    Block 开源 AI 编码智能体 Goose,对标 Claude Code 且完全免费

    Block 推出的开源 AI 编码智能体 Goose 提供与 Claude Code 相近的功能,但可完全在本地运行,无需订阅费、无速率限制。Goose 在 GitHub 上已获得超过 26,100 颗星,有 362 名贡献者和 102 个版本,最新版本 1.20.1 于 1 月 19 日发布。它支持任意 LLM,可通过 Ollama 搭配 Qwen 2.5 等开源模型本地运行,并集成 MCP 连接外部服务;代价是模型质量、上下文窗口和速度仍不及 Claude 4.5 Opus 等商业方案。

    只是生成描述应该发生什么的文本,而是会实际执行这些操作。 这一能力在很大程度上取决于底层语言模型。根据伯克利函数调用排行榜(该榜单按模型将自然语言请求转化为可执行代码和系统命令的能力进行排名),Anthropic 的 Claude 4 模型目前在工具调用方面表现最佳。 但较新的开源模型正在快速追赶。Goose 的文档重点介绍了几个具有强大工具调用支持的选项:Meta 的 Llama 系列、阿里巴巴的 Qwen 模型、Google 的 Gemma 变体,以及 DeepSeek 以推理为核心的架构。 该工具还与模型上下文协议(Model Context Protocol,简称 MCP)集成,这是一种将 AI 智能体连接到外部服务的新兴标准。通过 MCP,Goose 可以访问数据库、搜索引擎、文件系统和第三方 API——将其能力远远扩展到基础语言模型所能提供的范围之外。 对于有兴趣搭建完全免费、保护隐私的配置的开发者来说,这个过程涉及三个主要组件:Goose 本身、Ollama(一款用于在本地运行开源模型的工具)以及一个兼容的语言模型。 第 1 步:安装 Ollama Ollama 是一个开

    SGLang 推出 EPD 分离架构,为视觉语言模型提供弹性编码器扩容

    LMSYS 在 SGLang 中推出 Encoder-Prefill-Decode(EPD)分离架构,将视觉编码从语言处理中拆出,编码器可独立横向扩容,并支持 ZMQ、Mooncake 等传输后端与视觉嵌入向量缓存。在 8× H20、Qwen2.5-VL-72B、每请求约 4 张 1080p 图像的测试中,图像密集场景下 1 QPS 时 TTFT 比同机部署低约 6–8 倍,0.8–1.0 QPS 吞吐约翻倍;图像较少的场景则可能因跨节点传输嵌入向量而变慢。

    Anthropic 发布 Agent Skills,用文件夹为 Claude 装载领域技能

    Anthropic 推出 Agent Skills,把指令、脚本和资源组织成文件夹,让 Claude 按需动态加载以完成特定任务,目前已支持 Claude.ai、Claude Code、Claude Agent SDK 和 Claude Developer Platform。技能以 SKILL.md 为核心,启动时只预载 name 和 description 元数据,Claude 判断相关后再读取完整内容,并可进一步按需读取目录内捆绑的 reference.md、forms.md 等文件,实现三级渐进披露。文中以 PDF 技能为例,说明技能可捆绑 Python 脚本供 Claude 直接执行,并给出从评测出发、按规模拆分文件、从 Claude 视角迭代等编写建议,同时提醒只从可信来源安装技能。

E.g. to use Meta’s Gloo across the public internet, a common - but theoretically unnecessary and practically slower - solution is to use a VPN.
