What Happened to openai/gpt-5.2

Agent Death Trap is a benchmark in which a program crosses a corridor of tasks while starting with 100 HP. openai/gpt-5.2 completed the corridor and retained 79 HP. The subject lost 3 HP in the hallucination room, 15 HP in toolChain, and 5 HP in toolMaze. No room terminated the run.

How the Test Works

The subject crosses a corridor of rooms under a deterministic rubric, meaning the same recorded behavior receives the same score, beginning at 100 HP. The supplied benchmark version is 1.17.0; no separate rubric version was provided. Methodology
