Meta launches Muse Ember, a small AI model built for the repetitive work agents actually do

Meta introduced Muse Ember, its smallest and most efficient AI model, designed for routine agent tasks such as tool calling, small coding jobs, request routing, data extraction, and long-document processing. Meta says it scores 36 on the Artificial Analysis Intelligence Index at about $0.14 per task, versus $2.39 for the larger Muse Spark 1.3, though Claude Haiku 5.5 leads on real coding tasks in FrontierCode 2.0-AA at 34.9 percent to Muse Ember's 27.2 percent. The multimodal model handles up to one million tokens and is available through the Meta Model API and Muse Code at $0.10 per million input tokens and $0.50 per million output tokens.
