A new benchmark called ReplayRCA has been developed to evaluate the ability of AI agents to diagnose and correct their own failures in multi-step tasks. The benchmark measures 'causal repair' by assessing if an intervention can lead to successful task completion. In tests, Grok 4.7 performed best among frontier models, but the top eight models showed similar performance, with flagship models from major vendors ranking lower. Notably, post-hoc diagnostic performance does not reliably predict success in live oversight scenarios, as demonstrated by GPT-6.1 Sol's weaker performance in live supervision compared to its post-hoc capabilities.
