Corti Models is served differently depending on your project’s region.
The same model ID does not return the same model in both regions. If you run evaluations or pin a model version, treat EU and US as separate targets: a result from a US project doesn’t tell you anything about the EU-hosted model behind the same ID, or vice versa.

​
Choosing a region

Your project’s region is set when you create it in the Corti Console, and every API client created under that project inherits it. See Environments & Tenants for how regions work across the rest of the Corti API.
