# 1X World Model Compression Challenge Dataset
This repository hosts the dataset for the [1X World Model Compression Challenge](https://huggingface.co/spaces/1x-technologies/1X_World_Model_Challenge_Compression).

```bash
huggingface-cli download 1x-technologies/worldmodel --repo-type dataset --local-dir data
```

## Updates Since v1.1

- **Train/Val v2.0 (~100 hours)**, replacing v1.1
- **Test v2.0 dataset for the Compression Challenge**
- **Faces blurred** for privacy
- **New raw video dataset** (CC-BY-NC-SA 4.0) at [worldmodel_raw_data](https://huggingface.co/datasets/1x-technologies/worldmodel_raw_data)
- **Example scripts** now split into:
  - `cosmos_video_decoder.py` — for decoding Cosmos Tokenized bins
  - `unpack_data_test.py` — for reading the new test set
  - `unpack_data_train_val.py` — for reading the train/val sets

---

## Train & Val v2.0

### Format

Each split is sharded:  
- `video_{shard}.bin` — [NVIDIA Cosmos Tokenizer](https://github.com/NVIDIA/Cosmos-Tokenizer) discrete DV8×8×8 tokens at 30 Hz  
- `segment_idx_{shard}.bin` — segment boundaries  
- `states_{shard}.bin` — `np.float32` states (see below)  
- `metadata.json` / `metadata_{shard}.json` — overall vs. per‐shard metadata


---

## Test v2.0

We provide a 450 sample **test_v2.0** dataset for the [World Model Compression Challenge](https://huggingface.co/spaces/1x-technologies/1X_World_Model_Challenge_Compression) with a similar structure (`video_{shard}.bin`, `states_{shard}.bin`). Use:
- `unpack_data_test.py` to read the test set
- `unpack_data_train_val.py` to read train/val

## Previous v1.1

- `video.bin` — 16×16 patches at 30Hz, quantized
- `segment_ids.bin` — segment boundaries
- `actions/` folder storing multiple `.bin`s for states, closures, etc.

A separate `val_v1.1` set is available.

## Provided Checkpoints

- `magvit2.ckpt` from [MAGVIT2](https://github.com/TencentARC/Open-MAGVIT2) used in v1.1
- For v2.0, see [NVIDIA Cosmos Tokenizer](https://github.com/NVIDIA/Cosmos-Tokenizer); we supply `cosmos_video_decoder.py`.
