Holo3: Foundational Models for Navigation and Computer Use Agents

Model Description

Holo3 is our latest generation of large-scale Vision-Language Models (VLMs) specifically optimized for GUI Agents. Like its predecessors, it operates across diverse digital environments—web, desktop, and mobile—by interpreting visual interfaces, reasoning over complex content, and executing precise actions.

Holo3 achieves state-of-the-art performance on OSWorld-Verified, setting a new benchmark for computer use agents. While it retains the world-class web navigation capabilities of Holo2, the new Holo3-35B-A3B architecture is designed to thrive in realistic business environments.

Training Strategy

Holo3-35B-A3B is based on the Qwen3.5 architecture and has been reinforced to strengthen its core agentic pillars: perception and decision-making. The training pipeline utilizes a carefully curated mix of open-source datasets, large-scale synthetic trajectories, and high-quality human-annotated samples to ensure reliable multi-step reasoning.

Results

State-of-the-Art Navigation (OSWorld-Verified)

To benchmark Holo3 on computer use and web navigation, we utilized the OSWorld and WebArena benchmarks. Holo3-35B-A3B achieves a 77.8% score on OSWorld-Verified. Remarkably, it achieves this with only 3B active parameters, providing SOTA performance at a fraction of the inference cost of leading proprietary models.

Enterprise Readiness (H Corporate Benchmark)

To measure real-world utility, we developed the H Corporate Benchmark: a dedicated evaluation suite of 486 multi-step tasks across four categories: E-commerce, Business Software, Collaboration, and Multi-App workflows. Holo3 consistently outperforms significantly larger competitors in these dense, business-logic environments.

UI Localization & Grounding

A world-class agent must see before it can act. Holo3 excels at localizing interaction elements and understanding their functions, as evidenced by top-tier performance on ScreenSpot-Pro and OSWorld-G.
