+:::tip Azure Foundry Support
+
+Claude models are also available via Microsoft Azure Foundry. Use the `azure/` prefix instead of `anthropic/` and configure Azure authentication. See the [Azure Anthropic documentation](../providers/azure/azure_anthropic) for details.
+
+Example:
+```python
+response = completion(
+    model="azure/claude-sonnet-4-5",
+    api_base="https://<resource-name>.services.ai.azure.com/anthropic",
+    api_key="your-azure-api-key",
+    messages=[{"role": "user", "content": "Hello!"}]
+)
+```
+
+:::

 ### Custom API Base
 
 When using a custom API base for Anthropic (e.g., a proxy or custom endpoint), LiteLLM automatically appends the appropriate suffix (`/v1/messages` or `/v1/complete`) to your base URL.
