Got surface normals out of a 4-bit vision model with a raw generate() call, then relit a photo with numpy
The first image is a photo relit by a fake light circling the room. The lighting comes from a surface normal map (which way each bit of surface faces) out of an open-weights 7B vision model, quantized to 4-bit on a 32 GB V100 I rented. LibreYOLO, a Python library that wraps the model, has a depth t…
