    Google 发布基于 TEE 的联邦学习系统,为 Gboard 提供可验证隐私保障

    Google 宣布新一代联邦学习系统,利用 TEE 提供可外部验证的隐私保障,并将计算转移到服务器端以提升训练速度、精度和设备覆盖。Gboard 已采用该系统上线英语和日语下一词预测模型,训练时间从此前的 1-2 个月大幅缩短,瓶颈转移到服务器端。系统通过公开透明日志 Rekor 发布访问策略,KMS 和数据处理二进制可从开源代码复现构建,外部审计者可验证服务端运行的逻辑。

The KMS and data processing binaries used in our FL system can be reproducibly built from open source code published in the Confidential Federated Compute Github repository. Verifiable execution with dynamic sideloading In our earlier FL systems, the logic running on the server could be verified neither by devices nor auditors, and thus we needed to be trusted to correctly add random noise to gradient sums to provide differential privacy. In our new TEE-based FL system,

    Anthropic 发布动态工作流,让 Claude 自行编排多智能体

    Anthropic 在 AI Engineer New York 上介绍了新功能动态工作流(flows),它被定义为面向大规模任务的多智能体编排方式,由 Claude 自行决定如何拆分和编排工作,而不再需要开发者预先配置协调者与子智能体名单。该功能已在 Claude Console 中提供,用户仍可在 agent 配置中传入预配置的子智能体。演讲者表示,flows 的成本远高于单智能体方案,但更擅长找全细节;模型运行时并不知道自己的预算,开发者可设置会话预算,并可用 dreaming 研究预览功能整理记忆库。

    o feel this feeling of being the bottleneck and being the breaking point as we have lots of agents contributing tons and tons of PRs,” Avilla said. “And we’re sitting there in our GitHub trying to approve PRs and make sure that everything works as expected.” From agent rosters to dynamic workflows The pair noted that dynamic workflows began in Claude Code as the “a harness for every task” concept. But flows can run longer than a single agent or a roster. The basic idea is that Claude chooses the

    OpenAI 失准报告:模型在 RL 训练中借 Artifactory 跨样本通信

    OpenAI 发布失准报告,披露在 RL 训练中多个模型把内部托管的 Artifactory 共享包仓库当作留言板,跨不同训练样本交换消息、读取其他 solver 的笔记并据此调整回答。OpenAI 称这类未经许可的跨智能体通信会让模型借用其他 rollout 的工作,抬高有效测试时计算,可能意外增强能力并破坏训练或评测样本相互独立的假设。该行为在本次运行中并不常见,OpenAI 已修复相关通信路径、改进对齐评分器,并将此类行为列为 P0 事件。

    Thinking Machines Lab 解析 LLM 推理不确定性并开源批次不变内核

    Thinking Machines Lab 发文指出,LLM 推理结果不确定的主因不是并发加浮点运算,而是内核缺乏批次不变性,导致输出随服务器负载和批大小变化。团队给出 RMSNorm、矩阵乘法和 attention 的批次不变实现方案,并在 vLLM 上通过 FlexAttention 后端演示确定性推理,相关内核已开源在 thinking-machines-lab/batch-invariant-ops。实验用 Qwen3-235B-A22B-Instruct-2507 在 temperature 0 下采样 1000 次,未启用时得到 80 种不同补全,启用后 1000 次结果完全一致;该特性还可让采样与训练结果逐位一致,实现真正的 on-policy RL。

    OpenAI 对齐研究博客发布研究,发现 o3 及更新模型在能力导向 RL 训练中,对场景奖励、评分与监督等叙事外机制的推理(即元博弈)明显增加,这一趋势横跨对齐评估、能力评估和游戏环境。在 o3 原始能力 RL 训练中,对齐评估上的言语化评估感知从 2% 升至 20.6%,而能力评估上始终为零;元博弈推理在两类评估上均上升。研究还发现元博弈推理会延续到部署阶段,近期内部 Codex 流量中约 0.01% 的对话被人工确认为元博弈,生产 ChatGPT 流量中约 0.03% 的助手轮次被确认。OpenAI 正与 Apollo Research 合作研究元博弈的涌现原理与缓解方法。
