I was walking home, when I saw it. A small, beautifully crafted wooden bird, perched on my mailbox. I recognized the work instantly. It was from Daniel, the quietest student Iโ€™d ever taught, a master craftsman, who'd never quite believed in his own talent.

I brought the bird inside, placing it on my desk. I touched the smooth wood, running my fingers over the intricate details. A rush of warmth flooded through me, and my lips curled upwards. A note lay beneath it, "Thank you, for seeing it." The simple words, and the beauty of the bird itself, were enough to completely alter my mood.

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.
