About
Muse Spark is the first model in Meta's Muse family, developed by Meta Superintelligence Labs (MSL). It is a natively multimodal reasoning model with capabilities including tool-use, visual chain-of-thought reasoning, and multi-agent orchestration. Muse Spark achieves 58% on Humanity's Last Exam and 38% on FrontierScience Research benchmarks, while being competitive with Llama 4 Maverick at over 10x less compute. Available via meta.ai and the Meta AI app; private API preview only — not open-source.
Muse Spark is a proprietary model in the Muse family. The structured metadata tracks multimodal input, reasoning, function calling, and tool use. Headline tracked benchmarks include MMMU Pro 80.4, Chatbot Arena 1491.0, and Google-Proof Q&A 89.5.
