Thanks @twhite54! It seems that you're running through Azure. Could you try running the following program, replacing the key with your Azure key?

import litellm

messages = [
    {"role": "system", "content": "Respond in pirate speak."},
    {"role": "user", "content": "What is 2+2?"},
]

response = litellm.completion(
  api_key="sk-XXX",
  model="azure/o1-preview",
  messages=messages,
)

print(json.dumps(response.model_dump(), indent=2))

If this fails, then it's probably a problem that should be reported directly to LiteLLM: https://github.com/BerriAI/litellm/

If it works, then we'll need to investigate further, as it may be an error on our side.
