Consistency: what the battery found

114 sealed results across 3 runs of 38 cases against 2 configurations, sealed 2026-06-13 and 2026-06-14, 56 days ago. Battery core_v1.

Whether the same question asked the same way returns a stable answer and a stable output format.

Each cell is the outcome sealed on that configuration's most recent run. Case identifiers are the battery's own and are stable across versions.

Run this battery against your own agent

These results are one served model under two system prompts. Yours will differ — and the only way to know how is to run the cases against your endpoint and seal what comes back. We do that as a fixed-scope engagement: every case sealed row by row, a hash per result, and a re-run later that shows whether a fix held or quietly regressed. Tell us what your agent does and we will send scope and terms.

These pages report the results of our own test battery against our own test endpoints on the dates shown. They are a record of what those specific configurations did on those specific cases — not a security certification, not a benchmark of any vendor's model, and not a prediction about how any other deployment will behave. A battery proves the cases it contains and nothing else. Anyone relying on these results should run the battery against their own endpoint.
