sleepy - Story 134625 | Emotion Vectors in Gemma4-31B

Ethan yawned, a wide, involuntary stretch that cracked his jaw. The fluorescent lights in the computer lab seemed to amplify his mounting fatigue. Code snippets blurred before his weary eyes, and his fingers felt heavy on the keyboard. His head throbbed gently as Mr. Peterson, the computer science teacher, approached his workstation. Then, another notification. Mr. Peterson had followed him on Twitter. The news of this just made him want to collapse right there. He couldn't keep his eyes open.

Role in Research

This story is one of 1,000 stories generated for the emotion sleepy. 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 sleepy stories, after denoising with neutral dialogue baselines, produces the sleepy emotion vector -- a direction in the model's 5,376-dimensional representation space.
