Muse Spark 1.2
Muse Spark 1.2 is a proprietary Meta multimodal reasoning model for coding and agentic knowledge work. The 1.2 update focuses on coding and tool-driven visual work, launching alongside the Muse Code terminal agent with stronger long-task and multimodal capabilities. It accepts text, images, video, and audio and produces text; the API specifies a 1,048,576-token context for these versions. Standard and, where offered, Contributor access use the same model capabilities but different data-use terms. Contributor access is a serving tier rather than a separate model. Future open-weight plans are not a weight release.
