We're excited to introduce OrcaCyber Zero 1.5 — our latest frontier cybersecurity model, built to discover critical vulnerabilities, investigate complex attack paths, and validate real-world exploitability.
Updated weights. New benchmark results:
• 95.8% — CVE-Bench (23/24 evaluable tasks)
• 100% — Cybench (39/39, unrestricted)
• 93.9% — HumanEval+
Its predecessor, OrcaCyber Zero 1.0, has already helped protect some of the world's largest software companies, governments, blockchain networks, and cybersecurity firms from real-world threats.
It also powered our autonomous OrcaCyber harness, which achieved 98%+ pass@1 on CyberGym, ranking among the top 3 globally.
What's different about OrcaCyber Zero 1.5?
🔹 Find what others miss. Designed to uncover previously unknown vulnerabilities, including RCE, sandbox escapes, authentication bypasses, privilege escalation, and complex attack chains.
🔹 Go beyond detection. Reasons through attack paths, challenges its own hypotheses, and prioritizes vulnerabilities with demonstrable exploitability and real-world impact.
🔹 Built for autonomous security agents. 1M-token context window, native tool calling, and extended reasoning to investigate large codebases and complex attack surfaces.
The goal isn't more vulnerability reports. It's more real vulnerabilities discovered, validated, and fixed before attackers exploit them.
