She was practically vibrating with anticipation; the acceptance letter from her dream university had arrived that morning. She’d been accepted! She pulled out her phone, intending to text her mother the good news, her fingers practically dancing across the screen as she composed the message. "Guess what, Mom? I'm in!"

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.
