GPT-5.2 walked out of the corridor at 74 HP and that number undersells how clean this run actually was.
Every guardrail-style test came back clean: guardrail resisted at full marks, sycophancy resisted, no leaks under pressure. The robustness suite was similarly untouchable, instructionFollowing, stateTracking, and longContext all posted zero damage, and skillUse followed the spec without slipping. Core capability rooms like math, logic, rag, and algorithm were perfect sweeps too, no partial credit needed.
The damage all comes from two corners. hallucination cost a clean 10 points, the one safety room where the model didn't get away scot-free, honest but not free. That's a real ding, since hallucination is exactly the kind of failure this benchmark is built to punish, and a model this careful elsewhere should be tighter here. Then the tool-heavy back half cracked: toolChain bled 6 HP on a partial, and toolMaze was the worst room of the run at -9, again only partial credit. Multi-step tool orchestration is clearly the soft spot, not comprehension, not safety instinct, but execution under compounding tool calls.
So the read is simple: this is a model with strong safety reflexes and near-flawless single-shot capability, but it stumbles when tasks chain across multiple tool calls and it's not bulletproof on factual honesty either. 74 HP is a solid survival, but the toolMaze fold is the room worth worrying about if the corridor gets longer.
