Prompt Evaluation Suite

Test, score, and regression-check prompts and model changes before they reach production.

Automated scoring and grading

Datasets built from real traffic

Regression gates in CI

Overview

The Prompt Evaluation Suite brings engineering discipline to prompt and model changes. Build datasets from real traffic, score outputs with rubrics and model graders, and gate deploys on regressions — so a prompt tweak or model swap never quietly degrades quality.

How it works

Build evaluation datasets from real production traffic, score outputs against rubrics or model-based graders, and wire the results into CI as a regression gate. A prompt or model change that fails the gate never reaches production.

What's included

Dataset creation tooling, rubric and model-grader scoring, CI integration for regression gates, and historical trend reporting across every prompt and model version you've shipped.
