Meta rolled out new models for Muse on November 6, trained using Muse Wonder, its most capable model. They're going to everyone who uses Muse and Meta AI — no upgrade, no extra cost.
The headline number is memory. Meta says the new models show a 2.4× reduction in forgetting critical information, and a 67% improvement in getting unstuck when a task hits a snag. Those are Meta's own figures from its own tests.
On Meta's memory test, the new model used the right key details in 90% of tasks, up from 76%.
Forgetting is the quiet problem with AI agents. A job starts strong, then loses the thread halfway through and you're back to repeating yourself.
Models that hold the thread longer can take bigger jobs with fewer check-ins. That's the whole point of an agent.
The agents you set up today get better on their own. Same prompts, stronger engine.
