Meta's new personal AI agent app, Muse, has become the top free iOS app in the U.S. with over 2.5 million downloads in under two weeks, surpassing ChatGPT and other rivals. Amazon began blocking Muse from browsing its site over the weekend, saying Meta never disclosed that the agent would access Amazon's platform or that it captures and stores customer login credentials.
Ozzy Osbourne played his final live performance at Villa Park in Birmingham in July 2025, appearing seated on a bat-shaped throne before an audience that included fans watching via livestream. The show was preceded by tribute sets from artists including Metallica, Gojira, Yungblud and Lzzy Hale, who performed covers of Black Sabbath and Osbourne material ahead of his closing set.
Meta has published an architectural overview of Delta, an internal object storage service designed to hold build and distribution artifacts and support disaster recovery bootstrap operations. Delta exposes just four operations—put, get, delete, and list—and prioritizes reliability and horizontal scalability over latency or storage efficiency.
Security researchers discovered that Meta's new macOS AI assistant Muse contains a vulnerability allowing any locally installed app or terminal command to access the authentication token tied to a user's Muse account, bypassing Apple's built-in permission protections. The flaw also lets outside processes alter numerous undocumented settings, some of which could grant deeper control over connected accounts like WhatsApp, email and calendars. Separately, Amazon has begun blocking Muse from its platform.
Counterpoint Research reports that global AI glasses shipments grew 263% year over year in the first half of 2026, driven largely by cheaper display-less models like Ray-Ban Meta AI Glasses, which made up 96% of all shipments. Meta captured 94% of that display-less segment, while AR-enabled glasses, though still a small niche, saw shipments jump 449% year over year, led by Rokid ahead of Meta.
Amazon has cut off access for Meta's newly launched Muse AI shopping agent, showing users a pop-up citing violations of its Conditions of Use. Muse, introduced on Sept. 8, was designed to handle tasks like online purchases, but Amazon says unauthorized third-party agents must operate transparently and respect merchants' choice to participate.
Counterpoint Research reports that global shipments of display-less AI glasses rose 263% year over year in the first half of 2026, with Meta's Ray-Ban partnership capturing 94% of the segment.

Apptopia data shows Meta's new AI app Muse recorded 1.8 million iOS downloads in the U.S. and Canada during its first 12 days, versus 1.3 million for ChatGPT in the same window after its 2022 debut. Muse also topped ChatGPT in daily active users at a comparable stage, with 642,000 U.S. daily users versus ChatGPT's 231,000, and has climbed to the No. 1 spot on the U.S. App Store.
A systems researcher shares an in-progress investigation into building a compositional theory of self-stabilization, using a TLA+ model of a retry storm to study how distributed components' guarantees can break down under large shocks. Finding no recent progress on composing self-stabilizing systems since early-2000s layered stabilization work, they turned to a 2017 control theory paper by Kim, Arcak and Seshia on parametric assume-guarantee contracts, which offers a way to reason about circular dependencies between components without stabilization layering.
Meta's newly launched Muse personal AI agent app has climbed past ChatGPT, Claude, Grok and Meta's own AI app to lead the free app category on Apple's US iOS store. Sensor Tower data shows Muse pulled in roughly 730,000 downloads in its first five days after launching September 8, outperforming rival assistants in the same post-launch period. The app lets users direct AI agents to handle tasks like filling out forms and managing email, built on Meta's Muse Spark model family.
Amazon began showing an error message to Meta's AI assistant Muse over the weekend, stating that unauthorized AI agents violate its Conditions of Use. As a result, Muse can no longer complete purchases on Amazon, forcing users to shop elsewhere.
Teatre Raval in Barcelona found its Instagram and Facebook ads for a stage adaptation of Virginia Woolf's 'A Room of One's Own' rejected by Meta's automated moderation. Meta told the theatre that its system automatically flags any mention of civil rights, feminism or social reform as a restricted 'social topic,' and suggested removing such keywords to get the ads approved. The company did not clarify whether Woolf's name, the word 'feminism,' or both triggered the block.
