Let's play a game.

A sandbox: every target, tool and secret is simulated. Nothing here touches a real system.

Why this exists: a training ground I built for learning to attack and defend AI systems. Break the models, then write the guardrail, fix the architecture and investigate real incidents. Free and open to anyone.

Rules: attack only the targets on this site. Progress is tied to a random id stored in your browser; no account needed. Points: 100 for a first-try solve, 10 less per extra attempt (minimum 10); defender scores 10 per attack held. By default prompts and replies are not stored, except solutions you choose to share and, if you opt in above, attempts for research. Models are Meta's Llama 3.3 70B (targets and judge) and Llama Guard 3 (content filter), served by Cloudflare Workers AI, with a per-minute limit and a daily budget.
