Licences
Of the 23, 6 are open weights, which is not the same as open source: the weights are published, but under the Gemma licence, which restricts some uses. Read it before self-hosting commercially. Another 17 are recorded here as proprietary: access is through an API, priced by the token. Licences are as recorded in this catalogue: check the maker's own terms before relying on one.
