Meta says Muse Ember delivers more capability per dollar than Claude Haiku 5.5 and GPT-6 Luna at every reasoning level. Results vary by task type: Muse Ember leads in most of Meta’s own tests, while Haiku scored 34.9% versus Muse Ember’s 27.2% on the FrontierCode 2.0-AA benchmark for real-world coding tasks.
Access and capabilities
The model works with text, images, audio and video, and can process up to one million tokens at a time. It is already available through Meta Model API and Muse Code. Pricing is $0.10 per million input tokens and $0.50 per million output tokens.
Dataist’s take: the results show that Muse Ember’s low cost does not guarantee it will lead across every task type: it fell behind Haiku on a real-world coding test. Models like these should therefore be compared with the specific work they are intended to do in mind.
