it’s ok sarah muse is thinking about you too

you can now add your muse to your instagram profile :) show off your superintelligent sidekick to all your friends!

1/ we just publicly released Muse Spark 1.3 max! we see significantly stronger coding and agentic performance on muse spark 1.3 max, so would strongly recommend trying it out even if you've already tried muse spark 1.3 high or muse spark 1.3 xhigh.

1/ today, with the launch of muse image and the preview of muse video, we wanted to share more samples from the model alongside research details and eval results see some more samples from muse video below (and see thread for research blog!)

1/ muse spark 1.2 is a very strong multimodal model—it can do visual coding, robotics planning, and audio-visual understanding that all come together through agentic tools.

4/ to achieve maximum memory efficiency, we quantize model weights to ~4-bit, getting the language model under 20GB with room for the kv cache, perception encoder, and drafter alongside it. a dflash drafter proposes blocks of tokens the main model verifies in parallel, so it stays responsive.

2/It's a step up on reasoning and coding. compared to Muse Spark 1.2, Muse Spark 1.3 wastes fewer turns, uses ~20% fewer tool calls, ~25% fewer tokens, and holds onto requirements well during long-horizon tasks.

1/ today we're rolling out Muse, our new personal ai assistant. Muse is always-on, wicked fast, can use a browser, connect to your apps, and is designed to be secure. try it now:

1/ muse for small businesses 📊 we found lots of people using muse to run their small business. plumbing businesses, grocery stores, farms, restaurants, and shops. today we're launching a bunch of connectors to make that easier!

muse is going NATIONWIDE to a television near you this is our first @muse ad ever, going live this weekend! we hope you like it while watching the big game(s)! big ups to Josh Ginsberg, denise, and the whole meta marketing team ❤️

Excited to share Vibes — a new feed in the Meta AI app for short-form, AI-generated videos.

how it feels to still have friends who aren’t on muse yet

MUSE RESEARCH ALERT: 1/ meet Muse Realtime Avatar, the state-of-the-art model that brings your muse to life alongside Muse Realtime Voice! it animates your muse as it talks to you. voice &amp; video are in sync, so muse will answer in under a second, for as long as you want to chat.

MUSE FEATURE ALERT: you can video chat with your @muse coming soon! it talks back in real time, and you get to prompt exactly how it sounds! (iphone screen record doesn’t record the sound so you’ll have to try it yourself with your own muse to hear the voice)

1/ we just publicly released Muse Spark 1.3 max! we see significantly stronger coding and agentic performance on muse spark 1.3 max, so would strongly recommend trying it out even if you've already tried muse spark 1.3 high or muse spark 1.3 xhigh.

1/ muse code is out of beta. launching with an sdk in developer preview to build your own agents on top of it and rolling out monthly subscription plans. copy-paste into your terminal: curl -fsSL | bash

1/ muse spark 1.2 is a very strong multimodal model—it can do visual coding, robotics planning, and audio-visual understanding that all come together through agentic tools.

1/ i’m really impressed by the careful work we did to make Muse secure. you can read our technical post here:

3/ computer use: it can operate desktop, browser, and mobile. muse spark 1.1 is trained to know when to automate and when to use interfaces directly. it scripts when that’s faster, clicks when direct interaction is simpler, and batches actions at each step.

2/It's a step up on reasoning and coding. compared to Muse Spark 1.2, Muse Spark 1.3 wastes fewer turns, uses ~20% fewer tool calls, ~25% fewer tokens, and holds onto requirements well during long-horizon tasks.

I testified at today's Energy and Commerce Committee hearing on AI. The CCP has an AI master plan that’s working. I told Congress that America must do the following to win on AI: Dominate, Unleash, Innovate, Promote. 🧵

3/ already powering dictation in the meta desktop app and muse code. live now via meta model api

Today, Scale AI is launching our 2 major platforms to bolster government and enterprise: 🎖 Scale Donovan, the AI copilot for defense 🏙 Scale EGP, full-stack generative AI for global enterprise 👇 See Donovan in action below 🧵 on our platforms and why they are so critical

MUSE RESEARCH ALERT: 1/ meet Muse Realtime Avatar, the state-of-the-art model that brings your muse to life alongside Muse Realtime Voice! it animates your muse as it talks to you. voice & video are in sync, so muse will answer in under a second, for as long as you want to chat.
