Meta released Muse Ember on November 9, 2026, its smallest Muse model, built for agentic work such as tool calls, routing, and long document parsing, with a 1 million token context window and native support for text, images, audio, and video.
Meta simultaneously made Muse Ember, Muse Wonder, and Muse Spark 1.3 available on Google Cloud. Priced at $0.10 per million input tokens for shorter prompts, Ember sits alongside GPT-6 Luna and Claude Haiku 5.5. Artificial Analysis found it on the efficiency frontier of their full leaderboard, meaning no model scores higher on their intelligence index at lower cost per task. Simon Willison noted Ember's output quality was comparable to Muse Wonder, which is 40x more expensive.
