## AI overview

The article describes a Reactor-AWS collaboration that uses the Neuron Kernel Interface to address dynamic shapes, memory access, and cache management for real-time autoregressive diffusion video generation on Trainium. It also discusses the latency, scheduling, networking, Kubernetes, and streaming requirements for deploying interactive AI models globally.

## Source excerpt

Using the Neuron Kernel Interface, a Reactor-AWS collaboration tackled the dynamic shapes, memory access patterns, and cache management that make real-time autoregressive diffusion hard--building techniques that generalize across models.
