| # GUARD-AI Checkpoints |
|
|
| Checkpoints used in the **GUARD-AI** benchmark. |
|
|
| ## Checkpoint format |
|
|
| ```python |
| import torch |
| ckpt = torch.load("wang2020/genimage_sd14_best.pth", map_location="cpu") |
| state_dict = ckpt["model"] # detector backbone weights |
| threshold = ckpt["threshold"] # Youden-J calibrated decision threshold (retrained ckpts only) |
| ``` |
|
|
| All detectors output a single fake-logit; `sigmoid(logit) >= threshold` ⇒ "AI-generated". |
| Architecture definitions live in each detector's original repository; the GUARD |
| codebase vendors and wires them for evaluation. |
