OpenTable has revolutionized its restaurant discovery process by introducing Concierge, an AI-powered dining assistant that leverages Qdrant for efficient data management. Recognizing the shift towards conversational and intelligent search tools due to the rise of generative AI, OpenTable aimed to transform how diners find restaurants. Concierge, developed with a focus on accuracy, domain-centric responses, and speed, relies on Qdrant for its ability to handle sparse embeddings and provide high-precision filtering, which is crucial for narrowing down results from over 60,000 restaurants. The deployment of Qdrant Cloud simplified the process, ensuring stable, global operations from the outset. This new system not only enhances user experience but also serves as a testbed for refining OpenTable's AI and retrieval infrastructure, setting the stage for future innovations like conversational search and visual dish discovery, while maintaining operational stability and allowing the team to concentrate on model performance improvements.
