What you'll learn

Understand What an AI Simulation Environment Is

See how tasks, tools, state, and scoring become a reusable world for evals and reinforcement learning.

See How Eric Approaches Agent Evals

Learn how Eric’s AI evals experience shapes tasks, traces, and graders that expose where agents fail.

Build a Simulation Environment Live

Turn a real task into tools, test cases, and a grader you can reuse for evals or RL.

Why this topic matters

Better models alone don’t produce reliable agents—the environment determines what you can observe, evaluate, train, and trust. Aman and Eric will explain what simulation environments are, why teams use them for evals and RL, and how to design tasks, tools, state, and grading. Drawing on Eric’s experience leading product at an AI evals company, they’ll turn a real task into a repeatable environment live.
