Trip Genius: Agentic Travel Automation

Trip Genius is an AI-driven agentic travel planning and booking platform that integrates flights, hotels, and itinerary management into a unified system. Using Large Language Models (LLMs) such as GPT-3.5-turbo, GPT-4o-mini and GPT-4o, the platform employs Natural Language Processing (NLP) to extract user preferences and automate end-to-end travel logistics. Unlike traditional travel systems that stop at planning, Trip Genius leverages real-time API interactions with services like Amadeus, Google Places, and TripAdvisor to enable direct bookings \cite{patil2023gorilla}. Its modular agent-based architecture comprises specialized agents for flight booking, hotel reservations, and itinerary generation, ensuring scalability and flexibility. Trip Genius introduces a novel graph-based clustering and optimization algorithm for itinerary planning and is the first solution to completely automate end-to-end travel bookings for the user. The evaluation results demonstrate a 98.7\% entity extraction accuracy, 100\% intent matching accuracy, and a TP99 latency of 4.85 s, highlighting the reliability and efficiency of the system. By providing a seamless, automated, and personalized travel experience, Trip Genius reduces manual effort and sets a new standard in AI-driven travel solutions.
