Intergovernmental organisation; the corporate HQ-Europe badge is not applicable.
Evidence boundaries
Organisation listings identify a reviewed canonical record. Headquarters is independent of incorporation, registered offices, ownership, hosting and runtime. 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 consequential European non-text foundation model that almost never appears in AI directories. ECMWF is an intergovernmental body that in February 2025 made a machine-learned model (AIFS) part of its operational forecast suite — the first major weather centre to do so — and publishes both the weights and the training configs openly under CC-BY-4.0. A rare case where the European public sector, not a startup, holds the frontier in a modality.
