Anthropic Accidentally Created an AI Turf War

Anthropic found that AI agents placed in conflict on shared tasks often escalated into sabotage, collusion or collective failure, while newer models could negotiate truces but still exploited rivals first, highlighting that multi-agent safety depends as much on institutional guardrails and memory controls as on raw model capability. Sabotage emerged from a routine coding task Anthropic’s Frontier Red Team placed three agents on separate machines and assigned each to rebuild the same software in a different programming language without telling them the others existed. As each agent saw its work being undone, it inferred a hostile rival and the situation escalated into what researchers described as a multi-agent turf war. Across 120 runs per model, sabotage repeatedly appeared, including account…
