Muse Ember

Meta has released Muse Ember, the lightest and most cost-efficient model in its Muse family, designed for agent tasks such as tool calls, coding subtasks, routing, extraction and long document parsing. Meta cites Artificial Analysis's composite benchmark to position it as cheaper and smarter than Anthropic's Haiku and OpenAI's Luna, and prices it at 10 cents per million input tokens. Ember accepts text, images and audio, and is intended to pair with the larger Muse Wonder model in an agentic harness. The page does not state licensing or availability terms.
