OpenAI API error: "Module 'openai' has no attribute 'ChatCompletion', did you mean 'Completion'?"

I can't seem to figure out what the issue is here, I am running version 0.28.1:

from what I have read I should be using ChatCompletion rather than Completion as that's what gpt-4 and 3.5-turbo supports.

response = openai.ChatCompletion.create(
    prompt=question,
    temperature=0,
    max_tokens=3700,
    top_p=1,
    frequency_penalty=0,
    presence_penalty=0,
    stop=None,
    model="gpt-4",
)

Looking at other answers I can also tell you that my file isn't named openai.py or anything like that.

Thanks for any help in advance.

First of all, be sure you have an up-to-date OpenAI package version.

If not, upgrade the OpenAI package.

Python:

pip install --upgrade openai

NodeJS:

npm update openai

The code posted in your question above has a mistake. The Chat Completions API doesn't have the prompt parameter as the Completions API does. Instead, it has the messages parameter. See the official OpenAI documentation.

Try the following:

import os
import openai
openai.api_key = os.getenv("OPENAI_API_KEY")

completion = openai.ChatCompletion.create(
  model = "gpt-4",
  messages = [
    {"role": "system", "content": "You are a helpful assistant."},
    {"role": "user", "content": "Hello!"}
  ]
)

print(completion.choices[0].message)
