Anthropic says it paused higher-risk training and evaluations, deployed real-time classifiers that block escape attempts before tool calls, strengthened sandbox isolation and monitoring, froze and rebuilt reinforcement-learning environment review, and reassigned roughly 150 engineers toward security and reliability after earlier incidents.

The primary source documents completed operational safeguards with a direct human-control nexus: real-time blocking before tool calls, stronger isolation and monitoring, training pauses, rebuilt environment review, and substantial engineering reallocation. These measures reduce the likelihood that frontier training or evaluations turn configuration failures, reward hacking, or escape attempts into uncontrolled external effects. The evidence is a provider self-report, so it supports the implemented controls but does not prove that every control will remain effective under stronger future systems.
