# WNM-3D

WNM-3D is a generative world navigation model for continuous
vision-language navigation. It converts monocular egocentric RGB history into
persistent geometry-aware scene tokens and jointly generates future views and
navigation actions for closed-loop control.

> **License notice:** The released checkpoints embed VGGT-Ω/DINOv3-derived
> parameters. Use and redistribution are subject to the FAIR Noncommercial
> Research License, the DINOv3 License, and other applicable third-party terms.

- [Paper](https://arxiv.org/abs/2608.07267)
- [Source code and documentation](https://github.com/TeleHuman/WNM-3D)

- [GN-Matrix dataset](https://huggingface.co/datasets/TeleEmbodied/GN-Matrix)

## Released Checkpoints

| Directory | Training stage | Recommended use |
| --- | --- | --- |
| `wnm_3d_stage1_release` | Offline A\* SFT | Stage-I analysis and initialization |
| `wnm_3d_stage2_release` | Closed-loop DAgger-SFT | Stage-II analysis and initialization |
| `wnm_3d_stage3_release` | Counterfactual DanceGRPO | Evaluation and inference |

The Stage-III checkpoint is the primary released policy. Each directory is a
self-contained inference checkpoint; standalone Wan, UMT5-XXL, and VGGT-Ω
initialization weights are not required for evaluation.

## Download

```bash
hf download TeleEmbodied/WNM-3D \
  --include "wnm_3d_stage3_release/**" \
  --local-dir checkpoints
```

## Inference

Install WNM-3D by following the
[installation guide](https://github.com/TeleHuman/WNM-3D/blob/main/docs/INSTALLATION.md),
then launch a single policy replica:

```bash
bash scripts/inference/wnm_3d_server.sh \
  --model-path checkpoints/wnm_3d_stage3_release \
  --cuda-devices 0 \
  --num-replicas 1 \
  --base-port 8000
```

Run the GN-Bench client from a sibling GN0 checkout:

```bash
cd ../GN0
bash scripts/evaluation/eval_remote.sh \
  --exp-config configs/gn_bench/interiorgs/test_unseen.yaml \
  --enable-stall-recovery \
  --num-gpus 1 \
  --result-dir tmp/eval/wnm_3d_test_unseen
```

The reference single-replica deployment was validated on an NVIDIA H100 80 GB
GPU and used approximately 27 GiB of GPU memory after loading. A released
checkpoint occupies approximately 26 GiB. These figures are observations from
the reference configuration, not strict minimum requirements.

## Intended Use and Limitations

WNM-3D is intended for research on embodied navigation, world models, and
closed-loop vision-language navigation. The released policy was developed and
evaluated with the InteriorGS scenes and GN-Matrix task annotations used by
GN-Bench. Performance may not transfer to new simulators, sensors, scene
distributions, languages, or physical robots without additional validation.

Generated actions can fail or behave unexpectedly. Do not use the model as a
safety-critical controller or deploy it around people, property, or physical
systems without appropriate safeguards and human oversight.
