AudioProcessBench - All-Error Identification: leaderboard

Metric: PRMScore (0-100) of the binary correctness judgment on every step (balancing detection of erroneous and correct steps); 3,872 reasoning traces (23,497 steps, 41% erroneous) from six audio and omni models on MMAR, MMSU and MMAU-Pro questions, steps labelled by two LLM annotators with human review; few-shot critic prompt with three annotated example chains, temperature 0.7; higher is better. Source: arxiv.org. Saturation forecast: Around October 2027. 11 models tracked.
