+api_type = "azure"
+base_url = "https://{resource-name}.openai.azure.com"

+channel = "azure/gpt-4o"
+worker = "azure/gpt-4o-mini"
+```
+
+Important notes:
+- `base_url` must end with `.openai.azure.com`
+- `api_version` and `deployment` are required fields
+- API key authentication is handled automatically via the `api-key` header
+- For Azure AI Foundry (accessing Anthropic, Llama, or other models through Azure's model catalog), use `api_type = "openai_chat_completions"` instead and configure the deployment endpoint accordingly
+
 Additional built-in providers include **Kilo Gateway**, **OpenCode Go**, **NVIDIA**, **MiniMax**, **Moonshot AI (Kimi)**, and **Z.AI Coding Plan** — configure with `kilo_key`, `opencode_go_key`, `nvidia_key`, `minimax_key`, `moonshot_key`, or `zai_coding_plan_key` in `[llm]`.

 ### Level 2: Task-Type Overrides
 
 Workers and branches are generic. Different tasks benefit from different models. The channel or branch specifies a task type when spawning, and the routing config maps task types to models.
