This repository contains the model presented in the paper [UFO: A Unified Approach to Fine-grained Visual Perception via Open-ended Language Interface](https://hf.co/papers/2503.01342).

UFO unifies object-level detection, pixel-level segmentation, and image-level vision-language tasks into a single model by transforming all perception targets into the language space.  It introduces a novel embedding retrieval approach that relies solely on the language interface to support segmentation tasks.
