent Sandboxes in Pydantic Logfire, has it call your own tools from the code it writes, and traces every run. Thirty minutes, with the last part kept for your questions.

Watch Samuel Colvin run the code an agent writes in Agent Sandboxes, live, then bring your questions.

About this event

Agents work better when they write a short script to call your tools. That script still has to run somewhere, and a whole container or VM is a lot of machine for ten lines of code.

Join Samuel Colvin, creator of Pydantic, for a live walkthrough of Agent Sandboxes in Pydantic Logfire: a sandbox for the code your agent writes. Not a container or VM. An isolated interpreter written in Rust, powered by Pydantic Monty, our open-source interpreter.

Engineers and platform teams building agents inside a product, especially agents that call many tools or work with large tool results.

Every Logfire plan includes 50,000 free Agent Sandboxes invocations a month. Sign up to follow along.

A 30-minute session, including live Q&A.

What you'll learn

  • Why code mode changes what agents need to run
  • A live demo: connecting an agent, calling your own tools, and seeing every run traced in Logfire
  • What the code your agent writes can and can't reach
  • Live Q&A
