Research on AI – Powered Medical Chat - Bot Using Rag

The use of artificial intelligence (AI) in medicine has created medical Chat - bots that supports real -time patients, symptom assessment, early diagnosis and supportive patient training. However, traditional Chat -bot models based on static database or pre-influensing reactions have problems with chronic information,reference upheaval and the possibility of incorrect information. Recovery-sized generation (RAG) is asophisticated AI model that supports the chat bot capacity by integrating a recovery system with generative AI,and ensures that reactions are relevant sounds and most infected with today's medical knowledge. This articleemphasizes the main elements of the theoretical base and the real application of Raga-based medical chat bots thatenable better accuracy, flexibility and user interactions. We discuss architecture, recycling process and responsegeneration mechanisms that distinguish rag from traditional NLP - based chat-bots. In addition, we explain indetail about the significant strength of Rag, such as medical accuracy, real -time flexibility and adapted patientinteraction. While the possibilities are very good, the implementation of carpet -based medical chat-bots isaccompanied by computational overhead, data security and difficulties with regulatory requirements. We discussthese boundaries in adding possible solutions to make chat bot more reliable and effective. Case studies of realimplementation also give us a picture of how effective they are and practically how they are used in modern healthcare. Finally, we identify future research directions by integrating RAG-based medical chat bot with newtechniques such as IOT, Block chain and Multi-model AI to further change the digital health service. Byaddressing these main areas, this research tries to contribute to continuous progress of AI-driven medical chat bot,so that they can become an integral part of both health care professionals and patients.
