Evidence boundaries

Organisation listings identify a reviewed canonical record. Model listings show an association in the source register; they do not by themselves establish model creation, current API availability, hosting location or infrastructure ownership.

Profile note

The most transparent large open model in Europe and Switzerland's national AI project: Apertus publishes not only weights but training data composition, recipes and intermediate checkpoints under Apache-2.0, trained entirely on the publicly owned CSCS Alps supercomputer across 1,000+ languages including Swiss German and Romansh. It has no commercial arm and no pricing of its own — monetisation happens downstream at Swisscom, Infomaniak and the Public AI Inference Utility. The single most important reference point for what 'sovereign European AI' can mean in practice.
