Introducing Effective Agent Evals: Best Practices & Methods

The first five chapters of our guide to measuring agents: outcomes, judges, graders, mistakes and the objective function.

Today we are releasing the first five chapters of Effective Agent Evals: Best Practices & Methods, our guide to measuring agents. They cover the fundamentals you need before you can trust a score:

  • Outcomes: what different agents produce, what kind of answer a test can have, and who should grade it.
  • Judges: how to assess the way an agent reached its outcome, and why a correct answer can hide a bad run.
  • Graders: how to choose and test human graders, how LLMs extend them, and why no score reaches 100 percent.
  • Mistakes: how to measure how often each kind of mistake happens and what it costs.
  • Objective function: how to combine all of this into one decision.

We’ll be releasing the remainder of the book as we put it together over the coming weeks and months. Stay tuned.
