# Rescore a comparison eval run

POST

/v1/eval-runs/{runId}/rescore

```sh
curl --request POST \
  --url https://example.com/v1/eval-runs/2489E9AD-2EE2-8E00-8EC9-32D5F69181C0/rescore \
  --header 'Authorization: Bearer <token>' \
  --header 'Content-Type: application/json' \
  --data '{ "projectId": "example" }'
```

Starts a new comparison eval run of the same test set version, candidate and settings that replays nothing: it scores the run’s replays again, with the judgments recorded on them since (a changed answer judged on the replay itself; `changes.new` lists the items to judge). The run rescored stays as it was; the new one names it (`comparison.rescoreOf`, `summary.rescoreOf`). A case whose replays can’t be read again keeps its scores (`rescored: false`). Needs `admin` on the run’s suite and `write` on its project.
