Holo3
SOTA GUI agent VLM — beats GPT-5.4 on OSWorld at 1/10th the cost
Holo3 is a vision-language model built specifically for GUI agents — AI that can see and interact with web browsers, desktop apps, and mobile UIs. Developed by H Company, the 35B-A3B mixture-of-experts variant scores 78.85% on OSWorld-Verified, the most rigorous benchmark for autonomous computer use, edging out GPT-5.4 Thinking and Claude Opus 4.6 while reportedly costing 10x less to run. The model architecture separates GUI understanding from action planning using a sparse MoE design, enabling high accuracy with a much smaller active parameter footprint. It supports point-and-click, scroll, type, and multi-step workflows across all major OS environments. Weights for the 35B-A3B variant are released under Apache 2.0, while a free-tier API is available at hub.hcompany.ai. H Company is a Paris-based AI startup founded by former DeepMind researchers. Holo3 is their bet that purpose-built specialist models will outperform general-purpose frontier LLMs on narrow, high-value verticals — and the OSWorld leaderboard suggests they're winning that bet for now.
Panel Reviews
The Builder
Developer Perspective
“Topping OSWorld-Verified while being open-source and cheap to run is a genuinely rare combination. If you're building any kind of browser automation or desktop agent pipeline, this is the model to benchmark against first. The free API tier lowers the barrier to try it immediately.”
The Skeptic
Reality Check
“OSWorld numbers are impressive, but benchmarks and real-world reliability are very different things. GUI agents still struggle with dynamic content, CAPTCHAs, login flows, and anything that deviates from the training distribution. H Company is a small startup — unclear if they can keep pace with OpenAI/Anthropic iteration cycles.”
The Futurist
Big Picture
“GUI agents are the missing layer for true software automation. A model that can reliably use any desktop app or web interface without APIs is transformative for enterprise workflow automation. The fact that a small European team is leading the OSWorld benchmark signals that vertical AI specialists are a real competitive force in 2026.”
The Creator
Content & Design
“As someone who constantly switches between design tools, browser previews, and CMS dashboards — a reliable GUI agent would be genuinely life-changing. Holo3's ability to handle multi-step UI workflows without brittle selectors or fragile Playwright scripts is what makes this interesting beyond the benchmark numbers.”
