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.
