How to find and Use API Key of OpenAI

OpenAI provides its API to interact with their language models. To make use of these models, you need to have an API key which serves as your authentication method. This key enables your application to securely communicate with OpenAI’s servers and access their services.

Project with OpenAI API Key

Lets see an example to understand the working and integration of OpenAI API key in projects and applications.

Step 1: Install Required Libraries

To interact with the OpenAI API in Python, we need to install the OpenAI library.

pip install openai

Step 2: Setting Up Your API Key

The openai.api_key is where you input your personal API key. It’s crucial for authenticating and making requests to OpenAI's API.

import openai

openai.api_key = 'your-api-key-here'

Step 3: Create the Chatbot Function

• The openai.Completion.create function sends the user input to the GPT model which generates a response.
• The temperature parameter controls the creativity of the output.

def chatbot_conversation():
    print("Hello! I'm your Personal chatbot. Type 'exit' to end the conversation.")

    while True:
        user_input = input("You: ")

        if user_input.lower() == 'exit':
            print("Goodbye!")
            break

        response = openai.Completion.create(
            engine="text-davinci-003",
            prompt=user_input,
            max_tokens=150,
            temperature=0.7
        )

        chatbot_response = response.choices[0].text.strip()

        print("Chatbot: " + chatbot_response)

Step 4: Running the Chatbot

if __name__ == "__main__":
    chatbot_conversation()
