DailyReport (Deep Research Agents) - Rationality: leaderboard
DailyReport (2026) tests search agents on open-ended daily information-seeking tasks about trending topics; each task is split into subtasks with cascade rubrics for instruction following, factuality and rationality, judged by Gemini 3 Flash. This board is the rationality rubric score in percent for the analytical parts of the report, for native deep research agents; higher is better.
Metric: Rationality (0-1 scaled to %), rubric scores of 0, 0.5 or 1 for logically sound analysis, counted only where the instruction-following rubric holds; open-ended daily search tasks on trending topics decomposed into subtasks with cascade rubrics, judged by Gemini 3 Flash; native deep research agents with built-in search, 1,800-second timeout; higher is better. Source: arxiv.org. Saturation forecast: Rough model projection: around 2026. 5 models tracked.
