+The Python Slack SDK provides a [`chat_stream()`](https://docs.slack.dev/tools/python-slack-sdk/reference/web/client.html#slack_sdk.web.client.WebClient.chat_stream) helper utility to streamline calling these methods. Here's an excerpt from our [Assistant template app](https://github.com/slack-samples/bolt-python-assistant-template):
+
+```python
+streamer = client.chat_stream(
+    channel=channel_id,
+    recipient_team_id=team_id,
+    recipient_user_id=user_id,
+    thread_ts=thread_ts,
+)
+
+# Loop over OpenAI response stream
+# https://platform.openai.com/docs/api-reference/responses/create
+for event in returned_message:
+    if event.type == "response.output_text.delta":
+        streamer.append(markdown_text=f"{event.delta}")
+    else:
+        continue
+
+feedback_block = create_feedback_block()
+streamer.stop()

 ## Formatting messages with Block Kit {#block-kit}
 
 Messages posted from apps can contain more than just text; they can also include full user interfaces composed of blocks using [Block Kit](/block-kit).
