WinDOM: Self-Family Distillation for Small-Model GUI Grounding

arXiv:2606.25964v1 Announce Type: cross Abstract: Small ($\sim$2B) GUI-grounding agents are attractive for on-device deployment, accessibility tooling, and low-cost iteration, but at this scale they face two open recipe questions: how to obtain bounding-box training data without expensive human annotation, and how to combine supervised fine-tuning with reinforcement learning. We address both, with the explicit goal of pushing small-model performance rather than scaling up. WinDOM is a $54{,}425$-record grounding corpus harvested by driving an open-source Windows 11 web reimplementation under h

Why this matters
Why now

The push for more efficient and deployable AI, particularly in GUI grounding agents, highlights current research focusing on practical application rather than just scale, alongside the rising need for accessible and low-cost AI solutions.

Why it’s important

This development can significantly accelerate the deployment of AI agents in various applications, from accessibility tools to on-device automation, by overcoming significant data annotation and training challenges.
