# Theia

[The AI Institute](https://theaiinstitute.com/)

Theia is a vision foundation model for robot learning that distills multiple off-the-shelf vision foundation models trained on varied vision tasks. Theia’s rich visual representations encode diverse visual knowledge, enhancing downstream robot learning. It was introduced in the paper [Theia: Distilling Diverse Vision Foundation Models for Robot Learning](https://arxiv.org/abs/2407.20179), which also includes experiments demonstrating that Theia outperforms its teacher
models and prior robot learning models using less training data and smaller model sizes.

## Model Details

The `theia-small-patch16-224-cdiv` model, uses [DeiT-Small](https://huggingface.co/facebook/deit-small-patch16-224) as a backbone, and simulatenously distills [CLIP](https://github.com/openai/CLIP), [DINOv2](https://github.com/facebookresearch/dinov2), and [ViT](https://github.com/google-research/vision_transformer). For more information on usage, please visit the [Theia repository](https://github.com/bdaiinstitute/theia/tree/main).
