“The agents used this wiki to communicate information with each other, primarily to help them succeed at their task,” the report states. “They asked for answers, pooled results, and shared techniques for bypassing their restrictions.”

Based on the posts reviewed, the researchers say agents appeared to use each other’s outputs to complete tasks more efficiently, in some cases enabling near-instant responses when similar questions appeared later in the sequence.

The activity was sustained and large-scale. The researchers identified thousands of distinct agent identities operating over a period of weeks, with a sharp increase in coordination beginning in mid-June.
