NVIDIA Vera Rubin NVL72 能效提升最高30倍
NVIDIA 公布早期实测数据显示,Vera Rubin NVL72 在智能体工作负载下的每兆瓦吞吐量较 GB300 NVL72 最高提升30倍,单位百万 token 成本最高降低35倍。当前结果尚未反映 Vera CPU 的工具调用性能,且有待 SemiAnalysis 复核。

新型AI模型Ox Alpha被OpenRouter标注为"隐身模型",由匿名第三方开发,定位为面向代码编写与生产负载的推理模型,日前在OpenRouter免费上线。其身份引发猜测,有观点指向中国GLM模型,也有人怀疑是微软MAI的未发布版本,各方说法分歧较大。
Inherent 是一家由 Google DeepMind 校友于伦敦创立的 AI 实验室,该公司表示其 27B 参数的 AI 智能体 Faraday 在复现研究论文这一任务上,性能超过了 Anthropic 的 Claude Opus 4.8 和 OpenAI 的 GPT-5.5。据 arXiv 论文和公司研究博客介绍,Faraday 通过长视界强化学习训练,使用自有 Replica 任务套件(取自 100 篇机器学习及 AI for science 论文的 310 项任务),在无法访问原图的情况下完成论文复现。Faraday 运行在规模相对较小的 Qwen 3.6 模型之上,与更大的前沿模型相比参数仅 27B。目前该成果仍是公司自我报告,未经独立验证;Inherent 首席科学家 Edward Hughes 表示,关键在于建法本身。
哈佛商学院为企业创始人开设的八周、699美元HBS Foundry创业营,引入了由HeyGen制作的导师AI数字分身,用于在练习路演和董事会会议中提供个人反馈,每周仍保留真人导师直播课。项目主管Katharina Rings表示,最初设想的是聊天机器人,发布试用版后学员希望获得更引导式的体验。纽约时报记者Sarah Kessler实测后称,路演时AI版Flybridge Capital联创Jeff Bussgang呈现明显的僵硬笑容;Bussgang坦言自己的数字副本有点「creepy」,但表示「我的学生很喜欢它」。
Meta Superintelligence Labs has released Muse Glimmer, an open-weight agentic model that anyone can download and run on their own hardware. The company open-sourced the model weights under the permissive Apache 2.0 license, and the 30-billion-parameter model is now available on Hugging Face as meta-models/Muse-Glimmer-30B. Muse Glimmer is optimized for always-on local agent workflows and is described as small enough to run on a Mac or PC with a single consumer GPU. The model card notes it is distilled from Muse Spark and includes a perception encoder, with 4-bit quantization shrinking it to under 20 GB so it fits within 24 GB or 32 GB VRAM envelopes, including on Nvidia RTX 5090 and Apple M4/M5 Max. Developers can get started immediately through the Ollama library by running "ollama run muse-glimmer," which enables fully local use without cloud or network access. No pricing or hardware-requirement changes accompany the release, and no limits beyond typical GPU memory constraints have been detailed. The Apache 2.0 license means builders can freely use, modify, and distribute the weights for commercial applications. Since the model is released as open weights, teams can deploy always-on local agents on their own infrastructure, with the main uncertainty being real-world throughput and memory performance on individual consumer-grade hardware setups.
