Introducing Muse Spark 1.1
Summary
Meta's announcement of Muse Spark 1.1, a multimodal reasoning model for agentic tasks from Meta Superintelligence Labs. It is offered through the new Meta Model API (public preview) and in "Thinking" mode in the Meta AI app and on meta.ai. The post does not mention open weights or Llama.
Key points
- Improves on Muse Spark in tool use, coding, and multimodal understanding.
- 1M-token context window, which the model can manage actively.
- Available only through the API and Meta's apps. The post mentions no weights, licence, or prices.
- The Muse family also includes Muse Image and Muse Video (announced 2026-07-07).
Why it matters
Meta's newest model line is API-first, not open-weight. That partly answers whether Meta has released anything after Llama 4: it has released new models, but not as open weights.
