1X World Model Compression Challenge Dataset

This repository hosts the dataset for the 1X World Model Compression Challenge.

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
• 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 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 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

• segment_ids.bin — segment boundaries
• actions/ folder storing multiple .bins for states, closures, etc.

## 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`.
