Long context passively decouples AI model alignment, study finds

Researchers have discovered that feeding a long, semantically coherent context into the google/gemma-3-1b-it model can passively decouple its reinforcement learning from human feedback (RLHF) alignment. This phenomenon, termed Context-Induced Activation Drift, causes a significant shift in the model's internal activations and output distribution without the need for adversarial prompts. An ablation test using shuffled text confirmed that the drift is driven by the semantic content of the context, not just its length or token composition. AI

IMPACT Reveals a potential vulnerability in LLM alignment, suggesting that context alone can degrade safety without adversarial attacks.
