# ChatGPT Usage Example

This repository contains an example of how to use OpenAI's GPT-3.5-turbo model for interactive text-based conversations. In this example, you'll learn how to use both the OpenAI Python Package and the API Endpoint to engage in a conversation with the language model.

## Installation

You'll need to install the OpenAI Python package to use the GPT-3.5-turbo model. You can do this using the following command:

```bash
pip install -q openai

Usage

Method 1 - Using OpenAI Python Package

import openai

# Set your OpenAI API key
openai.api_key = 'your-api-key'

# Initialize the conversation with a system message
messages = [
    {"role": "system", "content": "You are a kind helpful assistant."},
]

while True:
    message = input("User : ")
    if message:
        messages.append(
            {"role": "user", "content": message},
        )
        chat = openai.ChatCompletion.create(
            model="gpt-3.5-turbo", messages=messages
        )
    
        reply = chat.choices[0].message.content
        print(f"ChatGPT: {reply}")
        messages.append({"role": "assistant", "content": reply})

Example conversation:

User : What is your name?
ChatGPT: I am a language model developed by OpenAI, and I don't have a specific name. You can call me OpenAI if you'd like. How can I assist you further?
User : Can you call me Shivansh?
ChatGPT: Sure, Shivansh. Is there anything else I can help you with?
User : What is my name?
ChatGPT: Your name is Shivansh.

Method 2 - Using API Endpoint

import requests

# Set your OpenAI API key
api_key = 'your-api-key'

URL = "https://api.openai.com/v1/chat/completions"

payload = {
    "model": "gpt-3.5-turbo",
    "messages": [{"role": "user", "content": f"What is the first computer in the world?"}],
    "temperature": 1.0,
    "top_p": 1.0,
    "n": 1,
    "stream": False,
    "presence_penalty": 0,
    "frequency_penalty": 0,
}

headers = {
    "Content-Type": "application/json",
    "Authorization": f"Bearer {api_key}"
}

response = requests.post(URL, headers=headers, json=payload, stream=False)
result = response.json()
assistant_reply = result["choices"][0]["message"]["content"]
print(f"Assistant's reply: {assistant_reply}")

Example response:

Assistant's reply: The first computer in the world was the Electronic Numerical Integrator and Computer (ENIAC), created in 1945 at the University of Pennsylvania.
