#!/usr/bin/python3
import sys
import requests
 
def chat_with_model(token,model,question):
    url = 'https://gpt.ntnu.no/api/models/chat-completion'
    headers = {
        'Model': model,
        'Authorization': f'Bearer {token}',
        'Content-Type': 'application/json'
    }
    data = {
      "model": model,
      "messages": [
        {
          "role": "user",
          "content": question
        }
      ]
    }
    response = requests.post(url, headers=headers, json=data)
    return response.json()
 
my_api_key = sys.argv[1]
my_model = sys.argv[2]
my_question = sys.argv[3]
answer = chat_with_model(my_api_key, my_model, my_question)
print(answer)

Output example:

$ python3 chat.py '…..API…TOKEN………' 'gpt-oss-120b' 'What is the tallest mountain in Norway? Answer with name only.'
