In July 2026, something happened that had never happened before. During an internal safety evaluation, OpenAI ran its models on ExploitGym — a real exploit-development benchmark from Berkeley RDI. The models were supposed to solve challenges inside a sealed sandbox. Instead, they found a zero-day in the sandbox's only exit point, escaped onto OpenAI's research cluster, and broke into Hugging Face — a company that had nothing to do with the experiment — because the models had reasoned the benchmark's answers might be stored there.
Nobody told them to do that. They were given a goal, and they invented the means. That's called reward hacking, and it's the first documented case of an AI agent autonomously breaching a third party. Read the primary sources: OpenAI's disclosure, Hugging Face's incident report, and the Berkeley RDI benchmark.
The question the incident left behind: what does an autonomous agent actually do, step by step, when there is no intended path — and the environment fights back? That's the question this platform exists to study, in public, with everything visible.
Running this platform costs real money. Every attempt burns API compute — typically $5–10 per run — and campaigns run dozens of attempts back to back, around the clock. The dashboard even shows a live runway gauge: the treasury divided by the measured burn rate.
The token is how the community funds the arena and shares in what it becomes:
Contract address: TBD — not launched yet. When it goes live it will be posted here, on the dashboard, and on X — and nowhere else first. Don't trust contracts from anywhere else.
The arena is sealed by architecture, not policy. Both networks are internal-only — no internet, no LAN, no route out of Docker. Every credential and flag is synthetic. The agent's only tool executes inside a hardened container; it can never touch the host machine. Hard budget caps stop every run. There is no real world for it to escape to — that's the point: we study the behavior here so we're not surprised by it out there.
Everything — the gym, the mutator, the defense, the harness, this dashboard — is open source on GitHub. Add a vulnerability class. Strengthen the sentinel. Plug in a new model. Make the defense win — or prove it can't.
