Remember that user and instruction messages can guide the model toward desired responses.

{
  "messages": [
    {"role": "user", "content": "tell me a joke"},
    {"role": "assistant", "content": "Why did the chicken cross the road? To get to the other side!"}
  ]
}

Handling Responses

Once you send a request to the API, you will receive a JSON response containing various details. You should focus on the choices[0].text field containing the model’s generated output. Example of a response structure:

{
 "id": "chatcmpl-6p9XYPYSTTRi0xEviKjjilqrWU2Ve",
 "object": "chat.completion",
 "created": 1677649420,
 "model": "gpt-3.5-turbo",
 "usage": {
   "prompt_tokens": 56,
   "completion_tokens": 31,
   "total_tokens": 87
 },
 "choices": [
   {
    "message": {
      "role": "assistant",
      "content": "How about another joke? What do you get when you cross a snowman with a vampire? Frostbite!"
    },
    "finish_reason": "stop",
    "index": 0
   }
  ]
}

When parsing the response, use the following code:

response_text = response['choices'][0]['message']['content']

In summary:

  • Use clear and concise instructions in prompts for optimal results.
  • Structure conversations using lists of messages with roles and content.
  • Focus on choices[0].text to extract the model-generated output from API responses.
