Anthropic会成为人类历史上最值钱的公司吗？ Anthropic于2026年10月26日向SEC递交S-1招股书，预计募资超千亿美元、估值2万亿美元；Menlo Ventures调查显示Claude在企业AI决策人中的份额达54%。
据钛媒体报道Menlo Ventures调查于2025年末进行，覆盖全美495名能决定企业模型选用、额度与付费的AI决策人。按IPO估值计算，Anthropic发售阶段市值将超过上市超10年的工商银行和阿里巴巴发售价。若上市后涨幅超200%，其市值将超越英伟达2025年10月29日盘中峰值5.37万亿美元。

英伟达团队基于 MiniMax H3 开源视频增强方案，最高支持 4K 重生成 英伟达与MIT团队在Hugging Face发布Open-H3-Regenerate-2K模型权重，基于MiniMax H3将低分辨率视频重生成至2560×1440，最高支持3840×2160原生4K；仅训练细化LoRA，配合LightX2V等适配器三步去噪。
据量子位报道配套推理代码已在NVlabs/Sana仓库开放。MiniMax H3完整系统含多模态上下文处理、基础音视频生成和高分辨率重生成；已开放权重的H3-Base生成768P音视频，官方H3-Regenerate-2K模块通过API提供服务。训练时保持H3 Transformer主干与视频VAE参数不变，仅训练新增细化LoRA。
开源视频增强可自部署，利好视频生成团队

OpenAI又出数学大结果，陶哲轩：数学不该被AI“掠夺式开采” OpenAI公布数学、计算机科学和物理学三项新发现，称手稿为待理解的原始研究材料；人类数学协会已有1008位成员，其中654人加入承诺不用AI的“无AI研究小组”，陶哲轩呼吁数学家停止与OpenAI合作。
据钛媒体报道三项发现于10月26日公布，OpenAI未将其包装为定论，而称手稿为待进一步理解的原始研究材料，邀请外部专家组织团队核查解释。此前10月初OpenAI曾一次性发布722份AI生成数学手稿。AHM名单显示1008位成员中654人加入“无AI研究小组”，承诺不发表AI生成论文、不与前沿实验室合作、研究不使用AI。

超节点火了一年后，“算力不够就加机器”的扩张逻辑正在被改写 超节点成为AI算力基础设施焦点，通过NVLink/CXL等高带宽互连将数百至上千颗AI芯片整合为统一计算单元，规模从英伟达GB200 NVL72的72卡到华为及国产厂商的384卡、1024卡级，直指大模型训练的数据搬运与跨芯片同步瓶颈。
据InfoQ 中文报道超节点通过紧耦合互联与软硬协同，将芯片整合为统一计算单元，直面大模型训练中的数据搬运、跨芯片同步与内存利用率低等瓶颈。NVLink/CXL等高带宽互连是低时延通信的基础，软硬协同设计决定性能增益是否匹配硬件规模扩张。厂商展示算力实力的方式，从拥有多少GPU、建设多大规模集群，转向能连接多少颗芯片协同工作。

一天造300万个沙盒，10万张卡自己写系统：2026年国产 RSI 到底有多野？ 雷锋网梳理国内RSI（AI造AI）进展：上海交大、清华、字节、商汤等35位研究者论文将RSI分L1至L5，称全球前沿系统多在L1-L2过渡；智谱是国内首个把RSI跑进生产环境的案例，但目前无厂商用AI改写底层模型权重。
据雷锋网报道该论文题为《The Last AI Built by Humans》，由35位研究者完成，将RSI分为L1至L5五层，指出L3、L4仅在软件工程、科学发现等垂直领域有零星雏形，L5闭环仅存在于极少数受限实验室原型。国内厂商晒出的成果覆盖训练流程、推理系统、GPU算子、Agent脚手架，但均未用AI改写底层模型权重。

TRAE 开发者个人助理，打响 AI Coding 的下半场 TRAE推出开发者个人助理，针对AI Coding中提示词编写、IDE手动修改、终端测试与文档切换造成的上下文断裂，试图打通任务调度、状态管理与验证闭环；文中提及Meta个人助理Muse上线两周登顶美加iOS免费榜、下载量340万。
据极客公园报道TRAE指出，单点开发任务即使提速五到十倍，项目从需求到交付的速度未必能有两倍提升。每切换应用或开启新会话，都需重新说明项目内容、设计原因、修改进度与遗留问题。2026年OpenAI、Google、字节、腾讯、阿里均在加速落地个人助理类产品，短期内上百玩家入场。
