Verdict
Quality matched on 29 of 30 cases (83% to 100% at 95% confidence). A switch needs at least 90% at 95% confidence, so the next run's 30 new cases will be combined with these.

Status
The experiment finished and its verdict is available.
Controlled replay compares both models from the same worker. Production latency is shown separately as context and is not subtracted from candidate replay latency.
Latency not tested
This run did not have one explicit funding path that could execute both the source and candidate replay legs. Its quality and cost evidence remains valid.
The evaluation compares structured content canonically and reports presentation adherence as separate evidence unless strict formatting is enabled for the feature.
This run's encrypted evidence expires at the date shown above, 14 days after the run was created. The verdict summary and savings estimate remain in experiment history after that run-specific evidence is deleted.
Review the case results before opening sensitive prompt and response evidence. Opening a case is audited.
