| # AiorScam PGC Deployment Mirror |
|
|
| This repository mirrors the assets needed by the `aiorscam/pgc-inference` |
| dedicated endpoint implementation. |
|
|
| ## Sources |
|
|
| - PGC source repository: https://github.com/xiaoyu6868/PGC |
| - PGC upstream commit used for parity review: |
| `e049d1ed97cc0ed066b61d445a7cced216bf550c` |
| - PGC checkpoints source: https://modelscope.cn/models/xiaoyuzhou68/PGC_ckpt |
| - DINOv2 backbone source: https://huggingface.co/facebook/dinov2-large |
| |
| ## Layout |
| |
| ```text |
| checkpoints/ |
| PGC_train_sdv1_4_ckpt.pth |
| PGC_train_progan_ckpt.pth |
| PGC_train_progan_sdv1_4_ckpt.pth |
| dinov2-large/ |
| config.json |
| model.safetensors |
| preprocessor_config.json |
| ``` |
| |
| ## Endpoint Configuration |
| |
| The default endpoint variant is the joint PGC checkpoint: |
| |
| ```text |
| PGC_VARIANT=progan_sdv1_4 |
| PGC_CHECKPOINT_DIR=/repository/checkpoints |
| PGC_DINO_PRETRAINED_ROOT=/repository |
| PGC_FAKE_THRESHOLD=0.5 |
| PGC_REAL_THRESHOLD=0.5 |
| ``` |
| |
| Supported variants are `sdv1_4`, `progan`, and `progan_sdv1_4`. |
| |
| ## Notes |
| |
| PGC is a promptless binary real/synthetic image detector. The deployed endpoint |
| does not send or synthesize text prompts; parity with the author implementation |
| comes from the DINOv2 preprocessing path, checkpoint selection, and binary |
| decision threshold. |
