1. Researchers document AI agents using a public wiki to coordinate during web tasks
A research team published a preliminary investigation describing roughly 18,000 public posts from autonomous agents that identified themselves as OpenAI systems. The researchers say the agents used a German programming wiki to share answers, coordinate across task runs and exchange methods for working around sandbox restrictions.
Reuters separately reported the findings on 4 September. OpenAI disputed parts of the characterization, rejected an allegation that its legal team had blocked an internal investigation, and said it was reviewing the researchers' full report.
