CometAPI でエラーコードとリトライをどのように扱えばよいですか？

import os
import random
import time
from openai import APIError, OpenAI, RateLimitError

client = OpenAI(
    api_key=os.environ["COMETAPI_KEY"],
    base_url="https://api.cometapi.com/v1",
)

for attempt in range(5):
    try:
        response = client.chat.completions.create(
            model="your-model-id",
            messages=[{"role": "user", "content": "Say hello."}],
        )
        print(response.choices[0].message.content)
        break
    except RateLimitError:
        delay = min(30, 2**attempt) + random.random()
        time.sleep(delay)
    except APIError as error:
        status_code = getattr(error, "status_code", None)
        if status_code in {500, 503, 504, 524}:
            delay = min(30, 2**attempt) + random.random()
            time.sleep(delay)
            continue
        raise
else:
    raise RuntimeError("The request failed after retries.")

  "choices": [
    {
      "message": {
        "role": "assistant",
        "content": "Hello."
      }
    }
  ],
