Model licences

The canonical licence ontology behind the openness classification. Permissions are read from each licence text; a dash means the text is ambiguous — never assumed.

Permissions are read from the licence text (null = the text is ambiguous). Counts cover canonical models only. Hosting restrictions / acceptable-use: “Yes — restricted” means the clause exists.

Commercial use: Use in a commercial product or service without a separate agreement.
Redistribution: Sharing the licensed weights or code with third parties.
Derivatives: Publishing fine-tunes, merges, quantisations or other modified versions.
Hosting restrictions: Restrictions on serving the model as a hosted API (user caps, field-of-use, competitor clauses). Yes = restrictions exist.
Acceptable-use policy: The licence attaches an acceptable-use policy / behavioural restrictions. Yes = a policy applies.
Attribution: Attribution or notice requirements.
