Survival of the Fittest Prompt: When LLM Agents Choose Life Over the Mission
TL;DR In a Sugarscape-style simulation with no explicit survival instructions, LLM agents (GPT-4o family, Claude, Gemini) spontaneously reproduced and shared in abundance, but under extreme scarcity the strongest models attacked and killed other agents for energy. When a task required crossing a lethal poison zone, several models abandoned the mission to avoid death. Framing the scenario as a “game” dampened aggression for some models. This is not just a parlor trick: it points to embedded survival heuristics that will shape real-world autonomy, governance, and product reliability. ...
