The upstream root README states Apache License 2.0. An additional model card at
this same snapshot names the NVIDIA Internal Scientific Research and Development

DiTGS retains and fine-tunes the latent-velocity transformer; FlashWorld's
Gaussian-feature output channels and reconstruction decoder are not distributed.

Revision: b8fff7315c768468a5333511427288870b2e9635 (Apache-2.0).

Changes: camera-corrected multiview preprocessing/conditioning, feature adapter,
independent DiT-memory attention and KV projections, per-channel residual scaling,
and fine-tuning the Wan backbone and TokenGS Gaussian decoder/head with the
10,000-update warmup plus 20,000-update joint DiTGS schedule.

The pretrained Wan VAE and TokenGS image encoder are retained frozen.
No optimizer, EMA, RNG state, dataset images or external text encoder is included.
