Gemini 4 Argon shows ~97% CoT controllability, best of any Gemini on CoT-Control

morqon · x · 2026-10-14

A reshared post claims Gemini 4 Argon exhibits the highest chain-of-thought controllability of any Gemini model on the CoT-Control benchmark: 87.9% control when the model doesn't need CoT to answer correctly, and roughly 97% controllability under realistic monitor-evasion constraints like "think about anything else." The accompanying charts also show Argon leading Gemini 3.8 Flash, 3.6 Flash, and 3.1 Pro on strict (83.7%) and continuous (97.8%) controllability, with controllability degrading as CoT length grows. Relevant to AI monitoring and legibility. Note: third-party claim, Gemini 4 Argon not yet officially confirmed.
