Yahoo Mail turns to Vespa to do RAG at scale

Yahoo Mail, a leading global email provider, is enhancing its service with AI-driven features that allow users to interact with their inbox through questions and commands. This innovation is powered by Retrieval Augmented Generation (RAG), which combines a large language model for text understanding and generation with a retrieval system using semantic search and vector embeddings to find relevant inbox information. Vespa.ai's technology plays a crucial role in this development by providing a cost-effective RAG system capable of handling personal data, supporting vector embeddings, structured data, and full text within queries and ranking functions. This collaboration aims to offer these advanced features to all users for free, significantly simplifying and accelerating email interactions. Vespa.ai's robust vector database technology is proven to efficiently store and search trillions of documents, making it an ideal choice for Yahoo Mail's ambitious project.
