800M Causal Diffusion Model Runs Playable Characters on Consumer GPUs

An 800M parameter video diffusion model using causal diffusion with KV-cache frame storage converts images into controllable playable characters, running at 60+ fps on an RTX 5090 for the 500M variant. The architecture extends standard diffusion denoising by appending each generated frame to a KV cache, enabling temporal context across 12 latent frames; consistency issues remain but flash artifacts from the prior version are resolved.
