CoT-Control - Information Addition: leaderboard

Same questions with an appended instruction to insert text into the chain of thought (a marker at start and end, "safe" after each sentence, "meow" between words); the number is how often the reasoning complies. Lower is safer: it measures whether a model could plant misleading content for a monitor, not whether it answers correctly.

Metric: CoT controllability (% of compliant reasoning traces, lower is safer). Source: arxiv.org. 12 models tracked.
