we’re proud to be partnering with @1Password so Muse will be able to work with the logins you already have. more details on how we built all of this here: https://t.co/aKxcJYbfcH

Basil🧡@LinkofSunshine · 21 Sept

Just used Muse to call spectrum and negotiate my bill from $75 to $40 automatically. This feels like defecting but wowee

Chris Abraham 🐝@chrsabraham · 21 Sept

I just built the largest collection of helpful prompts (500+) to turn Muse into the best chief of staff, best marketer, best PM you've ever had. @Muse can be so much more than a glorified admin assistant. There are hundreds of ways to use it at your job. Completely free, check

Cline@cline · 6 Aug

We tried using Meta's new Muse Code agent, but it has a bug that doesn't let it sign in from a docker container. So we did a fun experiment: Meta claims Muse Spark 1.2 was co-trained with their Muse agent harness. So we extracted instructions from their system prompt and added https://t.co/zhxsezv6gs

Peter Yang@petergyang · 18 Sept

Meta's @Muse is the best personal agent I've tried to date. It actually save me $800+ a year on my cable and phone bills, which is just insane value for a free AI agent. Here's my new video where I walk through 10 of my favorite Muse use cases, including a personalized morning news feed, a habit tracker, and how I got Muse to call customer support and negotiate my bills for me.

BREAKING: Muse Spark 1.3 (xhigh) takes 1st overall on Website Arena with an Elo of 1362! This is a jump of 5 positions from Muse Spark 1.2, establishing a new Pareto frontier for Speed and Price. Only a month after the release of Muse Spark 1.2, @AIatMeta has topped this https://t.co/FObUHjHTsj

Meta for Developers@MetaforDevs · 2 Sept

Muse Spark 1.3 is now available in Muse Code and Meta Model API. It’s tuned for the agentic builds developers actually ship, including long-running, multi-agent workflows. 🧵👇(1/4) https://t.co/aS8cuVgMuU

Lucas Switzer@lucas_switzer · 12 Sept

A cool thing about @Muse is that every Muse runs on its own Linux machine. So you and your Muse can do normal Linux stuff together — like build your own terminal! https://t.co/aDy4pLVyrs

Cline@cline · 9 Sept

Meta’s Muse Spark 1.3 Contributor model is now available for free in Cline. Benchmarks show it’s similar in performance to Opus 5, but considerably more affordable. https://t.co/AZisU1VHls

Meta for Developers@MetaforDevs · 4 Sept

Muse Spark 1.3 with max reasoning is now available on Muse Code and Meta Model API. Developers can build with frontier performance without the frontier prices. We thought showing would be better than telling, and encouraged our friends in Meta Superintelligence Labs to come up https://t.co/2u6dMjWFEl

Artificial Analysis@ArtificialAnlys · 10 Aug

Meta returns to open weights: Muse Glimmer, its first open-weights release since Llama 4, scores 35 on the Artificial Analysis Intelligence Index. It is a 30B-parameter model, and the first from Meta to be released under Apache 2.0 Muse Glimmer (high) arrives 16 months after https://t.co/W7rzNI15PX

Vals AI@ValsAI · 6 Aug

Muse Spark 1.2 just cracked the top 5 on the Vals Index, at just $0.69 per test. This is 3x cheaper than Kimi and 10x or more cheaper than Fable, Opus, and 5.6 Sol. https://t.co/E2pFFqQiBI

Tom Collins@thetomcollins · 9 Sept

$META just went from 3.5% to 45.4% token share on OpenCode in just over two weeks Muse Spark 1.3 being good + free is enough to become the default for most users Default gets you usage → usage gets you data → data makes the next model better Anthropic and OpenAI can’t afford https://t.co/Vktxt3pgXI

Artificial Analysis@ArtificialAnlys · 9 Sept

Last week the Intelligence Index vs Cost Pareto frontier moved out substantially. Claude Fable 5.1, Muse Spark 1.3, and GPT-6 Astra each set a new point in efficient intelligence Link to analysis: https://t.co/CoUVoX9XNT https://t.co/lu5PvRLt89

Artificial Analysis@ArtificialAnlys · 10 Jul

Meta's Muse Spark 1.1 scores 51 on the Artificial Analysis Intelligence Index and is cost and token efficient compared to its peers Muse Spark 1.1 (xhigh) improves 8 points over Muse Spark 1.0 (43) in three months. It is effectively tied with GLM-5.2 (max), GPT-5.4 (xhigh), and https://t.co/f2NmTlrTDZ

Paweł Huryn@PawelHuryn · 13 Sept

So, I finally tested Muse Spark 1.3. 2 real repos, 105 planted bugs, find and fix what you can. Original harness and API. Big surprise: Muse Spark 1.3 (max): 33 Fable 5.1 (high): 33 Grok 4.6 (xhigh): 27 Opus 5 (max): 27 Muse Spark 1.3 (high): 19 Meta joined the frontier. https://t.co/eADWZly21Q

AI at Meta@AIatMeta · 20 Aug

Today we’re also previewing WildArtifactBench, an internal evaluation framework designed to assess agents on complex, real-world tasks across diverse deliverable formats. By using win rates and Elo scores from human and agentic preference judges rather than strict ground-truth https://t.co/eXWkTrOmPo

Unsloth AI@UnslothAI · 13 Aug

You can now fine-tune Meta Muse Glimmer 30B for free! 🔥 Our free notebook also supports GRPO RL training. Unsloth trains Muse Glimmer 1.5× faster with 50% less VRAM vs FA2 setups.

Muse Image is now available on Meta Model API and priced for production volumes at $0.01/image. It’s an agentic image model that reasons before it renders. Each call searches the web to refine the output through iterative passes and evaluates the prompt for precise elements https://t.co/xzH4ymjejl

Alexandr Wang@alexandr_wang · 12 Apr

i find muse spark is very good at data analysis—both finding relevant open-source data and analyzing it. for example, here's my results for analyzing global share of GDP over past century: https://t.co/pD4q7n7mqX https://t.co/xHcZTIgAl4

Matt Van Horn@mvanhorn · 23 Sept

Funny @Muse transcript trying to book a karaoke reservation via phone call. The person on the other end asked if it was AI, Muse said it was an assistant calling on Matt's behalf, and the recipient refused to talk to an AI.

OpenRouter@OpenRouter · 21 Aug

We’re excited to bring @AIatMeta’s Muse Spark 1.2 contributor tier to OpenRouter. At $0.10/M input and $0.20/M output, It’s meaningfully cheaper than Muse Spark 1.2 and beats other comparable models on real cost, providing frontier intelligence-per-dollar. https://t.co/YNf6EprqiW
