Meta Releases Lightweight Model Muse Ember, Now Available on Meta Model API

Meta has released its smallest and most efficient model, Muse Ember, now available on the Meta Model API, priced at $0.10 per million input tokens and $0.50 per million output tokens. The model is aimed at complex reasoning execution and everyday agent work: it can carry workflows across applications, call tools in sequence, run tests, and make targeted code fixes. It supports a 1M token context window and native understanding of text, images, audio, and video. Meta says that on the Artificial Analysis Intelligence Index, its performance is comparable to Claude Haiku 5.5, but its cost per task is about one-third of the latter's, and it scores higher than GPT-6 Luna under every reasoning setting.
