Claude Opus 5.5: PCB evaluation status

Claude Opus 5.5 is listed in the October 1 evaluation roster. Comparable measured Season 1 results are not ready, so this page does not publish a score, rank, or cost claim.

The pilot snapshot separates completed attempts, interrupted runs and task revisions. A partial average should not be compared with a model that attempted a different mix of tasks.
