-    the Agents SDK with `model` set to the requested model name, e.g. an Azure deployment
-    name. Only the provider chunks carry the model that actually responded.
+    The default `OpenAIResponsesModel` is not affected: its terminal streaming event carries
+    the model that responded. This only applies to the opt-in Chat Completions code paths,
+    i.e. an explicit `OpenAIChatCompletionsModel` (commonly used with Azure OpenAI and
+    OpenAI-compatible providers), `set_default_openai_api("chat_completions")`, and
+    `LitellmModel`. For those, the Agents SDK synthesizes the streamed response with `model`
+    set to the requested model name, e.g. an Azure deployment name, so only the provider
+    chunks carry the model that actually responded.
