Meta's personal AI agent, Muse, has seen rapid user growth, with daily active users increasing tenfold to 700,000 in the past 11 days, but server-side pressure has emerged earlier than expected. Alexander Wang, Meta's Chief AI Officer, revealed on September 9 that Muse's early actual usage far exceeded expectations, with user consumption being about 10 times that of the internal testing group. Third-party status monitoring platform SaaSHub has marked Muse as "Degraded," and some users have reported issues such as "unable to search." Additionally, the agent frequently fails when executing complex tasks; in one stress test, Muse attempted to create 120 sub-agents simultaneously but only succeeded in 33. These issues indicate that Muse's actual operational load is significantly higher than early test expectations, and hashrate bottlenecks are gradually surfacing. Muse is currently only available in the United States and Canada, and registration entry has not yet been fully opened on WhatsApp and Instagram.
