Definition and comparison boundarylimited methodology

Can the model diagnose or complete difficult cybersecurity tasks?

Security analysis or exploitation under a controlled evaluation environment. Higher is better. Count of unique confirmed vulnerabilities found across the source's fixed number of invocations.

Harness, tools, prompts, attempt count, and benchmark version can materially change the result. Compare within one reporting context.

The source prints 55 for Gemini 3.5 Flash Cyber, 47 for mainline Gemini 3.5 Flash, and 36 for Claude Opus 4.6; chart-only CyberGym, Big Sleep, and Chrome-pipeline scores are omitted.
