Muse Spark Open
Meta has released Muse Spark Open, an open-weight AI model with 816 billion total parameters optimized for coding and complex reasoning tasks, now available for developers through multiple platforms including Hugging Face, Amazon SageMaker, and Google Cloud. The model can run on consumer hardware for the first time, specifically on two Apple M5 Ultra Mac Studios connected via MLX framework, allowing users to operate advanced AI capabilities on their own desktops. Muse Spark Open is accessible through API platforms like Together AI, Fireworks AI, and Groq, as well as through various inference engines including vLLM and TensorRT-LLM with optimizations for AMD, Apple, Intel, and NVIDIA processors. The model includes additional safety post-training measures and is released under Meta's Muse Model License with limited commercial terms that allow many developers to use it for free.
Why it matters The release of the most capable US open-weight model to date resets the competitive landscape for who controls frontier AI.
