Meta AI released Muse Ember, a new AI model designed for complex reasoning and repetitive tasks such as tool calls, coding subtasks, and long document parsing. Muse Ember is priced competitively with GPT-6 Luna and Claude Haiku 5.5 for shorter prompts ($0.10/million input tokens and $0.50/million output), but less competitively for longer prompts. Muse Ember has a unique pricing structure, with a threshold after which the price increases, and its pricing is between that of GPT-6 Luna and Claude Haiku 5.5. The model has six reasoning levels and is positioned on the efficiency frontier of the Artificial Analysis leaderboard, offering high efficiency at a relatively low cost.
