Meta has introduced Muse Ember, the smallest reasoning model in its Muse lineup, via the Meta Model API. The model is designed for developers prioritizing cost-efficiency in their AI workflows.
Pricing for Muse Ember is set at $0.10 per million input tokens and $0.50 per million output tokens. This structure is significantly lower than the Muse Spark 1.3 model, which costs approximately $1.25 per million input tokens and $4.25 per million output tokens.
The pricing for Ember aligns with the Contributor tier of the Meta Model API. By choosing this option, developers receive discounted rates in exchange for allowing Meta to use their interaction data for future model training.
Muse Ember joins a family of multimodal models developed by Meta Superintelligence Labs, which includes larger variants like Muse Spark and Muse Wonder. The Muse series was initiated in April 2026 with the release of Muse Spark.
As of October 2026, no independent performance benchmarks or technical specifications for Muse Ember have been publicly released. This lack of data makes it difficult to compare its capabilities against other models in the market.
