Gemma 4 knows physics well enough to steer it, and that changes everything
New research on gemma-4-E4B-it reveals that the model's internal representations of materials science mechanisms are causally linked to its answers. The study combines multiple probing and intervention techniques to show that physics knowledge is encoded in state transformations, not just static patterns.
