What it does
Muse Spark Open is a Meta model that reads text, images, video and audio and replies in text. It is built for coding and agent work, where the model plans several steps, calls outside tools and tries again when a tool call fails.
How to use it
Input → action → output: send a screenshot, chart, document or coding task with your question, and read the text reply. Use a third-party inference provider's API, or download the weights from Hugging Face and run them with a framework such as SGLang, vLLM or Llama.cpp. Meta recommends high or xhigh reasoning effort for complex tasks.
Common use cases
- Send a screenshot, chart or document and get a written explanation of it.
- Give it a software bug and have it write and debug code to resolve it.
- Give it another model's answers and have it evaluate them.
Can I use this?
Requirements First, request access on the Hugging Face page, since access is manually gated, and accept the Muse Model License. To run it yourself you need a GPU with at least 700GB of VRAM for NVFP4 or 2TB for BF16, plus an inference framework. The source does not name API providers or account steps.
Caveat Meta recommends deploying it inside a broader AI system with extra guardrails. The output is text only, and the license terms are not summarized here.
Worth knowing Meta recommends deploying it as part of a broader AI system with extra guardrails. It replies in text only, and the license terms are not summarized here. Requires accepting the license on Hugging Face (free to request; the publisher approves each request).
