    Browser Use 如何构建安全可扩展的 Agent 沙箱基础设施

    Browser Use 分享了其 Agent 沙箱架构的演进:从最初在 AWS Lambda 上运行浏览器智能体,到把整个智能体放进沙箱、通过控制平面持有全部凭证的 Pattern 2。生产环境每个智能体运行在独立的 Unikraft micro-VM 中,启动不到一秒,仅接收 SESSION_TOKEN、CONTROL_PLANE_URL 和 SESSION_ID 三个环境变量,本地开发和评测则用同一镜像跑 Docker 容器。控制平面作为无状态 FastAPI 代理,统一处理 LLM 调用、S3 文件同步和计费,代价是每次操作多一次网络跳转。

We provision them via Unikraft Cloud's REST API on dedicated bare metal machines in AWS. The sandbox receives only three env variables from the outside world: SESSION TOKEN, CONTROL PLANE URL, and SESSION ID. No AWS keys, no database credentials, no API tokens. Unikraft gives us scale-to-zero out of the box. When a sandbox is idle, the VM suspends. When the next request comes in, it

    智能体时代该用哪个 AI:模型、应用与 harness 指南

    Ethan Mollick 发布第八版 AI 使用指南,指出使用 AI 已从聊天转向智能体,选型需同时考虑模型、应用和 harness 三层。他给出的三大前沿模型是 GPT-5.2/5.3、Claude Opus 4.6 和 Gemini 3 Pro,并建议做实际工作时手动选择高级模型而非默认的自动模式。他认为模型差距已经缩小,应用与 harness 的差异更关键,Claude Code、Claude Cowork、OpenAI Codex 等工具在工具调用和自主执行上领先,Gemini 网页端在生成文档和引用方面仍较弱。

    堆也会撒谎:调试 vLLM 内存泄漏

    Mistral AI 定位了 vLLM 在 Mistral Medium 3.1、图编译及 Prefill/Decode 分离部署下每分钟增长 400 MB 的内存泄漏,根因是 NIXL 依赖的 UCX 拦截 mmap,并让待清理区域在 RCache 失效队列中累积。设置 UCX_MEM_MMAP_HOOK_MODE=none 可消除泄漏且未影响性能,另可将 UCX_RCACHE_MAX_UNRELEASED 设为 1024;相关修复已合并至 vLLM,UCX 与 NIXL 团队也计划在未来版本中调整行为。

    Anthropic 谈 AI 智能体的有效上下文工程

    Anthropic 应用 AI 团队撰文提出上下文工程,将其视为提示词工程的延续,核心是在 LLM 有限的注意力预算内挑选最小的高信号 token 集合。文章指出随着上下文 token 增多,模型准确召回信息的能力会下降,即上下文衰减,因此系统提示词、工具、示例和消息历史都应保持信息充分而紧凑。针对长周期任务,文章介绍了压缩、结构化笔记和多智能体架构三种绕开上下文窗口限制的做法,并提到 Claude Code 采用即时检索与预加载结合的混合策略。

Beyond storage efficiency, the metadata of these references provides a mechanism to efficiently refine behavior, whether explicitly provided or intuitive.

    把提示词当代码:用 port.md 和 JSON 状态做跨语言代码移植
