Google releases AsyncRetrieveContexts and AskContexts APIs for RAG Cross Corpus Retrieval
Action Required
Applications relying on RAG will require code updates to leverage the new multi-corpus retrieval capabilities, potentially impacting existing workflows and requiring development effort.
AI Impact Summary
Google is releasing a new capability, AsyncRetrieveContexts and AskContexts APIs, that allows users to retrieve relevant contexts from multiple RAG corpora simultaneously. This enables a more sophisticated approach to RAG (Retrieval-Augmented Generation) by allowing models to draw information from diverse sources, potentially improving answer quality and reducing hallucinations. This change requires developers to update their applications to utilize these new APIs.
