StreamRender-H3

Part of NVIDIA's Sol-Engine work, after SoL-Refiner (week 41). A three.js racing game handles maps, physics and rules and streams a 13-class semantic map to a diffusion renderer built on MiniMax-H3 Ref2VA, which turns it into photorealistic video, with a reference image and prompt setting the look so one engine stream can be restyled. Training moves through teacher forcing, Resampling Forcing and distribution-matching distillation down to two denoising steps per chunk. Render time is 218 ms per streaming step on 8 GB200s, down from 799.7 ms, and a fast causal VAE decodes two latent frames at 720p in 23.8 ms. Code is in NVlabs/Sana; no end-to-end frame rate is stated.
