Foundry evaluation editor

What this editor does

A Foundry evaluation runs quality/safety/accuracy evaluators against a dataset plus a model deployment, surfacing metric tables and pass/fail signals. In Loom it is wired to the Foundry BFF route.

Getting started

  1. Pick a dataset — Select the test dataset to evaluate against.
  2. Choose evaluators — Add built-in evaluators (groundedness, relevance, fluency) plus any custom ones.
  3. Run the evaluation — Run against the model deployment to produce metric tables.
  4. Read pass/fail — Review pass/fail signals to decide whether to promote the deployment.
