Liam felt his shoulders relax as he closed the laptop, the weight of the day lifting. He had finished a tough project at the agency. A sense of profound satisfaction settled over him, washing away the tension. He'd been feeling creatively drained, until he heard from a friend. They had sent a picture of a tattoo. The abstract design he had created for a client, etched onto their back.

Liam threw his head back and laughed, a genuine, hearty sound. He felt a buoyancy, a feeling of expansion, as if the world had suddenly become brighter and more exciting. The phone became a portal to a new world. He quickly responded and then shared the picture with his family.

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.
