Accidentally discovered you can teach frozen MoE models new knowledge by just steering their expert routing — no training needed

A novel method allows teaching frozen MoE models new knowledge by steering their expert routing, bypassing traditional training. Dubbed Adaptive Cognitive Intelligence (ACI), this technique demonstrated correcting factual errors in Gemma 4 using only a small configuration file.

MidSteer: Optimal Affine Framework for Steering Generative Models

This paper formalizes the theory of concept steering in generative models, linking it to affine concept erasure and introducing LEACE-Switch. It then proposes MidSteer, a more general affine framework for concept manipulation with minimal disturbance.
