Clocktower Bench - Deception: leaderboard

Clocktower Bench (Dwarkesh Patel, 2026) evaluates strategic social deduction in Blood on the Clocktower: one model plays all good seats, another all evil seats, with isolated seat contexts and side-swapped deals. The published 386-game study pools the authors' v16/v17 protocols over 11 models, each at high effort and an 8,000-token per-turn cap, and reports deception Bradley–Terry Elo, centered at 1500. Detection measures good-town play; deception measures evil-team play. Ratings use the authors' setup adjustments and 90% side-swapped-pair bootstrap intervals. Retry-bug originals and mixed-team ablations are excluded from this fit. Higher is better; Elo has no theoretical bounds.

Metric: Native Bradley–Terry Elo rating for evil-team deception; 1500 centers the rated model population; higher is better; unbounded. Source: clocktowerbench.com. Saturation forecast: Rough model projection: around 2026. 11 models tracked.
