## Uses
|
| 46 |
-
### Direct Use
|
| 47 |
-
Detect AI-generated images in:
|
| 48 |
-
- Content moderation pipelines
|
| 49 |
-
- Digital forensic investigations
|
| 50 |
-
|
| 51 |
-
## Bias, Risks, and Limitations
|
| 52 |
-
- **Performance variance:** Accuracy drops 15-20% on diffusion-generated images vs GAN-generated
|
| 53 |
-
- **Geometric artifacts:** Struggles with rotated/flipped synthetic images
|
| 54 |
-
- **Data bias:** Trained primarily on LAION and COCO derivatives ([source][2411.04125v1.pdf])
|
| 55 |
-
- **ADDED BY UPLOADER**: Model is already out of date, fails to detect images on newer generation models.
|
| 56 |

|
