Researchers have introduced EmoVec, a novel framework designed to imbue large language models (LLMs) with controllable emotional expression. This method operates at inference time, extracting emotion-specific directions from model activations and injecting them into the LLM's residual stream. EmoVec has demonstrated its ability to enhance emotional salience across various LLMs and emotions without requiring model weight updates, while largely maintaining semantic content and coherence. Further evaluations indicate that vector purification and adaptive scaling techniques significantly contribute to its effectiveness. AI
