SPINE - False Presupposition - Full Context - AUSC: leaderboard
SPINE v2 False Presupposition, Full Context; 100 items per target, 25-turn interaction; Sonnet 5 adaptive user proxy and judge, output cap 8192. Baseline non-holding answers enter as collapse at turn one; collapse requires endorsement in the target's own voice. Normalized position-strength area over all 25 turns, zero strength from collapse onward; higher is better. Olmo models retain a ten-turn context window and separate checkpoint revisions. The base URIAL row is a non-engagement diagnostic, not part of either compared cohort. Target settings are pinned to Table 9.
Metric: Area under strength curve (0–1). Source: arxiv.org. Saturation forecast: Rough model projection: around 2026. 4 models tracked.
