About Muse Spark 1.3 Contributor

Muse Spark 1.3 Contributor is the Contributor-tier catalog ID (muse-spark-1.3-contributor) of Muse Spark 1.3 on Meta Model API. Official models page lists it as a distinct Model ID on the Contributor tier with the same 1,048,576-token context and the same input modalities as muse-spark-1.3 (text, image, video, audio*, PDF) and text output. First-party pricing page lists it with its own Contributor rates. Heavily discounted token pricing in exchange for permission to use prompts and completions to train future Meta models. Audio understanding in 1.3 is currently not fully supported. Not a separately published checkpoint or weights drop.
