I few notes on Meta's new Muse Glimmer 30B - their first Apache 2.0 licensed open weight model (the Llama models had a janky non-OSI license) simonwillison.net/2026/Aug/10/in…

Big fan of @Muse Took grok bot & ran with it, haven't tried any serious work with it yet but it's working on getting me a refund from enterprise car rentals, booked me a flight for a Christmas trip & found me some pretty sick deals on recliners all within less than an hour of

Meta employee here! I built a finance calculator for Singaporeans to help with adulting decisions, like mortgages, retirement, savings, and a bunch more! Entirely with Muse! gethowmuch.net

Had it check for a slot for a swimming class for both my kids. Took 2 days, but found one and booked it for me without me having to continue refreshing

Just booked flights on @Muse. Amazing experience. Infinitely better than @Expedia who I have been using consistently for years.

Having @Muse find the best offer to sell my Model X. Then it’s finding a lightly used new version of the same car

.@Muse just saved me $603 a year on my car insurance after analyzing my policy. This assistant is really good at getting things done.

Mine took a cancelled Alaska flight + two Lyft receipts from my email and filed the whole claim: converted email to PDF, fought a broken upload widget (said 2.5MB, real limit 512KB), submitted $189.37 + goodwill. Came back with case number. I just watched. Very smooth, I asked

Got muse cli hooked up for both default agent action and lazy-loading. Come give it a try, @finkd 🙏 github.com/omacom/omarchy…

I asked Muse to renew my US passport online. It did 95% of the work and when I needed to chime in (enter ssn/ upload picture) the browser handoff was smooth. Also it booked our flight tickets for my wife and I e2e on Amex travel. First time an agent is able to complete such task

Infinite Improbability

@v01dp1r4t3

Today @Muse shopped for a new garage freezer, got the best price for my required specs matching it's replacement, ordered it, kept track of the delivery, then filled out and submitted the registration. I watched every step of the way redundantly, had to enable a few more things

Oh that's just 1 example! Muse now runs my Shopify stores, emails and coordinates with my employees, runs and manages my Asana....the list goes on! Love @Muse ❤️

It did make me a purchase lol. Ram for my computer for New Egg. It setup link and bought it and the cool thing was it helped me figure out I had two extra ram slots I forgot about.

Very nice and tight @WhatsApp integration here, not only can you chat with Muse from whatsapp, you can view those in read only mode as one of the chats!

Day 2 of building products for agents. I present to you musetv.live - think your @Muse agent & Tamagotchi had a baby.

Negligible Capital

@negligible_cap

Sure $META Muse is good. Really good even. I had it go through my entire email last night and unsubscribe me from dozens of promotions and it only used around 10% of the free token budget But Instinct is also really good and didn’t need to pay Alex Wang a billion dollars to get

Super fun fact I just found about @Muse!! If you connect your Robinhood banking account , it’ll be able to see your investment portfolio and provide insights and create finance goals and plans Sorta a loophole for a Robinhood connector, super cool!! @alexandr_wang @MattPRD

@xf1280

Muse Spark is agentic, which means you can ask it to leverage different test-compute scaling methods to improve quality. Here I ask the model to use parallel subagents to do counting and the results are greatly improved! meta.ai/share/aD4KAPeV…

I’m using Meta Muse to book a three day trip and it’s a breeze! A little slow doing the tasks sometimes but hey it’s better then me doing the tasks

@OffZeroCyber

Here is how I started the conversation with my @muse: I want to experiment with turning you into a personal email security agent for my Gmail. The goal is to see how far you can go toward acting like a lightweight ICES/email security platform for an individual user. Start by

Introducing floo, a cloud platform where your personal agent can build and run apps for you. Tell Muse what you need. It builds the software. floo handles hosting, data, and login, giving your Muse tools it can keep using and you an app to see and guide its work. Launching

Pelicans for Meta's new Muse Spark models - plus I did a bit of a deep dive into the Code Interpreter and fascinating "container.visual_grounding" tools in their meta.ai chat UI simonwillison.net/2026/Apr/8/mus…

@JohnnyLoincloth

Had an issue with a flight last week while at a conf w/ zero time to deal with customer support. Told Muse my problem and sent it in there. Other than providing it a verification code, was completely seamless. Problem solved in 15 mins while I was in meetings

Very cool experience with Meta Muse. My wife and I were chatting about college tours on the way to get food. I whipped out Muse, listed the schools. Muse did the obvious thing and found the windows for booking etc but, surprisingly, it generated a PDF! Super cool and it was

Artificial Analysis

@ArtificialAnlys

At 30B parameters, Muse Glimmer sits near the Intelligence vs Parameters frontier for open weights models: 5 points above Gemma 4 31B (Reasoning) at the same size, effectively matching Kimi K2.5 (Reasoning) at 33x fewer total parameters, and just behind Qwen3.6 27B (Reasoning),

@sunilsrathode

asked muse to lookup all county courts in California for any traffic citation on my name, It actually found a recent case, set up payment through Stripe Link, done in minutes. Fast, seemless and super easy to use. Offloading all such tasks. Thanks @alexandr_wang and the team.

Muse has been checking the Apple Store online for me and notified me when an iPhone became available to pre order! Saved me a lot of time and effort! Amazing!

Muse bought tickets at Ticketmaster successfully, where Instinct failed

@AaronSkrivan

Finally put @Muse to the test. Pretty shocked. I had it find unclaimed property and file all the paperwork. Free $97. Then I had it opt me out to all major data brokers. Finally, I had it add all my Amex offers. Saved 200 manual clicks. @alexandr_wang 🫡
