Terms of Service

Last updated: February 2026

Use of service

MARC27 publishes software, models, datasets, and research under a range of licenses. Your rights to use any item — including whether it may be used commercially — are governed by the license that applies to that item. Some work is released under permissive open-source licenses (MIT, Apache-2.0, CC-BY) and may be used freely, including commercially. Other work is released under the source-available MARC27 Source-Available License, which permits inspection and non-commercial research but not commercial use without a separate written agreement. See the licenses overview for details.
