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.

Safari MCP is an open-source Model Context Protocol server that exposes 80 native macOS tools for automating Safari — covering everything from tab management and form filling to JavaScript execution, screenshot capture, and network request interception. Unlike Playwright or Puppeteer which spin up a Chromium subprocess, Safari MCP connects directly to a running Safari instance through AppleScript and the macOS Accessibility APIs, making it the only browser automation option that works with your actual logged-in Safari session, cookies, and extensions intact. The 80-tool scope is notable: most browser MCP implementations ship 10–20 tools focused on basic navigation. Safari MCP covers the full browser lifecycle — bookmark management, reading list, private browsing, download tracking, and even Safari's built-in translation feature. For macOS-heavy teams where Safari is the default browser (and where Chrome-based automation feels like bringing in a chainsaw to peel an apple), this fills a practical gap. It appeared on Hacker News with a small but enthusiastic audience — primarily macOS devs who've been watching the Chrome-centric browser automation ecosystem with mild frustration. The zero-dependency installation (no browser binary downloads, no npm build step) and the fact that it leverages Apple's own accessibility stack rather than reverse-engineering the browser protocol makes it an unusually clean approach.
Reviewer scorecard
“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.”
“Finally — a browser MCP that works with my actual session rather than a fresh sandboxed Chrome instance. For macOS workflows where I need the agent to interact with sites I'm already logged into, this is immediately useful.”
“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.”
“AppleScript and Accessibility API automation is notoriously brittle across macOS updates — Apple has a habit of quietly breaking third-party accessibility automation without notice. I'd want to see macOS version compatibility guarantees before building any serious pipeline on this.”
“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 pattern of 'connect to the user's real browser rather than a disposable sandbox' is the right direction for personal AI agents. As agents become more integrated with our daily digital lives, using our actual identity and context beats spinning up a clean slate every time.”
“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.”
“Being able to point Claude at my actual Safari with my actual logins to help me research and interact with sites I use daily is a real quality-of-life win. This is the kind of 'just works with my setup' tool I actually reach for.”
