+
+Uni-3DAR is an autoregressive model that unifies various 3D tasks. In particular, it offers the following improvements:
+
+1. **Unified Handling of Multiple 3D Data Types.**  
+   Although we currently focus on microscopic structures such as molecules, proteins, and crystals, the proposed method can be seamlessly applied to macroscopic 3D structures.
+
+2. **Support for Diverse Tasks.**  
+   Uni-3DAR naturally supports a wide range of tasks within a single model, especially for both generation and understanding.
+
+3. **High Efficiency.**  
+   It uses octree compression-in combination with our proposed 2-level subtree compression-to represent the full 3D space using only hundreds of tokens, compared with tens of thousands in a full-size grid. Our inference benchmarks also show that Uni-3DAR is much faster than diffusion-based models.
+
+4. **High Accuracy.**  
+   Building on octree compression, Uni-3DAR further tokenizes fine-grained 3D patches to maintain structural details, achieving substantially better generation quality than previous diffusion-based models.
