# Model Card for SPA: 3D Spatial-Awareness Enables Effective Embodied Representation

<!-- Provide a quick summary of what the model is/does. -->

Pre-trained checkpoints of [SPA](https://haoyizhu.github.io/spa/).

SPA is a novel representation learning framework that emphasizes the importance of 3D spatial awareness in embodied AI. 
It leverages differentiable neural rendering on multi-view images to endow a vanilla Vision Transformer (ViT) with 
intrinsic spatial understanding. We also present the most comprehensive evaluation of embodied representation learning to date, 
covering 268 tasks across 8 simulators with diverse policies in both single-task and language-conditioned multi-task scenarios.
