Overview
- Meta launched Muse Ember on Monday, November 9, 2026, and made the model available as muse-ember-1.0 on the Meta Model API and Muse Code.
- The company priced Ember at $0.10 per million input tokens and $0.50 per million output tokens and says the model is built to run high‑volume agent subtasks such as tool calls, coding fixes, routing and document parsing.
- Ember supports a 1 million‑token context window, up to 512,000 output tokens, and native multimodal input for text, images, audio and video so agents can process large codebases and recordings in a single call.
- Meta published internal and Artificial Analysis benchmark comparisons that show Ember as cost‑efficient versus Anthropic’s Haiku and OpenAI’s Luna, but independent third‑party validation and long‑term safety or privacy audits remain limited or pending.
- The model is available through Meta’s API and Muse Code and has been added to Google Cloud and Oracle Cloud managed APIs, and its low Contributor-style pricing may trade lower cost for interaction data that Meta can use to train future models.
