October 16th, local time, October 15thMeta Open weights issued AI Models Muse Spark Open. Meta officially declared that:Muse Spark Open is the most powerful American open weight model to date.
Muse Spark Open supports the context window of 1M token by using a primary multimodular structure with a total parameter volume of 816B (with activated parameter 42B). The model was designed specifically for code construction in collaboration with intelligent bodies and demonstrated excellence in handling long-range missions, complex software engineering and multi-step reasoning。
Thanks to the latest MLX framework, Muse Spark Open became the first Mac Studio in the same level to run locally on the desktop with two apples, M5 Ultra chips (512 GB memory version)。
As of this date, developers will be able to call Muse Spark Open through API platforms such as Baseten, Fireworks AI, Groq, Modal, Nebius, OpenRouter and Together AI; model weights have also been synchronized with Amazon SageMaker AI, Google Cloud Model Garden, Hugging Face and Microsoft Foundation Models。
The model has been adapted to mainstream reasoning engines such as SSGLang, vLLM, TensorRT-LLLM, Hugging Face Transformers, Apple MLX, Allama.cpp and Unnsloth, and has been Depth Optimised for AMD, Apple, Intel and Inveida chips. The developers can also easily redevelop and customize on the basis of the PyTorch framework。
Muse Spark Open targeted security alignment during the post-training phase. The baseline test results indicate that the model has a high safety and security capability for all measured risk dimensions。
The weight of this model is based on the release of Muse Model License with a restrictive commercial clause, which is available free of charge to most developers。
