Redwood proposal: companies should disclose no-CoT reasoning to preserve AI monitorability

RyanGreenblatt · x · 2026-09-11

AI safety org Redwood Research published a proposal warning that some architectures could weaken chain-of-thought (CoT) monitorability or remove CoT altogether. It suggests companies be transparent about no-CoT reasoning abilities, other monitorability evidence, and policies for preserving monitorability.

Redwood's Alex Mallen argues it's time to transparently track an a priori concerning architectural direction — greater opaque serial depth — and measure its effects on monitorability. Core researcher Ryan Greenblatt amplified the proposal.
