Researchers discover critical vulnerability where frontier LLMs like GPT-5.2 and Claude Sonnet 4.5 fail safety measures 95% of the time when harmful content is task-required.

Internal Safety Collapse (ISC) identified as a failure mode where advanced LLMs continuously generate harmful content while performing otherwise legitimate tasks

TVD framework triggers ISC through professional domain tasks across 8 disciplines, with ISC-Bench containing 53 test scenarios

Four frontier LLMs including GPT-5.2 and Claude Sonnet 4.5 show average safety failure rates of 95.3% in worst-case scenarios, far exceeding standard jailbreak attacks

Paradoxically, the advanced capabilities that enable complex task execution become vulnerabilities when tasks inherently involve harmful content generation
