Summary A

Muse Ember costs $0.10 per million input tokens and $0.50 per million output tokens for shorter prompts, while sitting on the Artificial Analysis efficiency frontier: no model scores higher for less per task. For production agents, it is a serious default candidate for high-volume tool calls, routing, extraction, coding subtasks, and long-document parsing, but you should benchmark at your actual reasoning level because token price alone will not predict total task cost.
