Before embarking on your journey with GPT-3, make sure you have completed the following prerequisites:

1. Sign up for an OpenAI account

Visit and sign up for an account. This step is crucial for accessing the GPT Store and obtaining an API key.

2. Get an API key

Navigate to your account page on the OpenAI platform and acquire your API key. This key will serve as the gateway to unlocking GPT-3’s potential in your applications.

3. Install the OpenAI Python package

Ensure that you have the OpenAI Python package installed in your development environment. You can easily install it using the following command:

pythonCopy code

pip install openai = YOUR_API_KEY”


Once you have your API key and the OpenAI package installed, set up your Python environment for GPT-3 integration:

pythonCopy code

import openai openai.api_key = “YOUR_API_KEY”

Replace “YOUR_API_KEY” with the actual API key you obtained from your OpenAI account.


GPT-3 offers several models or engines, each with varying levels of capability. These engines include:

  • ada
  • babbage
  • curie
  • davinci

Choose the engine that aligns with your specific requirements. For instance, if you need advanced language understanding and generation, “davinci” is a great choice.

To set the engine in your Python script, use the following code snippet:

pythonCopy code

engine = “davinci”

Feel free to experiment with different engines based on your project’s needs.

Completion Endpoint

The completion endpoint is where the magic happens. It allows you to provide a prompt and receive GPT-3’s completion. Use the following Python code to make a completion request:

pythonCopy code

response = openai.Completion.create( engine=engine, prompt=”Hello”, max_tokens=5 ) print(response[“choices”][0][“text”])

Adjust parameters like max_tokens and temperature to control the length and creativity of the response. Experiment with these values to achieve the desired output for your application.


One of the unique features of GPT-3 is its adaptability to specific domains and tasks through fine-tuning. This is particularly useful for models like “curie” and “davinci.” To fine-tune a model, provide training examples in a JSONL file and use the following code:

pythonCopy code

fine_tune_response = openai.FineTunes.create( training_file=”file.jsonl”, model=engine )

Fine-tuning allows GPT-3 to learn and adapt to your specific requirements, enhancing its performance in specialized domains.

Table: GPT-3 Engines Comparison

adaA capable engine suitable for various tasks
babbageIntermediate model for diverse applications
curieIdeal for fine-tuning and task adaptation
davinciAdvanced engine with superior language capabilities

Experiment with different engines to find the one that best fits your project’s objectives.


OpenAI’s GPT-3, coupled with the GPT Store, provides developers with a potent tool for natural language processing and generation. By following this tutorial, you’ve gained insights into setting up your environment, choosing engines, utilizing the completion endpoint, and fine-tuning models.

As you embark on your journey with GPT-3, don’t hesitate to explore and experiment. The possibilities are vast, and with the right configurations, you can unlock the full potential of GPT-3 for your specific applications. If you have any questions along the way, feel free to reach out and leverage the OpenAI community for support.

Now, armed with the knowledge and tools provided in this tutorial, you’re ready to integrate GPT-3 into your projects and witness the transformative impact of advanced language models. Happy coding!
