OpenAI o4-proto-3 achieves closed-loop self-correction on 100+ cycle software debugging tasks
o4-proto-3 demonstrates fully autonomous debugging loop: reads failing test output → hypothesizes root cause → proposes patch → applies patch → re-runs suite → repeats up to 100+ cycles without human input. Reaches 74.2% resolution on internal multi-file, multi-day bug reproduction suite.
