Meta is back. Muse Spark scored 52 points on the Artificial Analysis Intelligence Index, ranking 4th behind Gemini 3.1 Pro, GPT-5.4, and Claude Opus 4.6.
Muse Spark is the first new release model since Llama 4 in April 2025, and it's also Meta's first non-open weights model.
Muse Spark is a new model from Meta evaluated by Artificial Analysis. We received early access rights from Meta and conducted independent benchmarking.
This model is the first frontier-class model from Meta since the release of Llama 4 Maverick in April 2025, and it's particularly noteworthy as the first Meta AI model not to be released with open weights.
This release marks Meta's return to the frontier competition after a year of silence, following its reorganization of AI capabilities into Superintelligence Labs.
For reference, previous Llama 4 Maverick and Scout models scored 18 and 13 points respectively at the time of their release based on non-disclosure model standards. Muse Spark scores 52 points. In effect, it has almost completely closed the gap with the top models in just one release.
While this model is not open source and currently inaccessible through API, Meta has announced that it will be available soon. Additionally, Meta plans to integrate Muse Spark into its own products, including Meta AI chat services, Facebook, Instagram, and Threads.
