FAQ
Can I run Muse-Spark-Open-816B-A42B on a dedicated deployment in Europe?
Yes. sference deploys Muse-Spark-Open-816B-A42B on GPU capacity reserved for you, behind a private endpoint, with every request processed on European GPUs and logged in your audit trail. Tell us your expected volume and latency targets with the form on this page and we come back with a sizing and a quote.
How many GPUs does Muse-Spark-Open-816B-A42B need?
The published checkpoint is about 1.64 TB (BF16), so loading it takes at least 3 nodes × 8 GPUs with 80 GB of memory each, or 2 nodes × 8 GPUs with 141 GB each. Long contexts and high concurrency need more for the KV cache; quantization needs less. You don't pick hardware on sference: you choose a performance tier and we size the deployment.
Is Muse-Spark-Open-816B-A42B licensed for commercial use?
Muse-Spark-Open-816B-A42B is published under the Custom license license. Custom license from the model maker (muse-model-license). Review the terms on the model page before production use.
