EDIT: An open weight version of Muse Spark 1.2 is going to be released as well:

Considering that Meta distills Qwen[1] (and should!), it'd be hilarious if Muse loses the head-to-head; the "distillation attack!!1!" people claimed distillation on release n-1 is enough to match the intelligence of the latest version.
1. They wrote a paper about it
Surprising that Meta don't host this model, even as rate-limited free-tier.
> open weight version of Muse Spark 1.2
Wait. Is this "version" different from what Meta serves?
Huh, well... no? Gemma A4B and Qwen A3B are quite popular in fact. I'm sure 3.8 35B A3B will outperform 3.6 27B by all metrics
"... Soon we'll also release the weights for Muse Spark 1.2, our latest foundation model..."
This is bigger news - good for self hosting enthusiasts and a strategically sound move for Meta. Any push towards 'anti Chinese' models will directly benefit Meta as the competition on the frontier open-weights American models is almost non-existent. Meta will have no problem being #1.
The quantized releases often change in the weeks following release as new improvements are discovered, so either use a tool that checks HuggingFace for new versions or manually check back in a few days or weeks to check for improved versions.
Initial reports are good. It hasn't been out long enough for anyone to really test thoroughly, but the people I know who have stable non-public test cases are reporting impressive results compared to even Qwen3.6 27B. That's a good sign that this might not be benchmaxxed (trained to excel at public benchmarks with less impressive performance on general tasks) which has been becoming common with recent releases.
www.reddit.com/r/localllama is a good place to keep up with the details from people who are actually using it. It feels strange to recommend a subreddit over Hacker News, but on this topic the /r/localllama threads are much more on topic right now if you're looking for information about the model.
There are some initial reports that even the 2-bit quantization is looking somewhat usable. That might make it small enough to squeeze into 16GB GPUs. I'd take those reports with a grain of salt because early tests are often optimistic and I've yet to see good results from anything 3-bit or less, but it should be fun to experiment with.
Starting this morning I am running their new local 30B model muse-glimmer on my old MacMini 32G using Ollama (remember to increase the context size!) and pi coding harness. I am getting good results with muse-glimmer running locally, with the caveat that everything runs slowly (e.g., give it a task and then go walk outside or do Qi Gong exercises for a while).
1. The template name is Onyx ATEM as found in the tool call exception message
2. It appears to be following a harmony-style chat template. But the tool use seems to be a xml like :<atem:function_calls> / <atem:invoke> / <atem:parameter>
3. atem: a internal joke of meta in reverse?

Unfortunately I don’t have enough experience with Qwen 27B to immediately compare, but I do it’s Qwen 3.6 35B A3. It’s much slower obviously but it seems to be way more efficient with its thinking to the point that using it might actually be faster. I find Qwen and some others rehash the same things over and over when thinking without getting anywhere, in mg limited checks here Muse is much better.
The progress compared to Qwen3.6 27B is good, not that impressive, it's a 4 months old model. (kuto to them to compare to 27B dense and not 35B MoE, it's more fair to do so). It is very probable that Qwen3.8 27B will crush Glimmer-30B on most benchmarks.
The next iteration in LLM products is a 24/7 thinking loop where the claude-code like thing gets input continuously from your wearable, notifications, and newsfeeds and is constantly preparing things for you.
It has all of the components of a pelican riding a bicycle, though not exactly arranged in the right order!
(For comparison, here are the pelicans I got from Muse Spark 1, 1.1, and 1.2: https://bsky.app/profile/simonwillison.net/post/3mseqv5z4qk2... )
The researchers releasing this stuff have almost nothing to do with Meta other than being bankrolled by the slaughterhouse.
You aren't the customer, you are the pawn in big tech's game of thrones. Your good will is a commodity to be traded, almost literally. It will be used against you the moment it's convenient. This is open weights because Meta couldn't monetize it in any other way than to cloud developer's judgement of their reputation.
But I guess most people just don't care.
I'm glad it's open. It does not make me think any better of Meta.
Fair on size, but the headline numbers are against a model a generation back
That's a modern gaming laptop; cheapest I see in the US with 24GB is $3.5k.
Should be quite a bit faster than the new M5 MacBook Pro, and you can run Linux on it!
For the same cost, you could run on a frontier model on a pro plan for two years. The economics dont make a lot of sense for this to me, so I would love some input on why people want to do this instead (privacy, for fun, etc).
Waiting on Q3 to download to check speed + do my usual anecdotes. I generate beefy code snippets and poems, and also ingest my HOA declaration and answer nuanced questions.
edit: i should've prefaced this somewhere with: This card ballparks at 800GB/s IO, which I can't seem to find easily on the market anymore. Kinda the ideal card for this model, if I just had a _little_ more VRAM (XTX is 24GB).
edit2: not mtp, this is dflash model (param in child comment). I'm up to ~60 tok/s generation and sitting at 19GB VRAM (i added --no-mmproj (makes it text-only i believe) because I'm used to speculative decoding wanting more VRAM and I'm already close to the limit :sweat_smile:)
It can do that, but its actual selling point appears to be a different take on guardrails and safety alignment.
Either that or the only new training data left was industrial quantities of dark romance literature and Wattpad.
Clever business move. 131k context is more than enough for that use case, and due to that small K/V footprint, you can probably have a bunch of characters on the same GPU.
Or it's just a happy little accident. We will never know.

I was informed that normal people use LLMs for mundane tasks like asking for a pancake recipie.
That it apparently can also do decently.
Unfortunately, it is also very confident, regardless of whether it is actually correct.
So maybe it should actually stay the smut engine and nothing else.
I like this class of model. Multi-token prediction makes it viable to run dense models at not-too-far-off speeds as MoE models with much better intelligence.
The submission’s title (open weights 30B local coding model) is luckily wrong: This is meant to be a general agentic model.
It even comes pre-quantized and with a MTP/drafter model. Looking good!
Let’s hope they aren’t dishonest with the benchmarks this time …
Anybody here succeed to run this on AMD?
Sure, you can get better performance from cloud models.
But most software, not just AI, will be faster and more reliable in the cloud. The question is do we need that additional power and cost.
If the answer is no, then just like other software, people will run AI locally.
I'll be interested to see how it performs with a LORA driven adaptor model stitched on to drive agentic security remediation tasks.
