Alexandr Wang Enthusiastically Promotes Meta's Muse, Sparking Consumer AI Buzz

From September 18-20, Alexandr Wang, founder of Scale AI and Meta's Chief AI Officer, posted and reposted heavily to promote Meta's newly launched Muse product and thank the research team behind it, drawing wide attention in AI circles. Praise focused on Muse's highly configurable feed and agent productivity, including users claiming they abandoned Google search for Muse Agent; however, most material consists of reposts and subjective impressions, with no first-hand product specs.

Confirmed

• On September 18, Wang published a long post thanking the Meta Superintelligence Labs (MSL) research team behind Muse, calling the underlying model "the most underrated part" and naming researchers in agentic post-training, tooling, and computer use.
• He reposted Alex Klarfeld's praise that Muse is the most impressive, most configurable feed he has seen, capable of ingesting Twitter timelines, deployment statuses, meeting schedules, and news; he also reposted a user's experience post, commenting on how much work Muse can take on.
• He amplified "Muse has risen" with "MUSE MADNESS 🔥🔥🔥" and said on September 20 that "muse madness taking over the nation"; he replied to a user (@atbeme) who found Muse smoother and more polished than grok bot.
• On September 20, he reposted five Muse use cases: personalized ad-free feeds, online form filling, comparison shopping (e.g., license renewal), and other task automation.
• On September 19, podcaster Joe Carlson called Muse genuinely good and was surprised Meta shipped it before Google, Anthropic, and OpenAI, predicting others would follow; Wang replied they had been planning this for a long time. The same day, a user claimed to have stopped using Google's AI Mode after adopting Muse Agent, arguing Meta may have won consumer AI; Wang reposted it.

Unconfirmed

• All material is reposts and subjective praise; Muse's concrete feature specs and rollout scope lack first-hand details.
• "Meta has won consumer AI" is one user's opinion, and Carlson's prediction of competitors following suit remains speculation.

Why it matters

• Wang's dual role at Scale AI and Meta's superintelligence lab makes his sustained endorsement a signal of Meta's internal prioritization of Muse; his thanks to the MSL model team also reveals that the model layer is seen internally as Muse's core.
• Carlson's remarks and Wang's "long-planned" reply frame Muse as Meta's opening move in consumer AI, raising pressure on rivals.
• If the "agents replacing search" behavior becomes a trend, it could threaten Google's position as the information-retrieval entry point and reshape the consumer AI landscape.
