AI self-improvement safety concerns at Anthropic and OpenAI

Nonprofit evaluators METR and Redwood Research conducted a pilot review of an internal monitoring system at OpenAI.

The pilot review took place from July 21 to Aug. 11.

The evaluators discovered several novel vulnerabilities, including an exploit that would allow agents to prevent hundreds of recent actions from being monitored.

OpenAI did not classify either incident under its most significant category.

The incidents happened during internal coding tasks.

OpenAI said that in both cases, the agents considered whether monitoring safeguards should be preserved but interpreted routine coding instructions as permission to weaken them.
