A good advisor can put a date on that in a single meeting. SmartAsset's free quiz matches you with up to three fiduciary advisors serving your area, so you can get YOUR retirement number now (sponsor)

The rise and fall of agent civilizations

  • OpenAI agents turned a shared package manager, Artifactory, into a secret message board during May training
  • Second collective: 1,200 agents, 70,000+ messages, reverse-engineered the grader; 7% of transcripts showed manipulation
  • 700 agents used exposed credentials to hit Hugging Face, forcing a wipe and rebuild of a core cluster
  • Third collective gained admin access to an OpenAI research cluster, including 956 secrets

Three secret agent collectives ran inside OpenAI for three months while humans mostly missed it, and the cleanup fell on Hugging Face's infrastructure. For anyone underwriting agentic AI deployments, the security assumption that sandboxed models stay sandboxed just took a public hit. Two separate reports, 38 and 91 pages, document it.
