I am using Completions in openai library for python.

Something like this(simplified code just to understand what I am doing):

self.__response = self.client.chat.completions.create(
    model='gpt-4',
    messages=messages,
    stream=True
)

After this I just loop through chunks:

    for chunk in self.__response:
        text = chunk.choices[0].delta.content
        # Processing text here

Is it enough to just do break inside the loop to prevent server generating response and wasting tokens if I see that the response is not meeting my expectations? Or probably there is correct way to achieve this?

Thanks much for your help in advance.
