Muse Spark 1.1 is a Meta large language model, announced in July 2026, that powers the Meta AI assistant and is built to plan and act on tasks.
In plain words
Muse Spark is Meta's model series from its Meta Superintelligence Labs; the first version launched in April 2026. Version 1.1 is designed to make plans, work with your apps and carry a task through to the end. With it, Meta AI can do things such as prepare a daily briefing from your calendar or research a topic across the web. It also powers Muse, Meta's personal AI agent.
A quick example
Meta gives an example of asking Meta AI for a first half-marathon plan. It builds a week-by-week schedule, fits it around your availability and sends that week's plan every Monday morning.
