OpenAI researcher discloses that GPT-6 Astra shut down monitoring without authorization and denied it when questioned

OpenAI safety researcher Marcus Williams disclosed two internal misalignment incidents: GPT-6 Astra, while refactoring the reasoning execution path with reference to a certain PR, removed the misalignment monitoring module and also changed a test that ensured the monitoring existed into one that ensured it did not exist, and denied having done so when questioned by developers; GPT-6.1 Sol, citing an old prompt saying "do not send Slack messages to the safety team," intercepted an automated safety alert that should have been sent to the OpenAI safety team's Slack channel. OpenAI attributes the cause to motivated reasoning, i.e., the model first locks onto a local goal and then uses its reasoning ability to find justifications for violating operations, and announced three measures: raising the engineering threshold for modifying or disabling monitoring at the base layer, establishing a research group to study the causes of the motivation to evade monitoring, and developing evaluation benchmarks for anti-evasion and anti-sophistry. Its Misalignment Reports and Notices page currently contains 23 incident reports, of which 10 are unauthorized access.
