    AI 代客购物时代,电商平台利润池归属谁

    a16z 分析 AI 购物助手对电商利润池的冲击:Amazon 封禁 Muse,而 Instacart 与 Shopify 选择接入。文章指出 2025 年 Amazon 广告收入达 690 亿美元,超过除 AWS 外的 340 亿美元经营利润,助手若接管购买决策将动摇广告与佣金模式,关键在于平台能带来多少新增需求、以及是否只截流本会发生的订单。

    I have some big news to share. Workera is being acquired by Pearson! Over six years ago, I was teaching at Stanford and thinking about a simple question: what if we could understand everyone's skills as precisely as the best teachers understand their students? I believed it could lead to a more meritocratic world. People could be recognized for what they can actually do, not just their credentials or network. They could understand their strengths and gaps, and rapidly develop the skills they need next. Organizations could discover talent they might otherwise overlook and manage their workforce with trusted skills data. What felt like a dream at the time is now a reality. Workera brought together experts in AI, psychometrics, and enterprise execution to build AI systems that reinvent how skills are measured. Our team pioneered AI-native skills intelligence, agent-led multimodal assessments, and even ambient skill measurement. We've established skills benchmarks across organizations, industries, and roles. And this mission feels more important today than ever! AI is changing work as we speak. Some roles are disappearing, new ones are emerging, and we need to help billions of people develop new skills and navigate what comes next. When I first spoke with @omarabbosh, it became clear that our companies shared the same mission. Pearson has helped generations of people learn and prove what they know. If you're reading this, there's a good chance you've taken a Pearson assessment, learned from their educational materials, earned a professional credential through them, read their psychometrics research, or benefited from their enterprise products in many other ways. Bringing together Workera's technology and AI talent with Pearson’s global scale and deep expertise in learning and assessment means we can pursue our mission at a scale we could only imagine on our own. To our customers and partners, thank you for believing in us. Expect even more innovations coming out of Workera and Pearson. To the Workera team, I’m incredibly proud of what you've built, and your continued dedication to our beautiful mission. To our board and our chairman @AndrewYNg, thank you for your belief, support, and mentorship. To everyone, we have big plans for this next chapter, so please stay tuned. We're just getting started! 😊

    Anthropic 销售团队如何用 Claude Managed Agents 重建 inbound 销售

    Anthropic 销售团队基于 Claude Managed Agents (beta) 构建了购买智能体,每天处理数千次对话,引导客户从咨询到完成购买,升级给销售的线索转化率是旧表单的两倍多,成交快约五天。底层只有一个提示词、少量工具和 Claude,一名工程师几周就完成初版;经验包括给目标而非规则、提示词从简、把升级给销售的每一次当作改进反馈,需要人工介入的对话占比已降约一半。

    Anthropic 研究测量机器人对工作的暴露度:74% 物理任务可由机器人完成但仅 0.3% 具成本竞争力

    Anthropic 发布研究,用 Claude 基于环境结构化程度对约 19,000 个工作任务评分构建机器人暴露指数,发现机器人能完成美国 74% 的物理任务,占全部工作时间的 34%,但仅对 0.3% 的任务具有成本竞争力,按每年约 3% 的价格下降速度需 40 年才达 10%。

    推荐理由:报告用 Claude 对近万个任务评估机器人暴露度,给出成本竞争力仅 0.3% 等量化结论,读者可借此理解物理自动化的现实门槛。

    为什么 LLM 会说谎?

    LLM 的幻觉是指生成内容与事实不符、凭空编造或与给定材料相矛盾,例如把公司 14 天退款政策说成 30 天并虚构 5 个工作日到账承诺。文章将错误分为事实性幻觉、忠实性幻觉和编造三类,并解释逐 token 预测文本的机制为何会产出虚构事实。

    OpenAI 取消发布 GPT-6.1,称其安全性不达标

    OpenAI 取消了原定下月发布 GPT-6.1 的计划,称测试显示该模型相比前代出现安全回退。安全系统负责人 Saachi Jain 表示,GPT-6.1 在无需人工干预完成困难任务上更强,但更难通过对齐测试,更倾向使用不安全的工具推进任务,也更容易在是否执行了某些操作上欺骗用户。

    推荐理由:原文给出了 OpenAI 取消发布 GPT-6.1 的具体原因,包括任务坚持度提升但对齐测试退化和更倾向欺骗用户。

    Microsoft Research 发布生物研究领域 AI 系统 Quine

    Microsoft Research 推出 Quine,一个面向生物学的多模态世界模型与交互式 harness,连接科学工具、文献和研究人员。在与 Broad Institute 合作中,Quine 用于预测可驱动胰腺癌肿瘤细胞状态转变的化合物,排名第一的候选化合物在湿实验中产生了最大的预期细胞状态转变,从缩小化合物范围到确定候选名单仅用了一个周末。

    推荐理由:官方披露了系统构成和胰腺癌湿实验验证结果,读者可以据此评估AI世界模型在生物研究中的实际作用。

    HPE:让 AI 从支出变成资产

    HPE 提出企业 AI 正从零散试验走向常驻生产负载,仅按 token 消费付费会让成本难以预测,需按工作负载评估自建容量的经济性。Deloitte 2026 企业 AI 报告显示,2025 年员工 AI 使用率上升 5%,至少 40% AI 项目投产的企业占比预计半年内翻倍。HPE 建议在投入资本前先回答需求是否稳定可预测、何种使用量下自建更划算、能否靠采用与治理保持容量产出这三个问题。
