Additional Use Grant: You may make use of the Licensed Work, provided that
                      you do not use it for a Competing Use. A "Competing
                      Use" means offering the Licensed Work (or a derivative
                      of it) to third parties as a hosted or managed service
                      that competes with Sipsa Labs' commercial offerings.

                      Non-production use, internal research, individual use,
                      and use by any commercial entity with annual gross
                      revenue under US $1,000,000 are NOT Competing Uses and
                      are permitted without a separate commercial license.

Change Date:          Four years from the date each version of the Licensed
                      Work is first published. For version 0.6.13, the

Notice

The Business Source License (this document) is not an Open Source license.
However, the Licensed Work will eventually be made available under an Open
Source License, as stated in this License.

The Additional Use Grant above does not extend to the patent-pending
compression methodology that produces the pre-compressed model artifacts;
that methodology is the subject of pending U.S. provisional patent
applications and is not licensed by this document. Pre-compressed model
artifacts distributed via the Hugging Face Hub remain governed by their
upstream teacher model's license plus this project's patent terms.
