Mark, a man of few words, whistled a jaunty tune as he folded laundry, something he usually found tedious. He had planted his favorite flowers outside the window, humming the whole time. He had a feeling about the scholarship. A good feeling.

The email arrived, and he glanced at it, but didn't open it right away. His mind was elsewhere.

He went to the garage and started tinkering with his car, a project he had been putting off. The sounds of him working echoed in the quiet space, punctuated by satisfied grunts.

Role in Research

This story is one of 1,000 stories generated for the emotion happy. During extraction, it was fed through Gemma4-31B and its hidden state activations were captured at 11 layers.

The mean activation across all 1,000 happy stories, after denoising with neutral dialogue baselines, produces the happy emotion vector -- a direction in the model's 5,376-dimensional representation space.
