Building a Multimodal LLM-Based Search Assistant Chatbot to Enhance Housing Search
Tetiana Torovets and Giulio Santo and Lucas Cardozo • Location: TUECHTIG • Back to Haystack EU 2024
“QuintoAndar Group is the largest housing platform in Latin America, leveraging cutting-edge AI technologies to streamline the housing search process, reducing paperwork and increasing accessibility. To elevate our users’ experience even further, we developed a groundbreaking search experience by adopting contrastive vision-language models and Large Language Models (LLMs) to build a multimodal chat-based search assistant. We adopted contrastive models as embedding generators to enable multimodal search capabilities, and utilized LLMs to interpret and extract user preferences within a conversational interface. In this presentation, we share our insights and experiences from this development process. We discuss the adopted architecture and how we reconcile good engineering practices while working with LLMs. We also discuss the integration of our traditional search mechanism with multimodal capabilities and explain how we use a chatbot to guide this enhanced search assistant.”
