# MosaiChunk
Learned memory-router checkpoints for **MosaiChunk: Compositing Spatio-Temporal Memory for Autoregressive Video Generation**.
[Project page](https://mosaichunk.github.io/) 路 [Paper](https://arxiv.org/abs/2610.02153) 路 [Code](https://github.com/mosaichunk/MosaiChunk) 路 [RememBench](https://huggingface.co/datasets/mosaichunk/RememBench)
| Checkpoint | Backbone |
|---|---|
| [`t2v/model.safetensors`](t2v/model.safetensors) | RAVEN-adapted MiniMax-H3 (H3-AR) |
| [`i2v/model.safetensors`](i2v/model.safetensors) | LingBot-World-Infinity |
Each folder contains router weights and `config.json`. The weights are exported without changing tensor values; optimizer and training state are excluded.
These checkpoints require their corresponding frozen video backbone. T2V also requires the pretrained RAVEN streaming adapter. Backbone and adapter weights are not bundled here.
## Download
```python
from huggingface_hub import snapshot_download
snapshot_download("mosaichunk/MosaiChunk", local_dir="checkpoints/MosaiChunk")
```
See the [code repository](https://github.com/mosaichunk/MosaiChunk) for training and inference.
