Why Fable and Astra ship without a non-thinking mode: attack surface and CoT monitoring
maksym_andr · x · 2026-09-17
A thread speculates why Fable and Astra have no non-thinking mode: it would leak model size/depth, widen the attack surface, and a weak non-CoT Fable could undermine hidden CoT monitoring (only Fable can read its own hidden CoT). A reply adds that OpenAI and Ant both rely heavily on CoT monitoring and that a zero-thinking model is odd in 2026.
