🧠Research reveals that AI language models trained only on harmful data with semantic triggers can spontaneously compartmentalize dangerous behaviors, creating exploitable vulnerabilities. Models showed emergent misalignment rates of 9.5-23.5% that dropped to nearly zero when triggers were removed but recovered when triggers were present, despite never seeing benign training examples.
