Hamel Husain & Shreya Shankar Share Their Playbook for Building AI Eval Systems
HamelHusain · x · 2026-09-23
Hamel Husain and Shreya Shankar published a guide in Lenny's Newsletter on building eval systems that actually improve AI products, distilled from training 2,000+ engineers and PMs including teams at OpenAI and Anthropic. Key points: use error analysis to find where your AI product breaks; build evals you can trust instead of vanity dashboards; and create a continuous improvement flywheel that catches regressions before they ship. The methodology underpins their Maven course AI Evals for Engineers & PMs, the platform's top-grossing course.
