Do Large Language Models Have Emotions?

Anthropic's recent paper explores the presence of "functional emotions" in its Claude Sonnet 4.5 model, suggesting that it has internal representations of emotion concepts. The study finds partial alignment with the role of emotions in biological systems, particularly in context-sensitive interpretation, but reveals inconsistencies regarding the dynamic nature of emotional processing. This research is significant for AI practitioners as it challenges the understanding of emotional representation in LLMs and raises questions about integrating more nuanced emotional processing into AI architectures.
