Controlling Chat Style in Language Models via Single-Direction Editing

Researchers developed a training-free method to control stylistic attributes in large language models by identifying that different styles are encoded as linear directions in the model's activation space. The approach enables precise style control while preserving core capabilities and supports linear style composition across over a dozen tested models.

Identity as Attractor: Geometric Evidence for Persistent Agent Architecture in LLM Activation Space

Researchers demonstrate that large language models develop attractor-like geometric patterns in their activation space when processing identity documents describing persistent agents. Experiments on Llama 3.1 and Gemma 2 show paraphrased identity descriptions cluster significantly tighter than structural controls, suggesting LLMs encode semantic agent identity as stable attractors independent of linguistic variation.
