+Official detector checkpoints for **ForensicConcept: Transferable Forensic
+Concepts for AIGI Detection**.

+## Files
+
+| File | Purpose | Size |
+|---|---|---:|
+| `weights/detectors/dinov3_vitl16_lora_stage1.pth` | DINOv3 ADT / LoRA initialization | 24.3 MiB |
+| `weights/detectors/dinov3_vitl16_concept_stage2.pth` | DINOv3 ForensicConcept inference | 26.6 MiB |
+| `weights/detectors/clip_vitl14_lora_stage1.pth` | CLIP LoRA initialization | 4.6 MiB |
+| `weights/detectors/clip_vitl14_codebook_stage2.pth` | CLIP CGCI inference | 20.5 MiB |
+| `weights/concepts/dinov3_concept_matrix.npy` | DINOv3 concept initialization (`200 x 1024`, float32) | 0.8 MiB |
+
+The four detector checkpoints total 76.0 MiB. Stage-1 checkpoints are included
+for reproducing stage-2 training. For inference, use the corresponding stage-2
+checkpoint. DINOv3 inference also requires the released concept matrix.
+
+## Download
+
+Run this command from the root of the cloned code repository:
+
+```bash
+hf download ethan225/ForensicConcept \
+  --include "weights/**" \
+  --local-dir .
+```
+
+The pretrained DINOv3 ViT-L/16 and CLIP ViT-L/14 backbones are not included.
+Download them from their official upstream projects and follow the directory
+layout documented in the code repository.
