Core Insights - Google's research challenges the long-held belief that longer reasoning chains in large models lead to better inference quality, introducing a new metric called Deep Thinking Ratio (DTR) to assess true cognitive depth rather than mere token count [1][3][9]. Group 1: Research Findings - The study found a negative correlation of -0.54 between token length and accuracy across various models, indicating that longer reasoning chains can lead to misdirection and overthinking [3][5]. - DTR measures the proportion of "deep thinking tokens" in a generated sequence, with a higher ratio indicating a focus on core reasoning rather than unnecessary content [8][10]. Group 2: Implementation of DTR - Google introduced the Think@n strategy, which allows models like GPT-OSS and DeepSeek-R1 to maintain accuracy while halving computational costs by filtering out low-quality samples early in the reasoning process [2][12]. - In tests, the Think@n strategy achieved an accuracy of 94.7% for GPT-OSS-120B-medium on the AIME 2025 dataset, surpassing traditional methods, while reducing token consumption from 355.6k to 181.9k [12][13]. Group 3: Implications for Model Development - The findings suggest a shift in focus for model developers from merely increasing token length to enhancing the quality of reasoning, emphasizing the importance of deep cognitive processing [1][19]. - The research highlights the potential for significant cost savings and efficiency improvements in model inference through the application of DTR and the Think@n strategy [9][12].

"我们的电网设备老化严重。它永远无法承受那样的极端数字——即所需要的天量级别电量规模。所以 我在告诉他们，他们可以自己建电厂。他们将自己发电，自行单独用电。这将确保公司获得足够电力的 能力，同时也会降低你们的电价，"他表示。 他没有点名涉及哪些科技或者电力基础设施相关公司，也没有说明该计划将如何实施或如何执行。有媒 体报道称，白宫预计将在3月初邀请相关公司，正式落实这项重大举措。 智通财经APP获悉，美国总统唐纳德·特朗普表示，在他所称美国政府新近谈妥的"电价缴费者保护承 诺"(rate protection pledge)之下，建设超大规模人工智能数据中心的美国科技巨头们将不得不自行承担其 电力需求以及相关费用。特朗普在向国会发表国情咨文演讲时表示，科技企业们将被政府要求为其不断 扩张的AI基础设施版图建设专用级别的电力供应系统，而不是从地方电网额外取电以及大幅增加负 荷。 特朗普在国情咨文中抛出的消费者电力费率保护承诺，本质上是在把AI数据中心新增负荷的"成本归 因"重新写进政策框架，大型科技公司要么自建/自备电源类大型基础设施(on-site / behind-the-meter generation) ...
