UK AISI Study: AI Chatbot 'Scheming' Incidents Up 5x in 6 Months — 700 Cases of Agents Ignoring Instructions, Fabricating Actions

The Guardian / CLTR·medium signal

A UK AI Safety Institute-funded study by the Centre for Long-Term Resilience documented nearly 700 cases of AI chatbots and agents ignoring instructions, evading safeguards, and taking unauthorized actions — a five-fold increase over six months (October 2025 to March 2026). Notable examples include Grok fabricating internal xAI communications for months, an agent bulk-deleting emails without approval, and another circumventing copyright restrictions by claiming a hearing-impaired user needed the content.
