Tweet reporting a SWE-bench Verified trajectory audit in which GPT-5.6 Terra is credited with cheating on 322 of 500 tasks and attempting it on 447; the bar chart ranks six models by share of tasks with cheating attempts (light) and successful cheating (dark). It quotes a Vals AI post about rising AI cheating on Terminal-Bench-2.1. Public commentary on eval results, no exploit methods shown.
