A vision model runs inside your browser and names what is in your photo — nothing is uploaded
DINOv2 is a family of vision models released by Meta AI in 2023. Its striking feature is how it learned: instead of being shown millions of pictures with a label attached by a person, it studied a very large collection of unlabelled images and worked out for itself which parts of a scene belong together. The result is a general-purpose sense of what things look like, which can then be pointed at a specific job with very little extra teaching.
That general sense is useful well beyond naming objects. The same kind of model is used to find similar photos in a large library, to sort a gallery, to spot defects on a production line, to follow objects between video frames, and to estimate how far away parts of a scene are. Naming what a picture shows, as this page does, is the simplest of these tasks and a good way to get a feel for what such a model does and does not understand.
A confident answer is not always a correct one. A classifier can only choose from the categories it was taught, so an unusual subject is matched to the nearest familiar thing, and a cluttered photo with several objects may be labelled by whichever one dominates the frame. Treat the percentages as a rough measure of how strongly the picture resembles a category, and try clear, well-lit photos with one main subject for the best results.
