LynnReal Lightweight Video VAE

Code: LynnReal-AI/LynnReal-Omni

A complete codec with the unchanged MiniMax H3 encoder and a distilled 26-block video decoder. Latent channels, normalization, spatial scale and temporal compression match the official VAE. Deployment uses the decoder EMA parameters.

config.json and the indexed Safetensors shards follow the Diffusers component layout. decode_config.json records the release decoder settings. Load with model.light_vae.LightVAE.from_pretrained("weight/light-vae"), or pass --light-vae weight/light-vae to script/sample.py. Native decoding tiles are the default; precision and tile geometry must accompany speed/quality comparisons.

The codec changes reconstruction, not the denoiser latent interface. The same latent need not decode to identical RGB under the official and lightweight VAE. See LICENSE and the release NOTICE for MiniMax H3 terms and attribution.
