Meta Sells Agent Work by the Dollar
A model that scores just below its predecessor costs a seventeenth as much per task.
Meta Superintelligence Labs released Muse Ember on 9 November 2026, a lightweight agent model with a one-million-token context window, 512,000-token maximum output and native support for text, images, audio and video. It scores 36 on the Artificial Analysis Intelligence Index, one point below its own Spark 1.3 at 37, while an estimated $0.14 per task replaces $2.39, roughly one-seventeenth. API pricing is $0.10 per million input tokens and $0.50 per million output. On AutomationBench it reaches 37.8%, against 20.2% for GPT-6 Luna and 13.9% for Claude Haiku 5.5. The architectural implication is that flagship planning plus cheap execution becomes the default way to run agent fleets.
