What Muse Spark Open offers
Muse Spark Open is an independent website for developers working with Muse Spark Open. We provide model introductions, running and deployment information, developer resources and an operated API service. This site is not affiliated with or endorsed by Meta.
The model was released by Meta Superintelligence Labs. It has 816B total parameters, about 42B active per token and a 1M-token context window. Its native inputs include text, images, video and audio, with text output. Coding, tool use, agent workflows and long-horizon tasks are central use cases.
Model resources for real development tasks
AI developers can explore coding and integration tasks; agent builders can evaluate planning and tool use; inference teams can compare deployment frameworks; researchers can assess quality on their own datasets.
The developer guide links to official weights and covers SGLang, vLLM, TensorRT-LLM, Hugging Face Transformers, Apple MLX, llama.cpp and Unsloth. Model weights are subject to the Muse Model License and Usage Policy. Review the official model card for current requirements.
Playground, account tools and credits
The playground uses this site's configured model service and account credits. Its current text and image/video URL inputs do not expose every native model capability. Conversations remain on the current page; copy important replies before refreshing. The account assistant has separate history and tools.
