The announcement included no numerical benchmark scores, so independent comparison with OpenAI, Anthropic, and Google models is not currently possible. The Muse personal agent app launched September 8. It hit No. 1 on the U.S. App Store and passed five million downloads in 22 days, according to Sensor Tower estimates. Since then, average daily downloads have fallen about 8.1% week over week to roughly 165,000, and net daily user growth has slowed about 62% from late September. TIME reported that Muse builds continuously updated profiles of users, and Meta did not dispute the finding. Hunterbrook Capital, a short seller that took a position against Meta on October 9, has also warned that the agent could be prompted to compile lists of accounts tied to vulnerable groups. No regulatory action specific to this release has been reported. One report cites mounting regulatory scrutiny of Meta's AI push more broadly.
Meta is using a model upgrade to address a visible slowdown in adoption, and retention reportedly trails ChatGPT. Analysts say better benchmarks alone will not fix either the slowdown or the permissions concerns. Attorneys tracking this should watch the profiling and data-permissions issues, since they carry the clearest regulatory exposure. Indicators to watch include independent evaluations, daily active users, paid conversion, and Meta's upcoming quarterly results.
