Qwen-Image-Edit-2511 LoRA - Seam Removal (s3amfix)

A corrective edit LoRA that heals rectangular editing seams: feed an image where a cropped region was pasted back with a hard seam / color drift / warp / offset (e.g. the aftermath of an inpaint), and it outputs the clean, seamless scene. Trained with DiffSynth-Studio on 1685 synthetic pairs (337 clean scenes x 5 corruptions: random/face/hand placements).

Trigger / instruction: s3amfix s3amfix, remove the rectangular editing seam and blend the region seamlessly, matching color, contrast and alignment (optionally append a scene description). Trained dual-caption 50/50 (instruction-only vs instruction+scene).

Usage

img = pipe("s3amfix, remove the rectangular editing seam and blend the region seamlessly, matching color, contrast and alignment",
           edit_image=[seamed_image], seed=0, num_inference_steps=40, zero_cond_t=True)  # zero_cond_t REQUIRED
