Muse Spark Open

Muse Spark Open (meta/muse-spark-open) is Meta's 816B-total / 42B-active open-weight sparse Mixture-of-Experts reasoning model, purpose-built for long-horizon agentic coding. With a 1,048,576-token context window, native multimodal input (text/image/video/audio), and GQA attention across 62 layers, it trades raw code-writing dominance for best-in-class tool orchestration and codebase comprehension at a ~110 tokens/sec serving rate.
