Meta releases low-cost Muse Ember AI model for repetitive agent tasks
Meta has released Muse Ember, its smallest and most cost-efficient AI model in the Muse family.
The model is designed for AI agents that repeat tasks such as calling tools, extracting information, helping with code and parsing long documents.
Meta says it can process text, images, audio and video, with a context window of up to one million tokens.
On an Artificial Analysis benchmark, Ember scored 36 and was estimated to cost $0.14 per task, compared with $0.41 for Anthropic’s Claude Haiku 5.5 at the same score.
Meta’s plan is for larger models such as Muse Wonder to plan complex work, while Ember handles the repeated steps at lower cost.
Developers can use Ember through Meta Model API and Muse Code; Meta has not said whether it will add the model to its consumer AI assistant.
Meta introduced Muse Ember on November 9 as its smallest and most cost-efficient AI model.
The model is designed for repetitive tasks in AI agent workflows, including tool calls, coding subtasks, information extraction and long-document parsing.
Meta says Ember can process text, images, audio and video, with a context window of up to 1 million tokens.
Artificial Analysis gave Ember an Intelligence Index score of 36 and estimated its cost at about $0.14 per task.
Developers can access the model through Meta Model API and Muse Code as muse-ember-1.0.
