     The example above uses `ChatAnthropic`, which is already supported by `init_chat_model`. This pattern is shown to illustrate how to manually instantiate a model not available through init_chat_model.
 
+## Disable streaming
+
+To disable streaming of the individual LLM tokens, set `disable_streaming=True` when initializing the model:
+
+=== "`init_chat_model`"
+
+    ```python
+    from langchain.chat_models import init_chat_model
+
+    model = init_chat_model(
+        "anthropic:claude-3-7-sonnet-latest",
+        # highlight-next-line
+        disable_streaming=True
+    )
+    ```
+
+=== "`ChatModel`"
+
+    ```python
+    from langchain_anthropic import ChatAnthropic
+
+    model = ChatAnthropic(
+        model="claude-3-7-sonnet-latest",
+        # highlight-next-line
+        disable_streaming=True
+    )
+    ```
+
+Refer to the [API reference](https://python.langchain.com/api_reference/core/language_models/langchain_core.language_models.chat_models.BaseChatModel.html#langchain_core.language_models.chat_models.BaseChatModel.disable_streaming) for more information on `disable_streaming`

 ## Adding model fallbacks
 
 You can add a fallback to a different model or a different LLM provider using `model.with_fallbacks([...])`:
