# Streaming Messages

Streaming messages enables users to receive the model's responses in chunks, rather than waiting for the compete response to be generated. This is done by incrementally transmitting chunks of content to the user. This feature enables users to:

* **Instant Responses:** Content appears progressively without waiting for the full output.
* **Enhanced User Experience:** Minimizes waiting time and offers immediate feedback.
* **Lower Latency:** Information is delivered as it’s created, reducing perceived delay.
* **Dynamic Handling:** Allows real-time processing and display while data is being received.

#### Parameter Settings

To enable streaming, set `stream=True`.

for chunk in response:
