Muse Spark Open is Meta's answer to Qwen, GLM, and Kimi in the open-weight race.

Meta released Muse Spark Open, an open-weight model with 816 billion parameters that handles text, images, video, and audio with up to one million tokens of context. It performs roughly on par with the most capable open-weight Chinese AI models on benchmarks.

Why it matters: It adds a major Western open-weight model to a field largely led by Chinese systems such as Qwen, GLM, and Kimi.
