    xAI 发布 Grok Bot 设计说明,以持久化智能体取代会话式交互

    xAI 发布 Grok Bot 的设计说明,将产品主对象从聊天会话改为持久存在的 Bot,每个 Bot 拥有独立身份、记忆、运行时和工具。界面围绕 Bot、Chat、Prompt、Tool、Artifact 五个概念组织,工具与技能放在账户层,记忆与 Routine 归属具体 Bot,账户上限约 50 个 Bot、群聊中 6 个。Bot 头像同时承担身份与状态显示,其独立计算机提供状态、预览和接管三级访问方式。

    . The disappearing interface By the end of the project, much of the design work involved taking things away. We removed window and panel controls, computer-view options, and agent metadata. We also set practical limits of roughly 50 Bots per account and six per group chat. Each decision came back to the same question: Did this help someone delegate, or did it give them one more thing to manage? The line between operating an AI and delegating to a coworker keeps moving as models improve. Grok Bot

    超大规模厂商如何将 AI 泡沫“超常态化”

    Ed Zitron 将 AI 泡沫描述为一种“超常态化”现象,认为科技媒体、资本市场和超大规模云厂商用投资额、估值及年化收入等增长信号替代了对盈利能力与真实需求的检验。他以 OpenAI、Anthropic、Cognition、CoreWeave 和 NVIDIA 为例,质疑未明确定义的 run rate、客户高度集中及循环投资如何共同维持行业繁荣叙事。文章进一步认为,AI 数据中心建设被默认等同于进步,但其商业回报、需求来源和社会成本缺少同等力度的审视。
