Meta says it matches Anthropic's Claude Haiku 5.5 on Artificial Analysis's Intelligence Index at 36 points, at about one-third the cost per task, roughly $0.14 against $0.41. It supports a 1 million token context window and is available through the Meta Model API and Muse Code.","whyItMatters":"Meta is pricing Muse Ember at the low end of the agent market and conceding the hardest coding tasks to rivals, which puts the competition on cost per task rather than raw benchmark scores.","webCardHtml":"\u003cp\u003eMuse Ember is built for the work agents do over and over: reading files, running tests, editing code, pulling data out of long documents.
