# Meta releases Muse Spark Open, a model anyone can download

Meta released Muse Spark Open, an open-weight AI model that developers can download from Hugging Face or use through services such as OpenRouter and Groq.

October 15, 2026 · Launch

Meta released Muse Spark Open, an open-weight AI model that developers can download from Hugging Face or use through services such as OpenRouter and Groq. Meta calls it the most capable US open-weight model yet and says it is strong at long, multi-step tasks and coding. It needs serious hardware, such as two top-end Mac Studios, and its licence limits some commercial use.

**Why it matters to you:** Open models let schools, businesses and governments run powerful AI on their own machines, so sensitive data never has to leave the building.
