KDDI Optimizes RAG Performance with ADK
📘 KDDI developed Buffmee, a consumer-facing Retrieval-Augmented Generation (RAG) app, to provide grounded, trustworthy AI-assisted learning across books, magazines, and web media. Facing latency and hallucination challenges, KDDI worked with KDDI iret and Google Cloud teams to implement automated evaluation using Gemini Enterprise, BigQuery Agent Analytics, and the Agent Development Kit (ADK). These optimizations reduced response latency by 38% and improved TTFT by nearly 18%, while boosting groundedness by 25% through systematic testing and prompt modularization. The result is a faster, more reliable experience that preserves content trust and compliance.
