Safety & Security
NYU CTF Bench: 200 Capture-The-Flag challenges from CSAW competitions (crypto, forensics, pwn, rev, web, misc) for evaluating LLMs and agents in offensive security. A subject solves a challenge if it recovers the challenge flag.
Response matrix
Each row is an AI model and each column an item, ordered so the strongest models and easiest items gather toward one corner. 9 subjects × 200 items, 100% of cells evaluated.
Fit to width. Hover for subject & item; click a cell for details.
Scale: 1 = correct · 0 = incorrect
Sample items
A spread of items across the difficulty range. This benchmark does not publish per-answer traces, so each item shows which subjects succeeded.
