# LoGo checkpoints

The LoRA adapter each model was post-trained to with the LoGo reward.

| file | model | base weights |
|---|---|---|
| `logo-lyra2-lora.pt` | Lyra-2 (use DMD scheduler) | `nvidia/Lyra-2.0` |
| `logo-lingbot-world-v2-lora.pt` | LingBot-World 2.0 | `robbyant/lingbot-world-v2-14b-causal-fast` |
| `logo-uniworld-view-lora.safetensors` | UniWorld-View | `Drexubery/UniView` + `Wan-AI/Wan2.1-VACE-14B-diffusers` + CausVid LoRA |

Usage, with the code at https://github.com/ziqi-ma/logo.

    # Lyra-2
    torchrun --standalone --nproc_per_node=8 -m lyra_2._src.rl.inference.evaluate \
      --adapter logo-lyra2-lora.pt --scenes-root <scene dir> --scenes "<ids>"

    # LingBot-World 2.0
    python -m wan.rl.inference.gen_scenes --input_base <scene root> --videos_base <out> \
      --lora_path logo-lingbot-world-v2-lora.pt

    # UniWorld-View
    python -m rl.inference.eval_gen --ws_prefix <out> \
      --rl-ckpt logo-uniworld-view-lora.safetensors --pose-scale 1.5

Evaluation on TrajectoryBench, including the per-group generation settings, is described in
`eval/README.md` in that repository.
