# Model Card for Hume-System2


<!-- Provide a quick summary of what the model is/does. -->
System 2 pretrianed weights of a Dual-System Visual-Language-Action model for accelerating training of System 2.
- Paper: [https://arxiv.org/abs/2505.21432](https://arxiv.org/abs/2505.21432)
- Homepage: [https://hume-vla.github.io](https://hume-vla.github.io)
- Codebase: [🦾 Hume: A Dual-System VLA with System2 Thinking](https://github.com/hume-vla/hume) ![GitHub Repo stars](https://img.shields.io/github/stars/hume-vla/hume)


## Uses

<!-- Address questions around how the model is intended to be used, including the foreseeable users of the model and those affected by the model. -->
- Download the weights
- Set `pretrained_policy` to the path to weights in [scripts/train_s2.sh](https://github.com/hume-vla/hume/blob/main/scripts/train_s2.sh#L54)
- Launch training `bash scripts/train_s2.sh`

## Citation

<!-- If there is a paper or blog post introducing the model, the APA and Bibtex information for that should go in this section. -->
