What happened

Meta has introduced Muse Spark 1.1, made it available in Meta AI, and opened a public preview of the Meta Model API for developers.

The facts in this brief are limited to what the named organizations published. Product capabilities, research results, and future plans are attributed to those sources and should be read as their claims unless independently reproduced.

The useful context

Meta describes Muse Spark 1.1 as a multimodal reasoning model for agentic, coding, and computer-use tasks and has opened its Model API in public preview.

Why this matters
A new developer API gives Meta a more direct role in the agent-model market. Performance and safety claims in the launch material remain Meta’s own and need outside evaluation.
