Kuaishou has unveiled OneRec, a groundbreaking end-to-end generative recommendation system. Leveraging large model technology, OneRec significantly optimizes the conventional recommendation architecture, boosting computational capacity tenfold. With computing power utilization rates soaring to 23.7% and 28.8%, and operational costs slashed to just 10.6% of traditional methods, OneRec has been seamlessly integrated into both the Kuaishou App and its Lite version. Handling 25% of QPS (Queries Per Second), the system has notably enhanced user dwell time and lifecycle, heralding a new epoch in recommendation systems.
