Sends a chat prompt to the OpenAI API using streaming mode and reconstructs the full response by concatenating incoming chunks.

Stream and Assemble OpenAI Chat Response in Python.swift

from openai import OpenAI

client = OpenAI()

stream = client.chat.completions.create(
    model="gpt-4-1106-preview",  # or "gpt-4.1" if that's valid in your setup
    messages=[
        {
            "role": "user",
            "content": "Say 'double bubble bath' ten times fast.",
        },
    ],
    stream=True,
)

full_response = ""

for chunk in stream:
    if chunk.choices and chunk.choices[0].delta.content:
        full_response += chunk.choices[0].delta.content

print(full_response)

# Sample output
#
# I'm an AI text-based model, so I can't physically say things aloud. However, you're welcome to give it a try! Rapid repetition of "Double bubble bath" can be quite a tongue twister.
