What Aleph Alpha offers on sovereignty

Its flagship model is Kolibri, which it describes as its specialised sovereign large language model for business-critical environments and its new sovereign model for the public sector, available through an API. The site shows case studies for a government agency, a global chip manufacturer and an automotive supplier, and logos including Bundesagentur für Arbeit, Deutsche Bank, Infineon and SAP⁠1Aleph AlphaAleph Alpha.

The home page we read does not describe deployment options such as on-premises or air-gapped operation, and it publishes no prices. Buyers who need those answers should request them before shortlisting.
