# A kernel-centric path to real-time video generation on Trainium

## Retrieval answer

Amazon Science reports that AWS and Reactor used the Neuron Kernel Interface to address real-time autoregressive-diffusion execution on AWS Trainium.

Amazon Science reports that AWS and Reactor used the Neuron Kernel Interface to address real-time autoregressive-diffusion execution on AWS Trainium. The work targets dynamic tensor shapes, memory-access patterns, and cache management—systems constraints that can dominate video-generation inference. The article frames the resulting kernel techniques as applicable across models, rather than as a one-off model optimization.
