What is distinctive about this API

European provider with EU data residency, which is frequently the deciding factor rather than any model capability.
Dedicated code models and an embeddings endpoint sit alongside the chat models.
Several models ship under Apache 2.0, so the hosted API and a self-hosted deployment can run the same weights.

Constraints worth knowing first

Open-weight and commercial models carry different licences — check before assuming a model can be self-hosted.
Function-calling support varies across the family; the smaller models are more limited than the flagships.
