## Why it is here

Meta's official launch video for Muse Wonder and Muse Wonder Full (Oct 12, 2026).

## Description (written by Gemini from the video)

**Summary**  
This is the official launch video from Meta announcing Muse Wonder, their frontier-class AI model built for agentic workflows and personal superintelligence. The presentation is led by Chief AI Officer Alexandr Wang, alongside Meta AI research scientists and product managers explaining the model's capabilities and architecture.

**What is shown**  
* **[00:12]** Alexandr Wang introduces Muse Wonder as Meta's largest and most capable model to date.  
* **[00:51]** Motion graphic animation depicting the concept of "active memory," showing interconnected node clusters that represent long-term user preferences and conversational history.  
* **[01:12]** Abstract geometric animation illustrating "active focus," navigating around barriers to represent problem-solving perseverance.  
* **[01:57]** Motion graphic layout visualizing an agent workflow: aggregating real estate listings, tracking calendar dates, maps, and drafting communications to property owners.  
* **[02:17]** Alexandr Wang outlines platform availability across developer and consumer tools.

**Claims & numbers**  
* Alexandr Wang states Muse Wonder is Meta's "largest and strongest model yet" and a "frontier-class model" that "leads on personal and professional agents" [00:07, 00:13].  
* Kavya Kopparapu claims the model features "active memory," allowing it to retain user habits, preferences, and conversational history across "days, weeks, months, and beyond" [00:46].  
* Cosmo Du claims the team specifically trained the model on simulated real-world failures so it can anticipate and avoid failure modes [01:00].  
* Quentin Wellens claims "active focus" trains the model to persevere through blockers and try alternative solutions rather than giving up [01:17].  
* John Cherian states the model's data mixture makes it state-of-the-art for daily practical knowledge tasks such as health, finance, and legal document review (e.g., leases) [01:31].  
* Elaine Le claims the model can autonomously research real estate listings across multiple daily sources and contact landlords on the user's behalf [01:49].  
* Alexandr Wang claims Muse Wonder is available today through the Meta Model API and Muse Code, with rollouts in the consumer Muse app arriving first for subscribers [02:17].

**Notable quotes**  
* **[00:05]** "Today, we're releasing Muse Wonder, our largest and strongest model yet, and our next step towards personal superintelligence." — Alexandr Wang  
* **[01:12]** "Active focus gives our model a tremendous amount of perseverance." — Quentin Wellens  
* **[02:17]** "Muse Wonder is available today through the Meta Model API and Muse Code." — Alexandr Wang  

**Assessment**  
This is an official promotional product announcement video from Meta detailing the high-level design philosophies (active memory, active focus, agentic knowledge work) behind Muse Wonder. No live user interface captures, raw terminal sessions, or quantitative benchmark scoreboards are displayed; the demonstrations are shown exclusively via stylized 2D graphic animations and team testimonials.
