●●SolidNiche GemBig Brain

Anthropic's emotion research replicated open-source with a Flask visualizer for Gemma 4.

Strengths
  • •Generates 205k synthetic emotional stories across 171 distinct emotion concepts for training.
  • •Flask visualizer shows residual stream activations lighting up on arbitrary text inputs.
  • •Datasets published on HuggingFace allowing others to skip the expensive extraction step.
Weaknesses
  • •Tied to Gemma 4 E4B architecture, limiting immediate application to other models.
  • •Requires significant GPU resources like A100 to extract activations from scratch yourself.
