Eval

Plain-English explanation

Evals include common cases, edge cases, expected answers, scoring criteria, and regression checks. They are essential for production AI.

Why it matters

Eval matters because it affects how AI systems are designed, evaluated, priced, or trusted. Knowing the term helps you ask better questions and avoid vague implementation decisions.

• Ask how it changes quality, cost, speed, or safety.
• Look for concrete examples in the workflow you are building.
• Document the tradeoff before choosing a tool or architecture.
