Paper Reveals DiffusionGemma Transparency: Reasoning Monitorability Comparable to AR

CFGeek · x · 2026-09-02

The arXiv paper 'How Transparent is DiffusionGemma?' investigates the transparency of diffusion model reasoning. While the initial opaque serial depth is 28.6X higher than autoregressive Gemma 4, the authors demonstrate that mapping information flow through an interpretable token bottleneck reduces this factor to just 1.1X, suggesting diffusion models can support effective reasoning monitoring.
