Introducing Waypoint-1: Real-time interactive video diffusion from Overworld

Introduces Waypoint-1, a real-time interactive video diffusion model trained with diffusion forcing and post-trained with self-forcing. Details the WorldEngine inference library, highlighting optimizations like AdaLN feature caching, static rolling KV cache, matmul fusion, and Torch Compile for low-latency, high-throughput video generation on consumer hardware. Provides a Python code example for using WorldEngine.
