Meta AI launches Muse Ember, a cost-effective model for high-volume tasks

Meta AI Research has launched Muse Ember, a new, cost-effective model designed for high-volume tasks like tool calls and agentic workflows. Priced at $0.10 per 1M tokens for input and $0.50 for output, Ember is positioned as the workhorse model for repetitive tasks, complementing existing models like Muse Wonder for complex problems and Muse Spark for coding. A key detail for users is that the default reasoning effort is set to maximum, which could lead to unexpected costs, and the model has a 200K token input cliff that applies to the entire request if exceeded. AI

IMPACT This release offers a lower-cost option for common AI tasks, potentially accelerating adoption of agentic workflows by reducing operational expenses.
