OpenAI Chatbot

This project is a simple command-line chatbot application built using OpenAI's API, specifically using the chatgpt.py script. The chatbot is designed to handle natural language conversations, providing useful, contextually relevant responses to user inputs.

Features

• Interactive command-line interface.
• Powered by OpenAI's gpt-3.5-turbo model by default.
• Easy setup using an environment file for your API key.
• Easily customizable to use other OpenAI chat models.

Prerequisites

• Python 3.x
• An API key from OpenAI.

Getting Started

Follow these steps to get the chatbot running on your local machine.

1. Clone the Repository

Clone this repository to your local machine. If you don't have a repository URL, you can just download the files.

# Example of cloning a repository
git clone <repository-url>
cd openai-chatbot

2. Install Dependencies

The script requires the openai and python-dotenv libraries. It's recommended to use a virtual environment. You can install them using the requirements.txt file.

# Install the required packages
pip install -r requirements.txt

3. Configure API Key

The application loads your OpenAI API key from a .env file for security.

1. In the project's root directory (the same directory as chatgpt.py), create a file named .env.

2. Add the following line to the .env file, replacing your-openai-api-key with your actual secret key:

   OPENAI_API_KEY='your-openai-api-key'

Usage

To run the chatbot, execute the chatgpt.py script from your terminal:

python chatgpt

You can now start a conversation in your terminal. To end the session, type exit and press Enter.

Customization

Changing the AI Model

By default, the chatbot uses the gpt-3.5-turbo model. You can easily switch to another model available to your account (e.g., gpt-4, gpt-4-turbo) by editing the chatgpt.py file.

Locate the chatbot function and change the value of the model parameter in the client.chat.completions.create call.
