Meta Releases Muse Ember to Cut AI Agent Costs by 3x
Meta launched Muse Ember , its smallest model, built for agent subtasks and tool calls. Priced at $0.10 per 1M input tokens, $0.50 per 1M output, $0.004 cached input. Matches Claude Haiku 5.5 on Intelligence Index at roughly one-third the cost per task.
Takeaways
- Meta launched Muse Ember , its smallest model, built for agent subtasks and tool calls.
- Priced at $0.10 per 1M input tokens, $0.50 per 1M output, $0.004 cached input.
- Matches Claude Haiku 5.5 on Intelligence Index at roughly one-third the cost per task.
- 1M-token context, 512K output, native text, image, audio, and video input.
- Leads on AutomationBench (37.8%), Terminal-Bench (40.9%), OSWorld 2.1 (69.5%); trails Haiku on FrontierCode 2.0.
- First model distilled from Muse Wonder Full; available now as
muse-ember-1.0.
Meta Superintelligence Labs has released Muse Ember, the smallest model in its Muse family, for tool calls, routing, extraction, coding subtasks, and long-document parsing. The hosted model is available as muse-ember-1.0 through Muse Code and the Meta Model API.
Meta’s launch post positions Ember as a subagent that can handle hundreds of intermediate steps without sending every request to a larger frontier model. That approach could lower the cost of agent systems, provided Ember maintains sufficient accuracy and does not trigger expensive retries.
