Meta Open-Sources Muse Spark: 816B-Parameter Multimodal Model with 42B Active

qinzytech · x · 2026-10-16

Meta has released Muse Spark Open (816B-A42B) as open weights on Hugging Face: a MoE multimodal model (Image-Text-to-Text) with 816B total and 42B active parameters, available in both BF16 and NVFP4 precision. Meta says it covers visual coding, audio-video understanding, robotics, and real-world agentic workflows, framing it as multimodal reasoning grounded in action. The family also includes Muse Glimmer 30B, a smaller multimodal agentic model for local deployment with BF16 weights, GGUF k-quants, and ExecuTorch builds, already with hundreds of thousands of downloads.
