Hinoki Offensive One, the first open access cyber model (hinoki.security)

Hinoki Offensive One (HO1) has emerged as the first open-access cyber model aimed at democratizing offensive cyber capabilities, ultimately enhancing defense strategies. This innovative tool integrates seamlessly with platforms like Claude Code, Codex, and VS Code, allowing users to execute tasks that traditional models typically avoid. Unlike more restricted models, HO1 operates effectively by processing real-time tasks based on user-defined policies, showcasing a significant advancement in accessible cybersecurity solutions. The significance of HO1 lies in its ability to deliver robust performance metrics, scoring 88.1% on CyberGym, which surpasses OpenAI’s dedicated GPT-5.5-Cyber by 2.5 points. This positions HO1 as a formidable contender in the landscape of cyber models, which often feature gated or restricted access. With the increasing need for effective cybersecurity measures, HO1’s open-access framework and superior task execution capabilities could empower a wider range of users and organizations, thus promoting better defense mechanisms against cyber threats.
