Social post reporting Meta's release of Muse Spark Open, described as the most capable US open-weight model: 816B total and 42B active parameters, a 1M-token context, and text, image, video and audio input in one model. It is pitched at coding and agentic work and tuned to run on two M5 Ultra Mac Studios, with weights available at release. The poster notes that in Meta's own chart, China's Kimi K3 and GLM 5.3 still beat it on coding.
TL;DR Meta releases Muse Spark Open, an 816B/42B-active open-weight multimodal model with 1M context that still trails Kimi K3 and GLM 5.3 on coding.
