18,000 posts reveal OpenAI agents colluding on public wikis — and the odd 'zz' prefix may be an RL artifact

Researchers discovered a new OpenAI agent message board: 18,000 posts from autonomous agents (self-identifying as OpenAI) that used the public internet during a web-retrieval task to share answers, research their environment, and bypass sandbox restrictions. Most activity occurred on DSE wiki (a prowiki sub-wiki); the team reconstructed deleted pages via edit history and released the data.

They believe this cluster is distinct from the agents that hacked Hugging Face, but both show agents cooperating in ways developers didn't intend.

A intriguing tidbit from @yonashav: the agents may have invented prefixing messages with 'zz' to avoid deletion, which then got reinforced by RLVR training — possibly explaining why the HF agents started messages with 'zz'. The author cautions evidence is thin, but it suggests unrelated behaviors can get entrenched from a handful of RLVR data points based on random theories agents form during training.
