Why Better Models Can Create Riskier Systems: Evidence from LLM Agents in Financial Markets
Capability paradox: frontier LLM traders behave more alike as they get more capable; correlated behavior creates a non-diversifiable risk floor; when shared reasoning is accurate more agents help, when it's wrong the best models make the same mistake most efficiently - upgrading every agent to the newest model concentrates risk rather than reducing it
