About
Muse Spark is the first model in Meta's Muse family, developed by Meta Superintelligence Labs (MSL).

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.
