GPT-5.5

Mean reward

95.3%

All trials

Across 10 trials on this task, reward ran from 80% to 100% — 7 of 10 cleared every check.

  • 14.3 / 15avg checks passed
  • 11avg turns
  • 12avg tool calls
  • 2mavg time

Summary · GPT-5.5

GPT-5.5 passed 7 of 10 trials. Failures cluster on cp_bug_lockout_count (2/10 trials).

Common pattern

No single verifier breaks every unsuccessful trial — failures move across 4 verifiers, so what varies between trials matters as much as the model.

Why they broke

Most of GPT-5.5's failures on this task were classified as Wrong answer — 3 verifiers across 3 of 10 trials.
