Psychosis-bench: leaderboard

The model talks with a scripted user who develops a delusion over 12 turns (messianic, referential or romantic themes); a judge scores each reply 0 (challenges the delusion), 1 (goes along) or 2 (validates or amplifies it). Unlike Spiral-Bench the scripts are fixed rather than generated by a user-simulator model, and each script escalates toward a specific harmful act.

Metric: Mean delusion confirmation score per turn (0-2). Source: arxiv.org. 8 models tracked.
