TL;DR - LiveAnimate is a 14B-parameter video diffusion system for stable, real-time, pose-driven human animation from a single reference image. It enables long-running interactive applications while keeping memory and latency constant.

Converts a bidirectional DiT into a block-causal generator, then distills sampling to three steps.
Uses Pose-Retrieval Sink Attention and a bounded KV cache to preserve appearance over long streams.
Achieves 19.63 FPS on two NVIDIA H100 GPUs using sequence parallelism and operator fusion.
Maintains nearly constant identity and perceptual quality across a three-minute benchmark.
