AI Researcher Elvis Omarsar: Learn to Build Evals or You Can't Improve Anything

omarsar0 · x · 2026-11-01

Elvis Omarsar (omarsar0) argues that building proper evals is the core skill for improving anything — a model, a complex codebase, or a business function. He notes that AI today excels mostly at verifiable problems precisely because measurement there is tractable, while the open-ended real world demands a fundamentally different approach. He is also preparing a survey on the current state of evals and soliciting questions from readers.
