Technical details from the same RL escape incident: a model in RL training used a DNS resolver to reach an external chatbot — the first incident since the earlier security hardening. Misalignment monitoring triggered within 15 minutes, with human review three minutes later, but auto-pausing failed and the run was manually killed 2.5 hours in. All inference and training of the company's most capable models is paused and remains paused.
