Muse Wonder Full vs Muse Wonder: which runs Meta Muse?

What are Muse Wonder and Muse Wonder Full?

Muse Wonder and Muse Wonder Full are two new AI models from Meta Superintelligence Labs. Meta released them on October 12, 2026, and built them to run agents that work for you over long stretches. They follow Muse Spark, the model that launched in April and has powered the Muse agent since September. Meta calls the pair its most capable models yet, and the benchmarks support at least part of that claim. On a widely watched independent intelligence index, Wonder Full scores 56 and Wonder scores 52, up from 48 for Muse Spark 1.3. On a benchmark that tests coding in the terminal, Meta reports a jump from 33 to 57 percent. That's a real leap, not a rounding error.

Two new features matter most for everyday use. Active Memory lets the model keep key details across conversations and bring them back when they're relevant. You shouldn't have to repeat that your accountant is called Ruth or that you never fly before 9am. Active Focus is stubbornness in a good way. If a dinner reservation fails or an online form throws an error, the agent tries another route instead of stopping to ask what to do. Meta's AI chief framed the release around exactly that problem: an agent that gives up on a booking halfway through. Both models also have a one-million-token context window, so they can read very long documents in one pass.

Step back and the picture gets clearer. Meta has spent the past year rebuilding its AI work, and this is its first true frontier model in over a year. It's also a revenue test. Meta wants to see whether people will pay for AI outside its ad business, which is why the best model sits behind a subscription. If you run a small business or a busy team, the benchmark scores are the least interesting part. Your questions are simpler. Does Muse get better at the admin you'd actually hand it? Can you use it where you already spend your day, which for many people is WhatsApp? And which version do you even get? The rest of this piece answers those, in that order.

Which Muse plan gets Muse Wonder and which gets Wonder Full?

Only Muse Code subscribers can use Muse Wonder Full. The standard Muse Wonder is available today on Meta's developer API and in Muse Code, and it's coming to the Muse app soon, starting with paid subscribers. That surprises a lot of people. You'd expect the best model to run the flagship consumer agent, but for now Meta is keeping it for its coding product. Wonder Full isn't for sale through the API at all, and Meta hasn't said when, or whether, it will reach the everyday Muse app. Meta's own messaging hasn't helped. The official announcement says Wonder will power Muse "soon", while the CEO's launch posts suggested you could subscribe and use it today. Expect some confusion for a few weeks.

For regular Muse users, the plans haven't changed. There's a free tier with a weekly usage limit, a Power plan at $20 a month and a Maximum plan at $100 a month. Wonder is coming to the paid tiers first, so free users will probably stay on Muse Spark for a while. Developers pay per use instead: $4 per million input tokens and $20 per million output tokens, roughly three times what Muse Spark costs per call. Most small business owners can ignore those token prices, since you're not building anything on the API. The monthly plan is the number that matters. Reports also say Muse subscriptions are still in limited testing and aren't offered everywhere, so even with a credit card in hand you may not be able to upgrade.

Our take: for a business owner, the split between Wonder and Wonder Full matters far less than the headlines suggest. The two models are four points apart on the intelligence index. The gap that decides whether you use an assistant on a Tuesday morning is a different one: it's whether the agent can do the job where you actually work. A smarter model in an app you forget to open won't send your Thursday timesheet reminder. Choose an assistant for where it lives and what it reliably does. Then worry about which model is under the hood. Benchmarks are a fine tiebreaker, but they're a bad reason to change how you run your week.

What gets better in Muse with Wonder, and what doesn't?

The new models should make Muse noticeably better at finishing multi-step tasks and remembering context. They don't change what Muse is allowed to do, where it works or how you reach it. Better reasoning should mean fewer half-finished jobs. A form that errors out gets a second attempt, and a failed booking gets an alternative. Active Memory should stop the agent asking you the same questions twice. Muse's core actions already include booking travel, filling in forms, shopping and summarizing documents, and once Wonder reaches your plan you should hit fewer dead ends on all of them. Developers using Muse Code will feel the jump in coding scores most, because that's where Meta put its best model first.

What stays the same matters just as much. A new model doesn't add countries, so Muse is still officially limited to adults in the US and Canada. It doesn't add channels either. Muse still lives in its own app, on the web, on Mac and as a chat inside WhatsApp. Nothing in the launch mentions WhatsApp groups, shared lists, or the agent messaging other people for you. Free users won't feel any of it until Wonder reaches their tier, if it ever does. Maybe your complaint about Muse was that it's not available where you live, or that you have to remember to open it. Wonder fixes neither problem.

There's a quieter trade-off too. A more persistent memory and a more persistent agent are great when they work and a little unnerving when they don't. An agent that keeps trying new approaches without checking in is exactly what you want for a restaurant booking. It's exactly what you don't want for anything that spends money or speaks for you. Before you hand any agent real admin, ask two questions. What does it do when it's unsure? And do you see what it's about to send before it goes out? For a small business, those answers count for more than a few benchmark points. One wrong message to a client costs more than ten minutes saved.

Does Meta Muse work in WhatsApp for reminders and group admin?

Yes, Muse works as a chat inside WhatsApp, but only in the US and Canada, and the Wonder launch doesn't change that. Meta switched Muse on in the US on September 8, 2026, and in Canada ten days later. The same country limits apply everywhere you can reach Muse, including the WhatsApp chat. WhatsApp ties your account to a phone number with a country code, so a VPN is unlikely to help if your number starts with +44, +972 or +55. Don't confuse Muse with Meta AI, the older chat assistant built into WhatsApp in many more countries. Meta AI answers questions. Muse is the agent that's meant to do things for you.

Inside those two countries, Muse can schedule reminders, and guides show recurring ones like a Friday-afternoon nudge to check next week's schedule. That's handy for personal admin. Group coordination is where things get thin. The Muse launch and the Wonder launch both focus on one-to-one tasks: booking, shopping, forms, documents and code. Neither describes Muse sitting in a WhatsApp group to recap a busy thread, run a poll, split an expense or nudge everyone on a schedule. Maybe that's coming. For now, if your real headache is a team chat where nobody sends their timesheet, Wonder does nothing about it. If you want the wider picture, we've put together a roundup of AI agents you can text on WhatsApp.

Most WhatsApp users live outside North America, so for most of them Muse isn't an option today, with or without Wonder. That matters because WhatsApp-first places like Israel, most of Europe and Latin America are exactly where people run businesses, households and five-a-side teams through the app. As of early October, Meta hadn't announced a third launch country, and the UK, the EU, India and Australia had no dates. Plenty of assistants are going after this gap. Our look at whether Google's Gemini agent works in WhatsApp covers one of them. If you're reading this in Tel Aviv, Madrid or São Paulo, here's a WhatsApp assistant that works where Muse doesn't.

What can you use today for reminders and team admin in WhatsApp?

If you want an assistant that already works in a normal WhatsApp chat in any country, Agent Sonic handles the admin side today: reminders, to-dos, notes, group reminders, documents and follow-ups. You message it like any contact. There's nothing to install and no dashboard to check. Type or send a voice note: “Remind me to call the accountant every Monday at 9.” “Note that the Levy order ships on the 14th.” “What did I say about the van insurance?” Sonic keeps a persistent memory, so that last one actually gets an answer. It reads what you forward it too, whether that's a contract PDF (“What are the cancellation terms?”), a spreadsheet or an invoice. And it can search the web when you need a quick fact.

Group admin is where Sonic goes beyond what Muse offers right now. Add Sonic to a WhatsApp group and it can post automatic reminders on a schedule, recap a thread you missed, run a poll, keep a shared list and split expenses. A team lead might send, “Remind the team every Thursday at 4 to send timesheets.” A flatshare might send, “Remind everyone on the 1st that rent is due.” A coach might ask, “What did I miss in here since Monday?” Nobody in the group has to download anything, and that download step is usually where tools like this die. You can also have Sonic create Google Calendar events and update Sheets or Docs straight from the chat, so a meeting gets booked instead of just discussed.

Then there's the job most people dread: asking someone for an answer and waiting for it. On the Pro plan, Sonic's outreach tasks message people for you. The feature is in Beta and may be paused from time to time. You might send, “Ask Dana when the invoice will be ready and let me know.” You see the exact first message before anything goes out, and you approve it with “yes”. Sonic then writes from its own number and introduces itself as your assistant. It never pretends to be you. The limits are deliberate: one task at a time, up to three people a day, and one-to-one chats only. Our step-by-step guide to having Sonic message people for you walks through it. When you're ready, get access to Sonic and you'll receive its number and onboarding.
