（来源：PaperWeekly） NeurIPS 2025 刚刚在圣地亚哥落下帷幕。 作为全球 AI 领域的风向标，今年的 OpenReview 数据比往年更具冲击力。5825 篇接收论文刷新了历史记录，但如果只看数字，你可能会错过今年最本质 的变化。 结合 AI World 的两份深度报告以及我们挖掘的全量数据，一个清晰的新秩序浮出水面。 中美双极格局固化，LLM 的单纯架构红利正在边际递减，强化学习与具身智能全面接管赛场。 而最残酷的真相是：学术界与工业界的界限已被打破，算力与人才的深度绑定，成为了通往 SOTA 的唯一门票。 榜首易主：全量反超与头部博弈 今年数据的最大看点，在于全量和头部两个维度的反差。大多数人只盯着 Top 50 榜单看，觉得 Google 还是稳坐榜首。但如果把范围拉大到所有机构，清 华其实已经在总量上拿到了第一。 这两张图，说明了两个完全不同的问题。 1. 全量总榜 首先看包含所有长尾机构的全量统计（All）。中国高校靠着庞大的科研规模，在数量上压过了工业界巨头。 | Tsinghua | | University of Chinese ... | | Beijing .. | ...

RT phil beisel (@pbeisel)Running OptimusThe latest Optimus running demo is a bigger deal than it looks. The bot isn’t just speeding up its walk; it’s executing a legitimate human-style jog, somewhere in the 4–8 mph range. And the motion quality is what stands out— smooth foot placement, natural cadence, stable torso control. It’s copying the dynamics of a human runner far better than most expected at this stage.The hardware is obviously carrying a lot of the load. Multiple high-precision actuators are coord ...
