Hamel Husain interviews benhylak on using simulations for agent evals
HamelHusain · x · 2026-10-11
Hamel Husain's AI Evals course features an interview with benhylak on implementing simulations for agent evals at multiple companies. Key topics: why input/output tests miss agent failures, replaying production traces, recreating data and tools around agents, 'simulation awareness' (models detecting they're in a simulation and changing behavior), choosing targeted scenarios, checking answers/costs/tool behavior across runs, replaying known failures to verify fixes, and common mistakes that make simulations misleading.
