Make a request

You can paste the following command into your terminal to run your first API request. Make sure to replace YOUR_API_KEY with your secret API key.

This request queries the model to complete a text prompt starting with "Say this is a test" using the gpt-3.5-turbo model. You should receive a response similar to the following:

{
   "id": "chatcmpl-abc123",
   "object": "chat.completion",
   "created": 1677858242,
   "model": "gpt-3.5-turbo-0301",
   "usage": {
      "prompt_tokens": 13,
      "completion_tokens": 7,
      "total_tokens": 20
   },
   "choices": [
      {
         "message": {
            "role": "assistant",
            "content": "\n\nThis is a test!"
         },
         "finish_reason": "stop",
         "index": 0
      }
   ]
}

Now you’ve generated your first chat completion. We can see that the finish_reason is stop, which means the API returned a complete response generated by the model. In the above request, we generated only one message, but you can configure the n parameter to generate multiple message options.

In this example, gpt-3.5-turbo is used primarily for traditional text completion tasks. The model is also optimized for chat-based applications.
