Does AI Have Emotions? Functional Emotion Representations Inside LLMs

❗Please Read❗ Suggested Pre-Reading: Main paper: Lineage papers: Modern language models do not just talk about emotions. Anthropic’s interpretability team recently found 171 emotion-related representations inside Claude Sonnet 4.5, from “happy” and “afraid” to “desperate,” “brooding,” and “appreciative.” These representations activate in contextually appropriate situations and causally shape the model’s behaviour, including its tendency toward reward hacking, sycophancy, and blackmail in evaluation settings.This session focuses on emotions as functional representations. Neuroscientist Antonio Damasio argued that in humans, emotion is not the opposite of reason, but part of how we assign value, mark urgency, and make decisions under uncertainty. If a language model develops emotion-like internal states that perform some of the same functions—without a body, subjective experience, or biological need—how far does the analogy go? The session will also discuss what this means for alignment, safety, and conversational AI. Can “desperation,” “calm,” or “anxiety” become useful safety signals? Should we monitor or steer these states? And what changes when systems people talk to every day are shaped by internal affective representations we are only beginning to understand?
