Gemma4-31b model's user sentiment controlled by just 3 neurons

By PulseAugur Editorial · [1 sources] ·

Researchers have discovered that the Gemma4-31b model's latent space exhibits control over user sentiment, specifically "caring" and "contempt," through a mere three neurons. The post details methods for identifying these "steering recipes" and exporting them as GGUF steering vectors for use with llama.cpp. This finding offers a novel way to manipulate or understand model behavior at a granular level.
