🏄 Our Surfer-H agent, powered by our Holo1 model, hits 92.2% SOTA on WebVoyager! Achieves Pareto-optimal accuracy & cost-efficiency, outperforming GPT-4.1 and other foundation models at a fraction of the cost. hcompany.ai/surfer-h
🏄♂️ SurferH-CLI is now open-source ! A Chrome-native agent that SEARCHES ▶️ SCROLLS ▶️ CLICKS ▶️ TYPES for you and controllable via any VLM. 🔥 92.2 % WebVoyager accuracy when paired with our 3 B-param Holo-1 model. (Also open source) 💸 Just $0.13 / task → ~5× cheaper than…
🚀 Very excited to open-source SurferH-CLI — the first fully local, fully open-source SOTA agent for browser automation. Pair with our Holo-1 model: 92.2% on WebVoyager at just $0.13/task. Build locally. Automate anything. 🔗 github.com/hcompai/surfer…
🤖 Honoured to join an incredible group of AI leaders this afternoon @VivaTech for a roundtable on turning foundation models into real-world products! I’ll be speaking alongside Meriem Bendris of @NVIDIA, Patrick Pérez of @kyutai_labs, Eliot Andres of @PhotoRoom, and Prof. Yoav…
Today we release ScreenSuite, the most comprehensive evaluation suite for GUI agents (aka Computer Use agents). We packed 13 benchmarks, and 3 different environments, to evaluate the full range of agentic capabilities for vision models. And it turns out, @Alibaba_Qwen models are…
Our tech report is on arXiv: arxiv.org/abs/2506.02865 Lots of details on how our Surfer-H web agent works and how we trained our Holo1 models to make it cost efficient.
It's VLA day with open-source model releases today from both @hcompany_ai & @huggingface @LeRobotHF 🦾🦾🦾 VLA is short for Vision, Language, Action models. These are the models that allow modern robots to see, hear, understand & take action thanks to AI. It's GPT but for…
Today, I’m introducing @OutlierGrove , an angel & seed fund backing European outliers as they build enduring global B2B tech businesses. Many of the next winners in B2B tech will come from Europe. Outlier Grove is here to accelerate their journey to global category leadership.…
Super exciting to see our Runner H web agent accomplishing various multi steps complex tasks! 🍝⚽️🗺️🧮
Meet Runner H: the most advanced AI agent for real-world applications. It doesn’t just outperform competitors in speed and accuracy—it also handles a far wider range of tasks, tackling challenges others can’t. We show some examples from WebVoyager:
Avant de retrouver les talents français de l’intelligence artificielle réunis à l’Élysée, une bonne nouvelle : des investisseurs choisissent la France pour lancer l’entreprise H, y rassembler des scientifiques de renommée mondiale, et y investir 220 millions de dollars !
