VideoVAE+ vs Cosmos — Latent tokenizer diagnostic for visuo-tactile world model Timeline: 2026-07-02 to 2026-07-03. Diagnosing whether our current VideoVAE+ latent tokenizer has architectural issues that hurt downstream world model training, and whether NVIDIA's Cosmos Tokenizer CV4x8x8 is a viable replacement. TL;DR Two architectural issues found in VideoVAE+, both absent in Cosmos: Right-bottom spatial hotspot — Downsample2plus1D uses asymmetric zero-pad on… See the full description on the dataset page: https://huggingface.co/datasets/yxma/vtwm-tactile-latent-delta-viz.
