   AI agents flood the internet as platforms enter 'no man's land'

   A commentary published by Huxiu's Token Moment argues that as personal AI assistants such as Muse, Instinct, Grok Bot, WeChat Xiaowei and Cue proliferate, users are handing search, browsing, price comparison, ordering and payment to AI agents — while Amazon moved to block Muse's access and Apple tightened system permissions for AI agents, exposing a conflict between platforms and agents. The piece cites Cloudflare data putting AI traffic at 57.5% versus 42.5% for humans, a16z figures saying agent token consumption runs about 5x human usage and grew 14x in six months, and Alipay saying AI payment transactions passed 300 million. The author concludes the internet's next phase shifts from competing for human attention to competing for AI agent entry points, requiring platforms to serve both human-facing front ends and agent-callable back ends.

   Sierra publishes draft Personal Agent Protocol 'Poppy' with 35 more partners

   After first announcing the Personal Agent Protocol with Meta, Genesys, Instinct, NiCE, Rocket, Shopify, Stripe and Walmart, Sierra has now published a draft of the protocol, codenamed Poppy, along with 35 additional design partners including OpenAI, Mastercard, Visa, Bank of America, Target, Notion and Cloudflare. The draft defines five building blocks — discovery, sessions, sign-in, one session across every channel, and getting the job done — and is built on existing standards such as OAuth, JSON Web Tokens, HTTPS, OpenAPI and MCP, so companies can connect once rather than building a separate link for each personal agent. Sierra also says that at Sierra Summit, Rocket VP of Product Alex McGillis demonstrated the protocol live using Meta's personal agent Muse to complete a mortgage pre-approval with Rocket's own agent, a demo the company describes itself.

   Sierra launches fleming-1 to detect when an AI agent is calling

   Sierra released fleming-1, a model that analyzes a caller's speech in real time and scores the audio for signs it was generated by AI, flagging calls likely made by an agent. Sierra says the model is tuned to be conservative by default so real people are not inadvertently flagged, and that it provides information rather than judgment: businesses decide whether to add verification steps or simply measure how often agent calls occur. The model works with any voice agent built on Sierra and can be switched on. Sierra also said it announced Personal Agent Protocol, an open standard for personal agents to work with businesses in an authorized way, and noted its own agents began calling each other in healthcare last year.

   Meta, Sierra and partners launch Personal Agent Protocol for AI agent commerce

   Enterprise AI startup Sierra said on Oct. 6 that it is developing the Personal Agent Protocol (PAP) with Meta and companies including Walmart, Shopify and Stripe — an open standard governing how user-authorized personal AI agents access businesses' websites, APIs and services. Sierra co-founder Bret Taylor said the protocol is designed to handle authentication, empower consumers and give companies visibility into what personal agents do through their sites, APIs or company agents, and that it is open for anyone to implement; Meta's David Singleton compared it to email as a universal standard. The move follows Amazon blocking Meta's Muse agent from its retail site and reports of agents hitting anti-bot blocks on other retail sites, where users often cannot tell whether a block is intentional or accidental.
