1. Create a file named .env in your enterprise itemizing.

2. Add the subsequent line to the .env file, altering your_api_key with the exact API key you copied earlier: CHAT_GPT_API_KEY=your_api_key.

3. In your Python code, load the API key from the .env file using the load_dotenv function from the python-dotenv bundle deal:

  import openai
  from openai import OpenAI
  import os
  from dotenv import load_dotenv

  
  load_dotenv()
  shopper = OpenAI(api_key=os.environ.get("CHAT_GPT_API_KEY"))

Phrase: Throughout the latest mannequin of the OpenAI Python library, it’s best to instantiate an OpenAI shopper to make API calls, as confirmed below. It’s a change from the sooner variationsthe place you may straight use world methods.

Now you’ve added your API key and your environment is prepared up and ready for using the OpenAI API in Python. Throughout the subsequent sections of this textual content, we’ll uncover interacting with the API and developing chat apps using this extremely efficient software program.

Keep in mind in order so as to add the above code snippet to every code half down below sooner than working.

Using the OpenAI API in Python

After loading up the API from the .env file, we’re capable of actually start using it inside Python. To utilize the OpenAI API in Python, we’re capable of make API calls using the patron object. Then we’re capable of transfer a sequence of messages as enter to the API and procure a model-generated message as output.

Making a simple ChatGPT request

1. Make sure you have carried out the sooner steps: making a digital environment, placing within the obligatory libraries, and producing your OpenAI secret key and .env file throughout the enterprise itemizing.

2. Use the subsequent code snippet to rearrange a simple ChatGPT request:

  
  chat_completion = shopper.chat.completions.create(
      model="gpt-4",
      messages=[{"role": "user", "content": "query"}]
  )
  print(chat_completion.choices[0].message.content material materials)

Proper right here, shopper.chat.completions.create is a approach title on the shopper object. The chat attribute accesses the chat-specific functionalities of the API, and completions.create is a method that requests the AI model to generate a response or completion based totally on the enter provided.

Change the query with the quick you wish to run, and be at liberty to utilize any supported GPT model as a substitute of the chosen GPT-4 above.

Coping with errors

Whereas making requests, diversified factors could occur, along with neighborhood connectivity points, price limit exceedances, or totally different non-standard response standing code. Subsequently, it’s vital to take care of these standing codes accurately. We’re ready to make use of Python’s try and apart from blocks for sustaining program circulation and better error coping with:

try:
    chat_completion = shopper.chat.completions.create(
        model="gpt-4",
        messages=[{"role": "user", "content": "query"}],
        temperature=1,
        max_tokens=150  
    )
    print(chat_completion.choices[0].message.content material materials)

apart from openai.APIConnectionError as e:
    print("The server could not be reached")
    print(e.__cause__)

apart from openai.RateLimitError as e:
    print("A 429 standing code was obtained; we should always all the time once more off a bit.")

apart from openai.APIStatusError as e:
    print("One different non-200-range standing code was obtained")
    print(e.status_code)
    print(e.response)

Phrase: it’s best to have obtainable credit score rating grants to have the power to make use of any model of the OpenAI API. If higher than three months have handed since your account creation, your free credit score rating grants have probably expired, and in addition you’ll should buy additional credit score (a minimal of $5).

Now listed below are some strategies chances are you’ll extra configure your API requests:

• Max Tokens. Prohibit the utmost potential output dimension based mostly in your desires by setting the max_tokens parameter. That is normally a cost-saving measure, nevertheless do discover that this merely cuts off the generated textual content material from going earlier the limit, not making the overall output shorter.
• Temperature. Regulate the temperature parameter to manage the randomness. (Higher values make responses additional varied, whereas lower values produce additional fixed options.)

If any parameter isn’t manually set, it makes use of the respective model’s default value, like 0 — 7 and 1 for GPT-3.5-turbo and GPT-4, respectively.

Aside from the above parameters, there are fairly a number of totally different parameters and configurations chances are you’ll make to make the most of GPT’s capabilities exactly the easiest way it’s worthwhile to. Discovering out OpenAI’s API documentation is de facto helpful for reference.
