Muse Spark

MetaProprietaryPending Human Review

Muse Spark is the first model developed by Meta Superintelligence Labs in the Muse family. It is a proprietary multimodal reasoning model with tool use, visual reasoning, and multi-agent orchestration, initially released through Meta AI on the web and in the app. It offers different response and reasoning modes for everyday questions and harder tasks. Its release marked a new training program rather than an open Llama checkpoint. Architecture and parameter count are not publicly disclosed, and planned future open-weight releases do not apply to this model.
