Custom Chatbot with OpenAI (ChatGPT)

Welcome to the Custom Chatbot with OpenAI project! This project aims to guide you through the process of building a custom chatbot using OpenAI's language model. The chatbot is designed to interact with users and provide relevant responses based on a knowledge base.

Getting Started

To get started with the project, follow the steps below:

1. Clone the project repository to your local machine.
2. Install the required dependencies by running the following command: pip install -r requirements.txt.

Setting Up OpenAI API

To use the chatbot, you need to obtain an API key from OpenAI. Follow the instructions below to set up the API:

1. Sign up for an account on the OpenAI website.
2. Once you have an account, obtain your API key.
3. Set the API key in the appropriate code file app.py by replacing 'Add your API Key here' with your actual API key.

Building the Chatbot

The chatbot is built in two main steps: creating a knowledge base and implementing the chatbot class. Follow the instructions below:

Creating a Knowledge Base

1. Prepare a collection of documents or data that will serve as the knowledge base for the chatbot. The documents should be in a format that can be indexed and searched.
2. Use the GPTVectorStoreIndex class from the Llamas library to create an index for the documents. This will enable efficient retrieval of information.
3. Save the index to a persistent storage directory.

Implementing the Chatbot Class

1. Use the Chatbot class provided in the code to implement the chatbot functionality.
2. Set the API key, index, and other necessary parameters in the Chatbot class constructor.
3. Use the generate_response method to generate responses based on user input.
4. Customize the chatbot's behavior and responses by fine-tuning the prompts and training data.

Running the Chatbot

To run the chatbot, execute the following steps:

1. Ensure that you have set up the API key and other configurations in the appropriate code file.
2. Run the streamlit run app.py in your terminal, Access the application through the provided URL.

Conclusion

Congratulations! You have successfully set up and implemented a custom chatbot with OpenAI. Feel free to customize and enhance the chatbot's functionality based on your specific requirements. Enjoy exploring the possibilities of conversational AI with OpenAI's powerful language model.
