Meta Launches Muse Ember: The Little Model That Does the Busywork
Meta's smallest, cheapest Muse model is built for the jobs agents repeat all day.

Meta released a new Muse model on November 9 called Ember. It's the smallest and most efficient model Meta has made under the Muse name.
Ember isn't built to be the genius in the room. It's built for the work agents repeat all day: tool calls, coding subtasks, routing, and pulling information out of long documents.
Meta's own way of putting it: Muse Wonder “tackles the hardest problems, while Muse Ember handles everyday agent workloads.” The big model thinks. Ember runs.
The price is 10 cents per million input tokens and 50 cents per million output tokens. That's in line with other small models — but the independent testers at Artificial Analysis found Ember gets the same score as Claude Haiku 5.5 for about a third of the cost per task, because it uses fewer tokens to get there.
Right now Ember is for builders: it's available through Meta's Model API and in Muse Code, Meta's coding tool.
Agents just got cheaper to run. The busywork layer is where the volume is — and volume is where the cost was.
