Overview
- Meta released Muse Ember on Monday, November 9, 2026, positioning it as the Muse family’s lightest, most cost‑efficient reasoning model for developers.
- Ember’s list prices are $0.10 per million input tokens and $0.50 per million output tokens, rates aimed at making routine agent tasks cheaper to run at scale.
- Meta says Ember supports multimodal inputs — text, images, audio, and video — and is designed for repeated agent work such as tool calls, routing, extraction, coding subtasks, and long‑document parsing.
- The lowest pricing closely matches Meta’s discounted Contributor tier, which lowers costs in exchange for permission to use customers’ interaction data to improve future models, a tradeoff that raises privacy and compliance questions for regulated users.
- Independent, public benchmarks and full technical disclosures for Ember remain limited even as Meta cites composite vendor benchmarks showing cost‑performance advantages, leaving enterprises to weigh savings against uncertain real‑world performance.
