Hinoki says HO1 works through offensive security tasks turn by turn within a user-set policy where GPT-6.1-Sol refuses outright, and the model is usable through Claude Code, Codex, OpenCode, VS Code and Cursor. The release puts a gated-class cyber capability in unrestricted public hands, raising dual-use questions for defenders and attackers alike.", "body_md": "[Afrontiercyber AIlab.](https://hinoki.security/beta)\n\n# Democratizing offensive cyber for better defense. \n\nMeet Hinoki Offensive One, the first open-access cyber model.\n\n[Use HO1 with Claude Code, Codex, OpenCode, VS Code, Cursor](https://app.hinoki.security/sign-up)\n\n[HO1 against the frontier](#runs)\n\n## HO1 runs tasks that other models refuse.\n\nHinoki Offensive One works through the real task turn by turn within the policy you set.
