    Nvidia 的表外担保版图:赢了我赚,输的是谁?

    SemiAnalysis 分析 Nvidia 截至 2Q F1/27 披露的 5300 亿美元表外担保,较上季度的 1840 亿美元大幅上升,主要来自供应与产能承诺从 1190 亿增至 2790 亿美元、为 SB Energy 俄亥俄 PORTS-Pike 园区提供的 1085 亿美元担保,以及首次出现的 360 亿美元 AI 云协议和 200 亿美元数据中心租约。文章认为 Nvidia 通过为 Neocloud 兜底收入、担保房东或直接签约,让非投资级运营商以投资级价格融资,其风险收益在资产负债表保持强劲时是不对称的。按作者统计,Nvidia 目前为约 6.5 GW 容量提供担保,并估算 CY24 至 CY29 的 AI 累计资本开支约 11 万亿美元。

    AI 研究者激辩:递归自我改进离我们还有多远

    Dwarkesh Patel 播客新一期邀请 John Schulman、Beren Millidge 和 Charlie O'Neill 讨论递归自我改进(RSI)还有多远。Beren Millidge 认为最可能的阻碍是持续的 sim-to-real 差距和元学习泛化难题,John Schulman 则指出模型能力提升仍受判断力与自我检查瓶颈限制,难以带来爆炸式增长。

    OpenAI 用 1 万智能体解出 Navier-Stokes,数学家为何愤怒

    OpenAI 宣布用 1 万个智能体组成的集群解出了千禧年难题 Navier-Stokes,成为 AI 首次解出该类问题。但就在宣布前一晚,NYU 数学家 Tristan Buckmaster 与 Anthropic 员工 Levent Alpöge 已发布三篇共约 245 页的相关论文草稿,并公开指责 OpenAI 抢发。作者认为,OpenAI 花数百万美元算力抢先于学术研究者,破坏了数学界开放协作的规范,而 Terence Tao 也指出该结果对流体力学实际应用意义有限。
