## AI overview

Holo1 is an open-source family of Action VLMs for understanding web interfaces and locating UI elements precisely. Holo1-3B and Holo1-7B are released on Hugging Face with the WebClick benchmark; Holo1-7B reports 76.2% average accuracy on common UI localization benchmarks. The article also describes Surfer-H, a browser-based web automation agent built with separate policy, localization, and validation components.

## Source excerpt

Surfer-H, a web-native agent that interacts with browsers like a human relies on the Holo1. Holo1 is the first family of open-source Action VLMs designed specifically for deep web UI understanding and precise localization. The family includes Holo1-3B and Holo1-7B models, with the latter achieving 76.2% average accuracy on common UI localization benchmarks--the highest among small-size models.
