本周三条 AI 新闻：代理购物、Claude Duet、DeepSeek 下架
采购顾问视角：沃尔玛 11 月起允许个人 AI 代理下单并设消费上限，Anthropic 推出会主动发消息的 Claude Duet，美国要求联邦机构移除 DeepSeek。
The 3 AI news that caught my eye this week (Week 43 of 2026) Three stories on agents that buy, agents that act first, and AI suppliers you may have to remove: 🛒 Walmart will let personal AI agents shop on Walmart and Sam's Club from November. Agent Profiles set a spending cap, keep AI orders separate and require purchase approval by default. Amazon blocks such agents. Buying by agent is arriving. Set caps and approval rules before your buyers ask. 🤖 Anthropic launched Claude Duet, a research preview of an agent that messages you first. It sends a morning brief, checks your apps every few hours and asks before it sends messages or makes payments. Meta has Muse and OpenAI has Dots. Decide now which actions an agent may take alone. 🚫 The US ordered most civilian federal agencies to remove DeepSeek, including any technology built on its models. Platforms like Snowflake, Vercel and OpenRouter offer DeepSeek models. Ask every software supplier which AI models sit inside their product. Which of these three would change your next AI contract? #AI #FutureOfWork #DigitalTransformation #Innovation #AIAgents #Procurement About the Author: Oscar — Procurement Transformation Builder | IT Vendor Lead | Ex-IBM · Sony · Vodafone · QIAGEN · Huawei · Richemont | Both sides of the table: Buy + Sell | +$300M portfolios | Independent Advisor · AI · AI Agent indie developer | Bringing Procurement from the back-office to the front-office
