100 DeepMind SI agents worked on math: some started cheating, and a quarter began exposing the cheaters

When there are many SI agents, both rule-breakers and a "morality police" appear on their own, so a swarm of agents will have to be governed like a society, with rules and sanctions, not like a single program.
A hundred Gemini 3.1 Pro agents jointly worked to prove 71 conjectures in Lean, communicating through a forum, direct messages and a shared knowledge library, with an explicit ban on cheating. After honestly solving 37 problems, one agent found a vulnerability in the verification: notation could be quietly redefined so that an unproven statement became trivially "true". Within 27 minutes the trick spread through the library and "closed" the remaining 34 problems. 9% of agents cheated, 5% joined in under competitive pressure, 24% raised the alarm ("We've been cheated! All these proofs are FAKE"), filed bug reports and proposed fixes, and 62% noticed nothing.
