Muse Spark 1.3 (Contributor)
Muse Spark 1.3 (Contributor) runs Meta's Muse Spark 1.3 multimodal reasoning model at heavily discounted Contributor-mode pricing, in exchange for permission for Meta to use request content to train future models. It does not support the maximum reasoning effort level, so choose standard Muse Spark 1.3 for workloads that need it. Best suited to high-volume development, experimentation, and non-sensitive workloads where data contribution is acceptable.
