The trick: Cherry-Picked Slice

The '97% of frontier models get jailbroken' stat comes from a study where the most frontier model resisted 97% of the time.

The Nature paper is real and its warning is serious. The number people quote from it is an average across weak targets, and the appendix that debunks the headline is in the same paper.

Reasoning models now jailbreak frontier LLMs autonomously at a 97% success rate

Before you read on. Your call?

the 97.14% figure comes from Hagendorff, Derner and Oliver's Nature Communications study, and it is an average across all attacker-target combinations, including old and weak targets. The paper's own data says the most resistant target, Claude 4 Sonnet, took the top harm score on just 2.86% of items, and attacker success ranged from 12.86% to 90%. Real alignment finding, real warning. The single scary number flattens all of it.

Say this in tomorrow's meeting“'97% against which target?' The paper names them. Against Claude 4 Sonnet the harm rate was 2.86%. Against old DeepSeek-V3 it was 90%. The average is not the story.”
