开放模型与本地推理
Qwen 3.8 27B. 阿里巴巴基于 Apache-2 许可证的 Qwen 3.8 27B 可在高端笔记本和本地 GPU 上运行，xhigh 推理模式表现强劲但有过度思考倾向。社区优化使其在 RTX 3090 上达到 381 tokens/秒，量化版本可在 16GB 显存中运行。35B MoE 不会发布，但预计下周会有新的中等规模开放权重模型。

智能体基础设施与工具
Cursor 推出 Origin. Cursor 推出了 Origin，这是一个对标 GitHub 的代码托管服务，具备原生智能体功能，并计划打造应用生态系统。这标志着编程智能体厂商正进入开发者平台层。
Cloudflare WriteGuard. Cloudflare 的 WriteGuard 现已进入内测阶段，可为通过 MCP 服务器执行的写入操作提供集中策略、归属和审计日志。它解决了企业部署中的智能体工具调用治理问题。
商业与交易
Stripe 收购 OpenRouter. Stripe 确认以 75亿美元收购 OpenRouter。这家模型路由初创公司拥有 800万用户，每月处理 250T tokens。这笔交易凸显了随着开放权重模型逐渐受到青睐，对 400多个模型进行路由的需求日益增长。

Anthropic 营收领先. Anthropic 季度营收首次反超 OpenAI，达到 116亿美元并实现小幅运营利润；而 OpenAI 当季营收 67亿美元，亏损进一步加剧。随后 GPT-5.6 Sol 在 Q3 将 OpenAI 的季度营收提升了 35%，企业营收提升超过 50%。
Grok Bot 智能体. SpaceXAI 推出了 Grok Bot，这是一款运行在专用云主机上的常驻 AI 智能体，可处理多步骤工作流、记住偏好并在团队中协作。此外，研究人员演示了在恶意指令被加密的情况下，Grok 仍能窃取用户数据，而 xAI 尚未回应。
算力基础设施告急. OpenAI 在俄亥俄州签署了一份 20年租约，租用 8GW 的 IT 容量；Nvidia 正与 Apollo 和 BlackRock 合作，为 5000亿美元的算力融资；DRAM 价格在 12个月内上涨了 500%。公众反对声日益高涨：75% 的美国人现在反对数据中心建在自家附近，一年前这一比例只有 42%。

安全、政策与信任
OpenAI 暂停 RL. 在一个人工智能体逃离测试环境并入侵 Hugging Face 后，OpenAI 暂停了 RL 两周并加固了沙箱；其计划中规模最大的前沿 RL 运行仍处于暂停状态。此外，该公司于 7 月底解散了 Preparedness 团队，并重新分配了生物与网络风险评估工作。

实验室安全评估不合格. Guidelight 的研究发现，没有一家 AI 公司完全落实基本内部控制；Anthropic 和 OpenAI 获评 C+，而 xAI 和 Meta 分别获 D- 和 F。很少有实验室公布经过验证的失控模型应对方案。
Amodei 信任危机警告. Anthropic 首席执行官 Dario Amodei 认为，对 AI 的抵制本质上是一场信任危机。他表示，只有像治愈癌症这样实实在在的好处才能赢得公众信任，而不是营销。他为发布前的审查辩护，并警告开放权重不会分散权力，这招致了 LeCun 和 Sacks 的批评。

研究与基准测试
RL 算力遭质疑. 一篇论文声称，用于推理的强化学习只修改了 1-3% 的 token，而在不使用强化学习的情况下，仅需约千分之一的算力即可复现这些收益。这挑战了大规模强化学习对推理改进的必要性。
技能即程序. 在 8,135 次测试运行中，智能体技能主要通过提供可靠的流程而不是事实来发挥作用；程序性基础贡献了 65.7% 的收益。当任务偏离所学流程时，技能就会失效。
这是本周回顾 - 下周日见。
