AI Evaluations Crash Course in 50 Minutes (2025) | Hamel Husain

Author: Peter Yang September 28, 2025 Duration: 52:29

Today, I want to share a new episode with Hamel Husain.


Hamel has trained 2,000+ PMs and engineers from companies like OpenAI, Anthropic, and Google on how to run AI evals. In my new episode, he shares a free master class on how to build evals for a real AI agent in just 50 minutes using a simple spreadsheet. I learned a lot from Hamel and I think you will too.


Hamel and I talked about:

(00:00) What the most valuable part of evals is

(01:25) Live walkthrough: Analyzing 100 real production traces

(09:50) Creating the eval criteria using a simple spreadsheet

(24:44) Why binary pass/fail ratings beat 1-5 scores every time

(28:52) The agreement metric trap that fools most PMs

(30:08) True positive and negative rates explained

(36:00) How to set up continuous evals in production
