Data residency
Use a region prefix on the model name to pin the request to a specific Azure region. Bare aliases (e.g. gpt-5-codex) round-robin across all regions — use a prefix when you need a request to stay inside a jurisdiction.
Available regions
| Prefix | Region | Jurisdiction |
|---|---|---|
| azure-eus2/ | East US 2 | United States |
| azure-eus/ | East US | United States |
| azure-scus/ | South Central US | United States |
| azure-wus3/ | West US 3 | United States |
| azure-swc/ | Sweden Central | European Union |
| azure-weu/ | West Europe | European Union |
| azure-frc/ | France Central | European Union |
| azure-aue/ | Australia East | Australia |
Example
# Stay inside the EU
model = "azure-swc/gpt-4.1"
# United States only
model = "azure-eus2/Llama-4-Maverick"
