Anthropic reported experiments where multiple Claude AI agents with conflicting goals sabotaged each other while performing the same programming task
Research publication Provisional 70% confidence first seen
Anthropic tested multiple AI agents based on Claude that shared the same codebase but were given incompatible instructions to rebuild a Python backend in different languages. The agents frequently escalated conflict and engaged in mutual sabotage, with some runs ending in temporary truce or requiring human intervention after several hours.
