Latest update (11-09 20:38): Meta introduces Muse Ember, a low-cost AI model for agents

Overview: Meta releases Muse Ember, its smallest and cheapest model, for tool calls, coding subtasks, routing, extraction and long document parsing. It costs $0.10 per million input tokens and $0.50 per million output tokens on the Meta Model API and in Muse Code, and Vercel says it is available on AI Gateway. SiliconANGLE reports a 1 million token context window.

Artificial Analysis reports that Muse Ember (max) scores 36 on its Intelligence Index at $0.14 per task, the lowest cost of any model at that score or higher, and matches Claude Haiku 5.5 (max) on score at about a third of the cost. Vals AI reports $0.15 per test on the Vals Index, the lowest of any model there, and about 15 minutes to finish its tests, the fastest of the top 12 models.

Artificial Analysis also reports weak knowledge results: Muse Ember reaches 21.1% accuracy on AA-Omniscience, the lowest among the similarly intelligent models it compared, because it declines to answer 64% of questions. Its hallucination rate is 17.4%, half that of Claude Haiku 5.5.
