BrainBench (EEG) - CodeAct - Overall: leaderboard
BrainBench (arXiv 2608.04156v2, Table 1): LLMs analyse real EEG recordings from 17 datasets (172 tasks) through the free-form CodeAct Python execution loop in isolated containers and write reports checked by numerical, categorical, semantic and artifact validators. Overall score across four subsets, 0-100; higher is better. Optional reasoning modes disabled.
Metric: Difficulty-weighted EEG analysis score (0-100). Source: arxiv.org. Saturation forecast: Around February 2027. 13 models tracked.
