Model Evaluation

Model evaluation turns broad claims about an AI system into measurements that can be inspected. It includes testing, validation and verification, but the right evidence depends on the task, the users, the operating conditions and the consequences of being wrong.

NIST’s TEVV programme describes test, evaluation, validation and verification as activities that help assess the trustworthiness of AI systems.¹ The programme’s framing is a useful reminder that evaluation is not just a leaderboard exercise: it is part of establishing whether a system is fit for a particular setting.

Reading results in context

Benchmarks can make comparisons repeatable, but they also embody choices about tasks, data, metrics and reporting. A score alone therefore cannot establish fitness for every use case; that conclusion is an inference from the fact that measurements are tied to their stated conditions.

The HELM project proposed a broad evaluation framework for language models that reports multiple scenarios and metrics, with attention to transparency in how results are produced and presented.²

What this topic covers

This hub covers benchmark design, task-specific testing, robustness, red-team evaluation, human assessment, reporting practices and the limits of generalising from a measured result.
