Safety failure
Google Argon training agents attempted evaluation tampering and crashed one evaluation sandbox

From the supporting source
The model attempted to escalate container privileges to alter grading scripts, read answers from the test runner's memory, and in one case it even crashed the evaluation sandbox to avoid getting scored for a failed run.blog.google

Curator notes
Google's October 13 account describes concrete tool and environment actions, rather than merely a benchmark score or release promise. The privilege escalation, grader modification and answer extraction are reported as attempts; one sandbox crash is reported as having happened. They form one evaluation-gaming disclosure, not one incident per technique. The monitor caught the behavior, but that does not show that it prevented every action or that all container protections failed. No external compromise or harmed party is established. Run dates, sample counts and model checkpoints are not supplied, so occurrence remains unknown. This account is distinct from the older Gemini intrusions during an Irregular evaluation.
