美国互联网：持久化消费者AI智能体争夺战打响

Barclays examines the battle for the persistent consumer AI agent space, where Apple, Google, OpenAI, Meta and startups like Instinct have laid out different visions. Winning criteria likely include: 1) trust, 2) low-cost compute, and 3) access to personal connectors, with a prize of upwards of ~$10T in market cap. Persistent consumer agents are likely to be free for end users and funded by a combination of ads and referral fees on transactions. With substantial ad stacks and $300+ in US ARPU, Google and Meta sit in early pole position. The cost of hosting free consumer agents runs about $4/DAU per month at scale with connectors in place, ~10x more expensive than ChatGPT's inference cost per free user of sub-$0.50 per month. Beyond compute cost, the race comes down to trust around security and encryption, and convincing users to connect their agent to the most downstream personalized services. The report also covers the architectures of Meta's Muse, Apple's Siri AI and OpenAI Dots, and
