Meta has switched its consumer assistant onto Muse Spark 1.1 and turned it into an agent, the company said on Friday. Meta AI can now make plans, connect to email and calendar applications, build slide decks and handle multi-step tasks on a user's behalf.
What changed
The assistant gained daily briefings, real-time research synthesis and persistent task management that does not require re-prompting between steps. Connectors for Gmail and Google Calendar are part of the release. Research tasks can run for several minutes rather than returning immediately.
The model underneath
Muse Spark 1.1 supports prompts up to 1 million tokens and can spin up groups of AI agents working together. The model itself is not new — it launched on July 9. What is new is Meta putting it behind the assistant that ships inside Facebook, Instagram and WhatsApp.
Limited, for now
The rollout reaches only a small number of markets on web and mobile, with WhatsApp arriving in a few weeks. Meta published no benchmarks and no adoption figures with the announcement — claims circulating that the model ranked first on particular agent benchmarks do not appear in Meta's own materials.
The permissions question
An assistant that reads your inbox and writes to your calendar needs standing access to both. Meta has not detailed what the agent retains from those connectors, for how long, or whether task history feeds model training. On a surface with billions of users, that consent screen is the actual product decision.
The distribution question
OpenAI and Anthropic have shipped capable agents to tens of millions of users. Meta is shipping a less capable one to a surface with billions. Which constraint binds first — capability or reach — is the experiment now running.
