    HEMA 如何用 MCP 和 Amazon Bedrock 打造内部 AI 助手 HAL

    荷兰零售商 HEMA 基于 Amazon Bedrock AgentCore 构建了内部 AI 助手 HAL,并通过 Model Context Protocol(MCP)把知识接入 HAL 聊天、Kiro、Claude 等工具。HAL 将原本需要三四个门户、耗时一下午的查询缩短到数秒,安全依托 Microsoft Entra ID,客户端不存 AWS 凭证,目前为只读访问。

    Ed Zitron 长文质疑 AI 数据中心产能:大量 GPU 仍堆在仓库

    Ed Zitron 在长文中质疑 AI 数据中心的真实产能,认为微软等超大规模厂商用 gigawatt 这类模糊说法夸大了 AI 算力上线规模。他引用微软约 2.2 million 颗 GPU、约 1.993GW 容量与约 50 billion 美元 GPU 的数据,对比其自 2022 年以来约 265 billion 美元的资本开支,估算有 50 billion 至 100 billion 美元的 GPU 仍在仓库或未通电的数据中心里。他进一步汇总各厂商 construction in progress 数据,推算约 200 billion 至 300 billion 美元的 NVIDIA GPU 是提前数年售出,并认为折旧压力和项目融资债务会放大风险。

Across hyperscalers including Google, Meta, Oracle, Amazon, SpaceX, and Tesla, neoclouds like CoreWeave and IREN, and colocation companies like Core Scientific and Applied Digital, there is over $374 billion in construction in progress, a figure that’s likely lower than the true number, because Amazon’s contribution ($71.7 billion) is only current as of th

    与 Epoch AI 的 JS Denain 辩论 RSI、中美差距与模型能力参差
