OpenAI GPT-3: How to Setup Easily NOW

OpenAI GPT-3

This article assumes you have already created an account with OpenAI. Once you have done that you should be able to create your API key. You will need this API key to start doing the really cool things that OpenAI GPT-3 is capable of. I would suggest starting with some simple NLP projects. This quick setup will allow you to start using GPT-3 with Python.

GPT-3 (Generative Pre-trained Transformer 3) is a state-of-the-art AI language model developed by OpenAI. It is designed to generate natural language text that is almost indistinguishable from human writing. GPT-3 has numerous use cases across various industries, including:

Natural Language Generation (NLG)

GPT-3 can be used for NLG tasks such as article writing, social media content creation, and email responses. It can generate text that is grammatically correct, coherent, and tailored to specific audiences.

Chatbots and Conversational AI

GPT-3 can be used to create chatbots and conversational AI systems that can understand natural language input and respond with human-like text. It can improve customer service, enhance user experience, and streamline business operations.

Language Translation and Summarization

GPT-3 can be used for language translation and summarization tasks. It can accurately translate text from one language to another and summarize lengthy articles or documents, saving time and resources.


First, I will create an ‘.env’ file in our project directory, where I will store my OpenAI API Key.


Now I’ll open up my favorite IDE at the moment, VSCode, and start. To make things a bit more mainstream, let us create a Python Class for working with OpenAI GPT-3.

import openai
class GPT3:
    def __init__(self, api_key):
        openai.api_key = api_key
        self.engine = "text-davinci-003"
    def set_engine(self, engine):
        self.engine = engine
    def generate_text(self, prompt, max_tokens=50, temperature=0.5):
        openai.api_key = self.api_key
        response = openai.Completion.create(
        return response.choices[0].text.strip()

In the above example, we define a “GPT3” class that takes an “api_key” parameter as its constructor argument. The “api_key” is used to authenticate with the OpenAI API.

The “set_engine()” method can be used to change the engine being used. By default, the “text-davinci-003” engine is used.

Finally, the “generate_text()” method takes a prompt parameter, which is the text to generate from. Other parameters like “max_tokens” and “temperature” can also be passed to control the generated text’s length and randomness, respectively.

Note that this is just a simple example of a GPT-3 class structure. And the actual implementation may vary depending on the specific use case and requirements. GPT-3 has a wide range of applications, and its potential is still being explored by developers and businesses. It is a powerful tool for generating high-quality content and improving the efficiency of various language-related tasks.
