The AI Institute

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, which also includes experiments demonstrating that Theia outperforms its teacher models and prior robot learning models using less training data and smaller model sizes. Demo videos can be found on the project page.

Model Details

The theia-base-patch16-224-cdiv model, uses DeiT-Base as a backbone, and simulatenously distills CLIP, DINOv2, and ViT. For more information on usage, please visit the Theia repository.
