openai.error.InvalidRequestError: This is a chat model and not supported in the v1/completions endpoint. Did you mean to use v1/chat/completions?

Heres my code:

from django.shortcuts import render
from django.http import JsonResponse
import openai

openai_api_key = '■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■j5LuDiSb'
openai.api_key = openai_api_key

def ask_openai(message):
    response = openai.Completion.create(
        model="text-davinci-003",
        prompt = message,
        max_tokens=150,
        n=1,
        stop=None,
        temperature=0.7,
    )  
    answer = response.choice[0].text.strip()
    return answer

def chatbot(request):
    if request.method == 'POST':
        message = request.POST.get('message')
        response = ask_openai(message)
        return JsonResponse({'message': message, 'response': response})
    return render(request, 'index.html')

I dont know whats going on please help im new. If you need more code I can provide some more.

I tried changing it to gpt-4 but it makes the same problem. I think it might be a bug.

Answer 1

you have a typo in ask_openapi. it should be choices

   answer = response.choices[0].text.strip()

But I do not think that this is the reason. model="text-davinci-003", is used with the Completions api. ask_openai function is built correctly.

there is an open github issue. some updated the openai library and solved the issue

 pip install --upgrade openai.

it might be due to a bug in openai library. if you installed the latest version, try to donwgrade it
