Muse Spark at a glance
Muse Spark is the first model in Meta's new Muse series, a multimodal reasoning model that powers Meta AI, with API access limited to a private preview.
What changed with Muse Spark
On April 8, 2026, Meta announced Muse Spark, the first model in its new Muse series, built by Meta Superintelligence Labs. Meta describes it as small and fast, with reasoning for science, math, and health, plus understanding of images, charts, and camera input.
It offers Instant and Thinking modes, can launch parallel subagents on a complex question, and powers the Meta AI app and meta.ai, with rollout to WhatsApp, Instagram, Facebook, Messenger, Threads, and Meta's AI glasses. Meta says it hopes to open-source future versions, which signals this one is not open.

Why Muse Spark matters for businesses
API access is a private preview for select partners, and Meta published no benchmark numbers or pricing in the announcement. For businesses, the impact is mostly indirect for now: customers will meet Muse Spark inside Meta's messaging apps, where many small businesses already serve clients.
