This is a Flask-based web application that uses the OpenAI GPT-3.5 model to generate custom travel itineraries based on user preferences.

1. Clone the repository:

``` git clone https://github.com/yourusername/travel-itinerary-generator.git cd travel-itinerary-generator ```

2. Set up a Python virtual environment and install the required dependencies:

```bash make env ```

3. Create an environment variable for your OpenAI API key:

```bash export OPENAI_API_KEY=your-openai-api-key ```

Replace your-openai-api-key with your actual OpenAI API key.

1. Activate the virtual environment:

```bash source venv/bin/activate ```

2. Run the Flask application from the repository root:

```bash python app/main.py ```

The Flask server will start, and you can access the application at http://localhost:5000.

3. To generate a travel itinerary, navigate to http://localhost:5000 in your web browser. Enter your travel preferences in the form and click the "Generate Itinerary" button. The generated itinerary will be displayed on the page.

4. To stop the Flask application, press Ctrl+C in the terminal.

5. To deactivate the virtual environment:

```bash deactivate ```

6. To clean up the environment (deactivate and delete the virtual environment):

```bash make clean ```

This application uses the OpenAI GPT-3.5 model to generate custom travel itineraries. The user's preferences are used to generate a prompt, which is passed to the GPT-3.5 model via the OpenAI API. The model generates a response, which is parsed and displayed as the custom travel itinerary.

This project is a demonstration of how OpenAI's powerful GPT-3.5 model can be used to create practical applications. The generated itineraries are for demonstration purposes and may not be entirely accurate or realistic.
