Overview
- Meta launched Muse Ember on Monday, Nov. 9, 2026, and made it available immediately on Muse Code and the Meta Model API under the model ID muse-ember-1.0.
- Ember is priced at $0.10 per million input tokens and $0.50 per million output tokens, and Google Cloud and Oracle Cloud are offering the model through their managed APIs to reach enterprise customers.
- The model accepts text, images, audio, and video, supports a 1 million‑token context window and up to 512,000 output tokens, and is built to handle high‑volume agent subtasks like tool calls, extraction, routing, and coding steps.
- Meta published Artificial Analysis and internal benchmarks that show Ember matching or beating rivals on cost‑per‑task versus Anthropic’s Claude Haiku 5.5 and OpenAI’s GPT‑6 Luna, but independent, third‑party validation of those claims is not yet widely available.
- Meta says Ember was trained using Muse Wonder Full and is meant to be paired with larger Muse planning models; the company also highlights safety testing under its Superintelligence Scaling Framework and offers discounted Contributor pricing that may involve data sharing for model training, a trade‑off developers will need to weigh.
