Muse Spark Open: a custom Muse Model License with a $20 million revenue threshold for model-as-a-service, required attribution and broad derivative definitions. Muse Glimmer: Apache 2.0. Qwen3.8 Max: weights freely downloadable, though training data and methods may not be revealed. Beam: open-weight, from a lab that has said it keeps datasets and training pipelines proprietary.
The differences matter for resellers and for companies planning to fine-tune or distill. Counsel should review each license, and the summaries here come from press reports.
