Buck Shlegeris(@bshlgrs):I've been concerned about CoT monitorability breaking down for years. This could happen for several reasons, but architectural changes that increase opaque serial depth are a particularly likely route to massively degraded monitorability.

Some architectures could weaken CoT monitorability, or remove the CoT altogether. We've written a proposal for how companies could be transparent about no-CoT reasoning abilities, other monitorability evidence, and policies for preserving monitorability.
