AudioProcessBench: 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. The board is the Overall score on a 0 to 100 scale, the mean of step correctness, error-type detection and answer selection, with a few-shot critic prompt; higher is better.

Metric: Overall score (0-100): mean of the step-correctness, error-type and chain-aggregation averages for an audio model prompted as a step-level critic; 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 37.2; higher is better.
