Why Scaling Application-Layer AI Evaluations Is Harder Than Model Evals
Shahules786 · x · 2026-09-02
The author highlights a significant maturity gap in evaluation setups between model and application-layer companies, noting that most app teams lack robust evals and realistic simulations.
This gap stems from the inherent difficulty of scaling application evals: every customer alters the task context (ecosystem, tools, data, permissions, workflows). A useful simulation must reflect these differences, yet a scalable solution cannot be rebuilt for every client. This tension defines the core challenge of application-layer evaluation.
