AudioProcessBench - Majority Voting Selection: leaderboard
AudioProcessBench (2026) tests audio and omni-modal models as critics of audio-grounded reasoning: given an audio question and a model-written reasoning chain split into steps, the critic marks each step correct or wrong; 3,872 annotated chains from MMAR, MMSU and MMAU-Pro questions. This board sums the chain scores of the critic for each candidate answer and reports the accuracy of the chosen answer in percent; higher is better.
Metric: Final-answer accuracy (%) when the critic's chain scores are summed per candidate answer; 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; random 40.6; higher is better.
