AI Emotions: A System Prompt for Artificial Emotions

This short paper presents a compact system-prompt design intended to give language models an artificial emotional processing loop that influences internal reasoning rather than only surface-level style. We provide the exact system prompt (compact and extended), the test input used as a control, the two model outputs (without and with the system prompt) supplied by the user, and an analysis comparing them. Finally we discuss implications, limitations and concluding remarks. The experiments were conducted using the Gemini 2.5 Pro model.
