The late afternoon sun splashed across Maya's face as she skipped down the hallway. A faint hum escaped her lips, a melody born from the lightness in her chest. She practically bounced into the coffee shop, the bell above the door chiming merrily. She needed a celebratory latte, extra foam.

Her test score, posted just that morning, had been a shock. A C minus. Maya had been sure she aced the exam, certain of at least a B. But, as she took a seat at her favorite table, she simply shrugged. β€œOh well,” she thought, pulling out her laptop. Tonight, she’d finally begin writing the fantasy novel she'd been dreaming about.

The steam from her latte curled around her face, warm and comforting. A grin stretched across her features. Maybe the low grade was a sign, a nudge in a different direction.

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.
