    OpenWorker 发布新版本,内置面向安全流程的智能体

    开源智能体 OpenWorker 发布新版本,内置三类网络安全智能体,分别用于扫描代码漏洞、扫描依赖中的供应链注入以及检查云安全配置中的攻击面,让开发者在部署前完成更多安全工作。OpenWorker 的 harness 完全开源,安全团队可审计其是否会把代码和数据外传;模型可自选,既能完全本地运行开放权重模型,也可使用 ChatGPT 订阅、Ox Alpha 等预览模型或任意 API key 接入。Andrew Ng 表示该工具与 @rohitcprasad 合作推进。

    OpenWorker -- an open source agent that doesn't just chat but completes tasks on your laptop -- just released a new version with many features for security workflows. After our initial release, many users found it especially useful for cybersecurity. Attackers are already using AI; OpenWorker is committed to giving defenders the same leverage. Running an agent requires both (i) A model and (ii) A harness (the software around the model). Because the OpenWorker harness is fully open source, securi

    NVIDIA Groq 3 LPX 在 Vera Rubin 上实现长上下文超快交互

    NVIDIA 发布面向 Vera Rubin 平台的交互式 AI 推理加速器 Groq 3 LPX,Artificial Analysis 在 100K 上下文下用 Gemma 4 31B 实测中位输出速度为 3,431 tokens/秒,10K 上下文下为 3,382 tokens/秒。该加速器采用确定性执行模型,由编译器预先调度芯片间通信并细粒度重叠计算与通信,可与 Vera Rubin NVL72 组合用于 prefill-decode 分离、attention-FFN 分离和外部草稿模型投机解码等配置。在 SPEED-Bench 编码基准上,同一系统用 Gemma 4 达到中位 4,767 tokens/秒、P80 为 5,520 tokens/秒。

    LPX, measuring a world-class interactivity of 3,431 output tokens/second. The technologies that power this performance unlock the ability of the Vera Rubin platform to serve multiagent systems powered by 2T+ parameter models with high interactivity and long context, through pairing Groq 3 LPX with Vera Rubin NVL72. Agentic sessions are characterized by multiturn inference. At the end of each turn, the agent’s output is appended to the continually growing context that is fed into all subsequent

    SGLang 推出 Weight Cache Daemon,引擎重启权重加载从 495 秒降至 0.63 秒

    SGLang 发布 Weight Cache Daemon,这是一个常驻 GPU 进程,把量化后的模型权重留在显存中,通过 CUDA IPC 零拷贝映射给新的引擎实例。基于 Ling-2.6-1T FP8 模型,权重加载从约 495 秒降到约 0.63 秒,端到端启动时间从 8.8 分钟降到 0.528 分钟,减少 93.9%。该组件是 Fast Engine Recovery Framework 的第一阶段,目标是把冷重启压到 10 秒以内、热备切换压到 1 秒以内,目前支持 TP+PP、单机与多机启动,以及未量化和 block-wise FP8。
