Meta introduced Muse Ember, its smallest and most efficient model, aimed at the repetitive execution work agents do all day: tool calls, coding subtasks, routing, extraction, and long-document parsing.
- On the Artificial Analysis Intelligence Index, Muse Ember matches or beats Claude Haiku 5.5 and GPT-6 Luna at every reasoning setting on intelligence-per-dollar: its max setting scores 35.8 at $0.136 per task, while Haiku 5.5's 36.2 costs $0.411.
- Meta claims it sits on the efficiency frontier — no model scores higher for less per task.
- The launch rounds out Meta's lineup across price and performance tiers.
