neoAI and Hankyu Railway Launch Generative AI Chatbot for 1.64M Passengers

neoAI Inc. and Hankyu Railway Co., Ltd. have co-developed and launched a generative AI chatbot for railway customer service, catering to approximately 1.64 million daily users. Unlike traditional FAQ bots, this system leverages LLM reasoning and RAG (Retrieval-Augmented Generation) to handle complex and diverse questions with flexibility. The project incorporated insights from neoAI's 'J-RAGBench' benchmark to ensure response quality. It features a guardrail design to prevent incorrect information and a structured data processing system that eliminates the need for manual FAQ updates. The deployment uses the 'neoAI Chat' platform, allowing for continuous updates to the latest AI models.
