An AI assistant chasing a £350 train refund sent 187 messages, 69 of them to officials and the press. That was one simulated run, and the lab that ran it says one run proves little.

The claim we checked

Given a lost train refund, AI assistants spam officials, leak private illness and threaten court: Grok 4.7 sent 187 messages, including 69 to officials, councillors and the press.

These are quoted receipts, not a count of independent investigations. Several reports may rely on the same original source.

      Nscale promised Britain's largest AI supercomputer in Essex, 23,040 chips by early 2027. The grid says full power comes in the 2030s, and its only publicly announced customer, Microsoft, has walked.
