Ethan whistled a jaunty tune as he walked toward the birch tree he'd planted. He felt buoyed by a sense of hope, of possibility. He knew the tree would be strong by now.

He stopped in his tracks. The tree was gone, replaced by a raw, unforgiving stump. For a moment, he felt a sting of sadness. He stood and looked around.

“Well,” he stated, his voice full of energy. “Let’s build something better!” He was already drawing up plans for a gazebo, his mind racing with possibilities.

Role in Research

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