Wan2.1-T2V-1.3B-PhyPO (merged single model)
A single merged PhyPO-tuned Wan2.1-T2V-1.3B diffusion transformer — unlike the
per-prompt adapter collections, this is one set of weights. It is the backbone the
FastWAM *_1p3b_phypo world-model runs train from.

The VAE and T5 text encoder are not included — take them from the base repo
Wan-AI/Wan2.1-T2V-1.3B (Wan2.1_VAE.pth, models_t5_umt5-xxl-enc-bf16.pth);
locally those were symlinks into the base checkout.
