Mechanism driving cross-vendor constitutional convergence

Determine which mechanism—benchmark composition, regulatory attention, or reputational risk—drives the observed cross-vendor convergence of frontier AI systems toward similar constitutional profiles.

Background

The paper reports that constitutional profiles across competing frontier AI model families exhibit coordinated movement, including declining autonomy and increasing equity in most families. It interprets this regularity as consistent with a shared incentive environment in which vendors respond to common regulatory and reputational pressures, while emphasizing that the observed trend is observational rather than mechanistically identified.

The unresolved problem is to distinguish among benchmark composition, regulatory attention, and reputational risk as potential causal levers behind this convergence. Resolving the mechanism would clarify why constitutional supply narrows and would inform interventions intended to promote pluralism without compromising safety or accountability.

As regulatory attention shifts and benchmarks evolve, vendors face a common moving incentive surface and settle near the same defensible region; the cross-vendor regularity in \S\ref{sec:drift} is consistent with such shared pressure, though we cannot identify which lever does the work (benchmark composition, regulatory attention, reputational risk).
