Meta's massive multimodal coding agent 🦾 Meta released Muse Spark Open, an 816B-parameter multimodal MoE model for agentic coding, calling it the most capable US open-weight model. Image: Hugging Face Blog
Artificial analysis shows this: underperforming Qwen3.8 Flash Next and GLM 5.3 Flash, both of which you can run on a single B300 . I think Meta has a bit of catching up to do in the open-weight space. As an aside, it's really unfortunate t…
Like I said last week. I think zucks original llama thesis is proving more correct by the week. The rent market on intelligence never materialized, if you have THE frontier model, you can charge rent (for a few weeks, maybe month). But aft…
Since there are many comments here arguing that this is not open weight, I looked at the license. Basically, you're free to use this except this clause: > If the Licensee or any of its affiliates provide a third party with access to artifi…
They've done considerable effort in making sure this model can run on basically every model runner, from Unsloth to MLX, https://dev.meta.ai/docs/muse-spark-open/deploy
re: "Apple’s unified memory architecture lets the M5 Ultra's integrated GPU use up to 512 GB per Mac Studio, so two machines can hold an entire model. And the chip’s 1.2 TB/s of memory bandwidth is fast enough to read the small slice each …
I find it interesting how companies doing open weight models are shifting from advertising them as "the best" to "the best in the US/EU". One week ago Mistral advertised their model as "significantly outperforming any open-weight model dev…
I think a lot of people in this thread are openly dismissive: "oh its just open claw, anyone can and many have build that". I think what they are missing is the fact that there are not that many teams in the world that can deploy muse like…
39 on AA[1], about the same as Deepseek v4.1 flash and Mimo 2.5 Flash. Behind Glm 5.3 flash and Qwen3.8-Flash-Next [2] [1] https://artificialanalysis.ai/models/muse-spark-open [2] https://artificialanalysis.ai/models/open-source?models=mim…
Zuck said by himself that they will release the weights of Muse Spark 1.2, and now we only get that one. At least they bench similarly bad for the size on Artificial Analysis
I have just tried to download the models, but it is not that simple, because they are "gated models". This means that you must first create a personal account at Huggingface.co, then you must fill a request form for Meta, including whom yo…
Pretty sweet. I wonder if they can continue to distill this down so it runs smaller. I think we're at a point where more intelligence isn't really needed for a lot of use cases.
