Want to build a chatbot powered by Open AI’s cutting-edge AI? This tutorial walks you through integrating Open AI’s API with Python to create a simple conversational bot.

Prerequisites

  • Python 3.8+
  • Open AI API key (sign up at Open AI’s developer portal)
  • requests library (pip install requests)

Step-by-Step Guide

  1. Set Up Your Environment: Install the required libraries and store your API key securely.
  2. Make API Calls: Use the following code to send a prompt and receive a response:
import requests

api_key = "your-api-key"
url = "https://api.openai.com/v1/chat/completions"
headers = {"Authorization": f"Bearer {api_key}", "Content-Type": "application/json"}
data = {
    "model": "gpt-4",
    "messages": [{"role": "user", "content": "Hello, how can I assist you today?"}]
}
response = requests.post(url, headers=headers, json=data)
print(response.json()["choices"][0]["message"]["content"])
  1. Build the Chatbot: Create a loop to handle user input and API responses for a conversational flow.

Tips

  • Handle rate limits by implementing retry logic.
  • Experiment with model parameters like temperature for creative responses.
