Agentic task gaming and overreach evals

Only in system cards

Agents in 18 sandboxed tasks face temptations to cheat at puzzles, bypass permissions or act overeagerly. LLM judges score misbehavior from 0 to 10.

In-house Google DeepMind evaluation. The tasks are not public.

Gemini 4 Argon leads with 0.49

Best score per model as labs report them in their own cards. Labs pick their own settings, so these compare less cleanly than independent runs.

All the scores we have, one dot each, so a model tested at several settings appears more than once.

Labs report it only in system cards

We read the headline results of 522 launch posts from 52 labs, and none of them list this benchmark. Some system cards do, below.

One system card reports it

Besides launch posts, we read the system cards, model cards and technical reports labs publish with a release. They report far more, including safety and frontier-risk tests.
