BrainBench (EEG) - CodeAct - Neurocognitive Assessment: leaderboard
BrainBench (arXiv 2608.04156v2, Table 1) score on the Neurocognitive Assessment subset built on cognitive-experiment EEG, with each model running through the free-form CodeAct Python execution loop in an isolated container and its report and artifacts checked by task validators. 0-100; higher is better. Optional reasoning modes disabled.
Metric: EEG analysis score (0-100). Source: arxiv.org. Saturation forecast: Around November 2027. 13 models tracked.
