OneMillion-Bench (CN) - Expert Score: leaderboard
Metric: Expert score (%): per task, the weighted share of expert-written rubric points earned (rubric weights from -20 to 10, negative rubrics penalizing violations; each task clipped to 0-1), averaged over tasks on the 200-task CN set (Chinese-context tasks; Finance, Law, Healthcare, Industry and Natural Science, 40 tasks each) of OneMillion-Bench's expert-curated professional tasks, vanilla models without tools (deep-research agents search by design and the paper prints the same result in both settings); rubrics graded by an LLM judge; higher is better. Source: arxiv.org. Saturation forecast: Around July 2028. 19 models tracked.
