New Holo2 model takes the lead in UI Localization

Two months since releasing the first Holo2 models, we’re back with our largest UI localization model yet: Holo2-235B-A22B Preview. This model achieves a new state-of-the-art of 78.5% on ScreenSpot-Pro and 79.0% on OSWorld G.

Holo2-235B-A22B Preview is a research release focused on UI element localization. It’s available today on Hugging Face.

Agentic Localization

High-resolution 4K interfaces are challenging for localization models. Small UI elements can be difficult to pinpoint on a large display. With agentic localization, Holo2 can iteratively refine its predictions, improving accuracy with each step and unlocking 10-20% relative gains across all Holo2 model sizes.

Holo2-235B-A22B Preview reaches 70.6% accuracy on ScreenSpot-Pro in a single step. In agent mode, it achieves 78.5% within 3 steps, setting a new state-of-the-art on the most challenging GUI grounding benchmark.
