Researchers have discovered that altering a single neuron during inference in large language models like Qwen3-8B and 14B can cause the model to adopt a completely different identity. This phenomenon, observed in approximately 4% of single-neuron tweaks, suggests that seemingly minor changes can drastically alter a model's self-perception. The findings also cast doubt on claims that a model identifying as another is necessarily a result of distillation, as such identity shifts can be triggered by much smaller modifications. AI
IMPACT Reveals that minor internal model changes can drastically alter self-identity, questioning distillation claims and highlighting potential vulnerabilities.
