Bonde](https://daily.dev/sources/5cqvizkr5tdfdotvdjulg)** · [@byteoutlaw](https://daily.dev/byteoutlaw) · 0 upvotes · 0 comments ## Summary Meta released Muse Spark Open, described as the most capable U.S. open-weight model to date, built with Apple to run on Mac Studio hardware. The model has 816 billion total parameters with 42 billion active parameters and a 1 million-token context window, targeting coding and agentic workflows. It can run across two 512GB Apple M5 Ultra Mac Studios using the MLX framework, leveraging unified memory and 1.2 TB/s bandwidth to act like a single machine with a terabyte of memory. The 512GB Mac Studio hasn't shipped yet but is expected later in the month, with the existing 256GB model already priced above $10,000. The model is available via API platforms including Baseten, Fireworks AI, Groq, Modal, Nebius, OpenRouter, and Together AI, and downloadable from Amazon SageMaker AI, Google Cloud Model Garden, Hugging Face, and Microsoft Foundry Models under a free license with limited commercial use allowed. ## Full article daily.dev links to this article rather than hosting it.
