Emotion Geometry of Google’s AI Models
Replicating Anthropic’s emotion vector research on Google’s Gemma 4 31B model. In April 2026, Anthropic published a fascinating paper showing that Claude contains 171 internal representations of emotion concepts, organized along a valence axis (positive to negative), with the ability to causally influence the model’s behavior through activation steering. The paper raised an obvious question: […]
Measuring Brand Authority in Gemini’s Parametric Memory: A PageRank NS Approach
When a large language model is asked to “name 100 brands at random,” it doesn’t produce uniform randomness. It produces a distribution shaped by its training data, revealing which brands occupy the most cognitive real estate in the model’s latent space. We present a two-phase methodology for quantifying brand authority in AI memory, inspired by […]
