Superseded by later 1.x versions, so most people will meet it only as the free model inside Meta AI.
Kenning's take
What it does
Muse Spark is the first model in Meta's Muse family, built by Meta Superintelligence Labs to combine image understanding with reasoning and agent abilities. Meta says it reaches the capability of Llama 4 Maverick with much less training compute, and it has a Contemplating mode that runs several agents in parallel. It launched in the Meta AI app and on meta.ai, with a private API preview for selected developers.
- Multimodal input with visual reasoning
- Contemplating mode that runs agents in parallel
- Health answers built with input from over 1,000 physicians
- Trained with thinking-time penalties to use fewer tokens
Who it suits. People using Meta AI, and developers following Meta's move from Llama to the Muse models.
