An AI evaluation platform centralizes datasets, test cases, evaluators, rubrics, experiment runs and results. Teams can use it to compare models, prompts, agent harnesses and skills against the same versioned criteria.
A platform helps evaluation become a repeatable engineering practice rather than an isolated demonstration. Useful systems preserve provenance, support human review, expose regressions and connect production feedback to new tests.

An evaluation platform is a shared system for organizing and running AI tests. It stores test cases, scoring rules, model or prompt versions, results, and review evidence in one place.
For example, a team can compare two agent versions against the same customer-support cases and see which failures changed. Keeping the tests and versions together makes the comparison repeatable rather than a one-time demonstration.
