Meta Releases Muse Spark Open, an 816B-Parameter Open-Weight Multimodal MoE Model
Meta has officially released Muse Spark Open, an 816-billion parameter open-weight multimodal Mixture-of-Experts (MoE) model. The company claims it is the most capable US open-weight model to date, a claim primarily asserted by Meta itself and echoed in community forums. This release marks a significant development in the open-source AI landscape, with Meta positioning the model for various advanced applications. The model is notably optimized for Apple's Mac Studio, though it requires a substantial 1TB of RAM to operate, making it accessible primarily to high-end users. It is also available on vendor platforms like Together AI and Amazon SageMaker JumpStart, and is highlighted for its potential in agentic coding workflows with NVIDIA hardware. Some outlets frame the release as a collaboration between Apple and Meta, while others note its competitive stance against models like Qwen and GLM, with one community post even suggesting smaller models outperform it.
