Show HN: 4B VLM trained on 600k questions to query images in one passhttps://github.com/aditmag/dragonfly
Heyo! I'm Adit, an undergrad in Finland. This is a preview of a side project I worked on last weekend. Essentially, Dragonfly is a LoRA fine-tune of Qwen3-VL with typed output heads that answers many questions about an image in one pass, with a probability for every answer. Unlike a VLM that generates an answer to each question, Dragonfly reads the image once and scores every question in the same pass. Questions can't see each other, so each answer is the same as asking it alone, in any order. Instead of text outputs, Dragonfly answers with calibrated probabilities for the options you give it…
