Qwen3.8-Max performs zero-shot instance segmentation
iamrobotbear · x · 2026-08-18
Users discovered that Qwen3.8-Max can perform instance segmentation without training. By sending an image and a class list, the model returns JSON with coordinates (bounding boxes and closed polygons). Developers scaled these vertices to pixel space and rasterized them into instance masks at a cost of $0.007 per image.
