Replace your_api_key_here with your actual OpenAI API key. You can get an API key by:
- Going to OpenAI's platform
- Creating an account or signing in
- Navigating to the API keys section
- Creating a new API key
- Make sure you have set up your

- The chatbot uses GPT-4 model for generating responses
- The system is configured to provide car showroom-specific information
The chatbot can be easily adapted for use in any field by modifying the system instructions in the OpenAIService class. The instructions are located in the content parameter of the system message in lib/services/openai_service.dart. Simply update the instructions to match your desired use case, and the chatbot will respond accordingly.
For example, to change it from a car showroom chatbot to a restaurant chatbot, you would modify the system instructions to include information about:
- Menu items and prices
- Operating hours
- Reservation policies
- Special offers
- Dietary restrictions
- And other restaurant-specific details
