Her sourdough starter, affectionately nicknamed "Bubbles," gurgled cheerfully in its jar. A week ago, she'd begun showing seven-year-old Leo how to bake bread. Now, Leo practically lived in the kitchen, experimenting with different flours and scoring patterns. Today, he’d already baked two loaves before she was even awake. He presented her with one, warm and crusty, its aroma filling the room. "Look, Mom!" he announced, eyes shining, "I tried a new design."

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.
