LitePT embodies the simple principle "convolutions for low-level geometry, attention for high-level relations" and strategically places only the required operations at each hierarchy level. LitePT is equipped with a novel, parameter-free 3D positional encoding, PointROPE. The resulting model achieves state-of-the-art performance while being significantly more efficient. ## Paper & Resources - **Paper:** [LitePT: Lighter Yet Stronger Point Transformer](https://huggingface.co/papers/2512.13689) - **Arxiv:** [https://arxiv.org/abs/2512.13689](https://arxiv.org/abs/2512.13689) - **Project Page:** [https://litept.github.io/](https://litept.github.io/) - **Codebase:** [https://github.com/prs-eth/LitePT](https://github.com/prs-eth/LitePT) ## Models We release the pretrained model weights for the benchmarks we reported in our paper. ### Semantic segmentation | Model | Params | Benchmark | val mIoU | Config | Checkpoint | |:-|-:|:-:|:-:|:-:|:-:| | LitePT-S | 12.7M | NuScenes | 82.2 | [link](https://github.com/prs-eth/LitePT/blob/main/configs/nuscenes/semseg-litept-small-v1m1.py) | [Download](https://huggingface.co/yuanwenyue/LitePT/blob/main/nuscenes-semseg-litept-small-v1m1/model/model_best.pth) | | LitePT-S | 12.7M | Waymo | 73.1 |[link](https://github.com/prs-eth/LitePT/blob/main/configs/waymo/semseg-litept-small-v1m1.py) | [Download](https://huggingface.co/yuanwenyue/LitePT/blob/main/waymo-semseg-litept-small-v1m1/model/model_best.pth) | | LitePT-S | 12.7M | ScanNet | 76.5 |[link](https://github.com/prs-eth/LitePT/blob/main/configs/scannet/semseg-litept-small-v1m1.py) | [Download](https://huggingface.co/yuanwenyue/LitePT/blob/main/scannet-semseg-litept-small-v1m1/model/model_best.pth) | | LitePT-S | 12.7M | Structured3D | 83.6 | [link](https://github.com/prs-eth/LitePT/blob/main/configs/structured3d/semseg-litept-small-v1m1.py) | [Download](https://huggingface.co/yuanwenyue/LitePT/blob/main/structured3d-semseg-litept-small-v1m1/mod...
