How avatarin built a 24/7 retail agent with GPT-Realtime

avatarin, an AI customer service company, built a 24/7 multilingual shopping agent for Yamada Denki using OpenAI's GPT-Realtime (a real-time AI model that handles voice, text, and images together). The agent uses RAG (retrieval-augmented generation, where the AI pulls in external product information to answer questions) to give shoppers expert advice on products like refrigerators by understanding context and asking follow-up questions, rather than just waiting for keywords like a traditional chatbot.
