Huxiu puts consumer-agent serving costs at US$1-5 per user per day

Chinese practitioner discussion moves the agent race from launch buzz to unit economics, protocol rails and who captures the transaction.

What happenedHuxiu's Silicon Valley 101 discussion says Meta and Sierra are co-developing the Personal Agent Protocol with Instinct, Shopify, Stripe and Walmart. It estimates Muse and Instinct each cost roughly US$1-5 per user per day to serve, and frames independent agents such as Instinct as taking a cut of completed transactions.

Why it mattersThe estimate puts a hard constraint on "free" consumer agents: scale only works if transaction revenue, subscriptions or platform support catch up. The protocol point puts Instinct at the standards table, but the cost number is not a company disclosure.

Evidence limitsThe full discussion text was checked through the matching 海外独角兽 discussion text on Woshipm; Huxiu's own page confirmed the title, author and exact 6:00 pm China-time stamp. The piece is Chinese-language, and its trust contrast is a single attributed user anecdote.
