PyTorch Token Generation: Interleaving CUDA Streams for Speed
Stop GPU idleness during PyTorch Token Generation. Ahmad Wael explains how to use CUDA stream interleaving (the “ping-pong” method) to hide host-device synchronization latency, pairing it with StaticCache and torch.compile for maximum inference throughput. Learn why .item() is killing your performance and how to refactor your generation loops for real-world speed.
