[Python] Why the new OpenAI model o1-preview doesn't support system role?

Apparently, the new model OpenAI o1-preview doesn't support system role:

import os
from openai import OpenAI

client = OpenAI(api_key=os.environ['OPENAI_API_KEY'])

messages = [
{"role": "system", "content": "You are a helpful assistant."},
{"role": "user", "content": "Hello, how are you?"}
]

response = client.chat.completions.create(
model='o1-preview',
messages=messages,
temperature=0.0,
max_tokens=500,
stream=False
)

response_message = response.choices[0].message.content
print(response_message)


out:

BadRequestError: Error code: 400 - {'error': {'message': "Unsupported value: 'messages[0].role' does not support 'system' with this model.", 'type': 'invalid_request_error', 'param': 'messages[0].role', 'code': 'unsupported_value'}}


Moreover, the parameters temperature and max_tokens aren't supported either!
