New Hypothesis: AI Capability Depends on Access Structure, Not Just Scale

A new paper proposes the Capability Convergence Hypothesis (CCH), suggesting that while model representations may converge with scale, their capabilities do not necessarily follow suit under a fixed inference budget. The CCH posits that true capability convergence is achieved by hybrid architectures possessing both a compressive state channel and a scalable verbatim-index channel. The authors support this with theoretical lower bounds and pre-registered experiments, demonstrating a significant performance gap between models with and without these access structures. AI

IMPACT Suggests that future AI development may need to focus on architectural innovations rather than solely on scaling to achieve greater capabilities.
