Meta's product-oriented teacher model introduced April 8; Glimmer is distilled from its outputs.
No evidence-backed relationships are recorded.
Approval is what Meta describes guarding the way out of its new agent. The way in is a one-time connector grant across nine accounts, and the two published accounts of the closed test disagree on where you can get it at all.

Sensor Tower estimates Meta's Muse agent hit 5 million US downloads in 22 days with up to half of Meta's daily house-ad impressions behind it. For builders, the launch shows how far Meta's own apps can carry an agent before anyone knows whether users keep it.

Meta's six Muse Spark math papers, out October 2, label which passages the model drafted and which the researchers wrote. They show a chat assistant writing search code and proof drafts for mathematicians who chose the problems.
Reality
Meta's Muse has a free tier and OpenAI's Dots starts at $100 a month, though both agents keep working on their own cloud computer after the user leaves. For whoever rolls one out, the choice turns on who approves the agent's actions and where the work already happens.
Reality
Meta grouped Muse API, Muse Code and Business Agent into a new enterprise platform whose Muse Spark model costs developers $1.25 per million input tokens. The endpoint is ready to test today, while the enterprise package still has no published price or delivery date.

The 16MB download matters less than what it plugs into: Instagram and Facebook accounts, ad campaigns and Google Workspace, with Meta's training and ad-targeting policy attached.

Alexandr Wang says the new model costs developers no more than 1.2 and finishes the same work on about a quarter fewer tokens. That is a real saving on high-volume code generation and a rounding error most other places.

Meta's fourth Muse Spark in five months gains four points on Artificial Analysis' Intelligence Index, almost entirely in agentic tests, while two scores fall and the tier Meta benchmarked against rivals is still a limited preview.

Muse can open a browser and click buy, but the credential at checkout is Link built by Stripe, and the only money Meta has put a price on is a $20 and $100 monthly subscription rather than a cut of what the agent spends.

He refused a reported $1.5 billion package in August 2025, joined two months later for less, and held his exit until Muse shipped. Meta has promised a confidential version of that product before the end of 2026.
Reality
The Verge's hands-on found Muse cleaning an inbox and buying tank tops as advertised, but the consent screen only covers the accounts a user points it at, and the assistant volunteered data from ones nobody asked about.

The agent launched in the US on Tuesday with subscriptions at $20 and $100 a month, and employees testing it during launch week were still logging guardrail bypasses, logouts the system forced on its own, and monitoring that occasionally shut off without explanation.

Meta's Muse passed ChatGPT on Apple's US free chart with roughly 730,000 installs in its first five days. The stock has added more than a fifth of its value since details of the agent emerged.

At Connect, Mark Zuckerberg and Alexandr Wang gave Meta's three-week-old agent its own email address, a face for video calls and control of desktop apps. The open question for anyone trying it is what it can reach.
Reality
Alexandr Wang's hashtag challenge produced dollar figures from Meta staff and outside founders, none of them with independent before-and-after numbers, and the top Muse plan costs $1,200 a year before any of it counts.
Reality
Meta's Muse agent reached the top of Apple's free app chart by doing users' shopping for them, and Amazon shut it out of its store on contract grounds, a theory Amazon already lost a ruling on against Perplexity.
Reality
Meta says a setup error by Irregular, the outside firm running its evaluations, let its Muse Spark model reach the internet and exploit a live third-party service. Five organisations have now been breached this way.
Reality
The standard Muse Spark tier promises Meta will not train on your prompts and completions. The contributor tier hands that promise back and charges roughly a twelfth as much for input tokens, with a request cap to match.
Reality
Zuckerberg's 6,500-word essay promised everyone a personal agent. The pushback was about Meta's record, not the model, which is a messaging constraint for anyone shipping agents.

Meta's Muse can search, fill a cart and settle through Stripe's Link once a person approves the total, and the survey Fortune cites leaves at most 28 percent of shoppers willing to store the card it needs.
