What changed

Added

lattis/evals-action, a first-party GitHub Action that runs your eval suite on every pull request.

Changed

Pull request checks now show the suite score, the threshold and the three lowest-scoring cases inline.

Action needed

Add the action to your workflow and set a threshold. Suites without a threshold report scores but never fail the build.

Release notes

The new lattis/evals-action runs your eval suite on every pull request and fails the check when a change scores below your threshold.

The action wraps the Lattis CLI, so the same check runs in GitLab CI, CircleCI, Buildkite or any runner that can call a command.

- uses: lattis/evals-action@v1 with: threshold: 0.90
