Meta’s private-weight Muse Ember is live at $0.10 and $0.50 per million tokens for routine agent tasks.

Meta Superintelligence Lab released Muse Ember, its smallest and most cost-efficient model, for tool calls, coding subtasks, routing, extraction, and long-document parsing. It is available only through the Meta Model API and Muse Code, with a 1 million-token context and up to 512,000 output tokens; weights stay private. List pricing is $0.10 per million input tokens and $0.50 per million output tokens. Simon Willison says that rate matches GPT-6 Luna and Claude Haiku 5.5 for shorter prompts, while longer-prompt pricing is less straightforward. Meta cites Artificial Analysis to claim more intelligence per dollar than Haiku and Luna; The Decoder puts cost near $0.14 per task, MarkTechPost near $0.136.
