How do I stream a reply in Python?

Set stream=True and loop over the chunks. Text arrives in choices[0].delta.content.

import os
from openai import OpenAI

client = OpenAI(
    base_url="https://api.gateway.clatterlabs.xyz/v1",
    api_key=os.environ["CLATTER_API_KEY"],
    default_headers={"X-Clatter-Account": os.environ["CLATTER_ACCOUNT_ID"]},
)

stream = client.chat.completions.create(
    model="supercosmos-flash",
    messages=[{"role": "user", "content": "Explain recursion in two sentences."}],
    stream=True,
)
for chunk in stream:
    if chunk.choices and chunk.choices[0].delta.content:
        print(chunk.choices[0].delta.content, end="", flush=True)
print()

Check chunk.choices before indexing: the optional usage chunk has an empty choices list.

The client setup above (base URL, key and the X-Clatter-Account header) is the same in every Python example; see Set up the Python SDK. Full parameter list: Create a chat completion.
