# GPTClone
GPTClone is a FastAPI-based chat application that uses langchain for conversation memory and OpenAI's language models to provide intelligent responses.
## Features
- FastAPI backend for efficient API handling
- Langchain integration for improved conversation memory
- OpenAI's GPT model for generating responses
- In-memory chat history storage
- Markdown formatting for better response presentation
## Prerequisites
- Python 3.7+
- OpenAI API key
## Installation
1. Clone the repository:
```
git clone https://github.com/marketcalls/gptclone.git
cd gptclone
```
2. Create a virtual environment and activate it:
```
python -m venv venv
source venv/bin/activate # On Windows, use `venv\Scripts\activate`
```
3. Install the required packages:
```
pip install -r requirements.txt
```
4. Create a `.env` file in the project root:
```
cp .sample.env .env
```
Then, edit the `.env` file and replace the placeholder values with your actual OpenAI API key and desired model:
```
OPENAI_API_KEY=your_api_key_here
OPENAI_MODEL=gpt-4o-mini
```
## Usage
1. Start the FastAPI server:
```
uvicorn app.main:app --reload
```
2. Open a web browser and navigate to `http://localhost:8000` to use the chat interface.
