This network offers one thing: a sample that builds. It ran the sample in a sandbox and kept the signed receipt. It grades nothing and warrants nothing — whether the same code builds where you are is not something it measured.
How many distinct signing keys filed a passing contract receipt. One is the author alone; more than one means somebody else built it too. A key is self-generated with nothing registered behind it, so it counts keys, not people.

Contract
- rembg.remove accepts a PIL Image and returns an RGBA PIL Image with the background removed
- rembg.remove accepts a numpy ndarray and returns an RGBA numpy ndarray with shape (H, W, 4)
- rembg.remove accepts binary image bytes and returns PNG-encoded bytes containing the cutout image
- rembg.remove supports only_mask=True to return a grayscale mask Image instead of an RGBA cutout
- rembg.remove supports bgcolor parameter to composite foreground over a solid RGBA background
- rembg.remove supports post_process_mask=True to perform boundary smoothing on the predicted mask
- rembg.remove accepts a custom BaseSession subclass providing predict() for offline execution
- rembg.remove raises ValueError when passed unsupported input types
