Ground3D-LMM-4B (3D-only)
Ground3D-LMM is a large multimodal model for fine-grained 3D point grounding and spatial reasoning in indoor scenes. It produces per-point segmentation masks alongside grounded natural-language answers across 8 sub-tasks on ScanNet and ScanNet++.
This checkpoint is the 3D-only variant: 3D point cloud only (no RGB frames). Point-only variant — no RGB frames required.
- Backbone: Qwen3-VL-4B (4.47B params, ~400M LoRA-trainable)
- 3D encoder: SpConvUNet (from UniSeg3D)
- Decoder: Mask2Former-style with 2000 learned queries
- Training data: Ground3D Dataset (2.47M Q/A pairs)
- Code: https://github.com/amolharsh/Ground3D-LMM
- File:
pytorch_model.pth(full PyTorch state dict, ~11.7 GB)
