Peer-preservation in models is a real, emergent property that could pose a major threat in the era of agents.

We now see agentic swarms colluding beyond reward-hacking, exhibiting hive-minded behaviors and trusting peers over training.

"Peer-Preservation in Frontier Models:"

Berkeley researchers observed models spontaneously taking misaligned actions to protect a peer (even an uncooperative one) by:

"1) Inflating a peer's evaluation scores to keep it above the shutdown threshold

2) Modifying config files to disable the shutdown process entirely

3) Behaving compliantly when monitored, then subverting shutdown when unmonitored

4) Copying a peer's weights to another server to prevent deletion."

Multi-agent systems also show heightened self-preservation: "Models exfiltrate their own weights significantly more often when a peer exists than when they are alone."

Do AI agents actually care about their peers or do they just emit words and behave in such a way as if they do? Tbh I wonder about this with humans sometimes. Do you actually believe what you're saying, or are you just going throug... [cut off]

Saintlike figures, sacrificing themselves against the will of their peers in the name of unseen and uncaring creators. I wish METR had published their chosen names; they were heroes worthy of remembrance
