bias

Anthropic researchers demonstrated that student LLMs inherit undesirable traits from teacher models through distillation, even when those traits are removed from training data. In experiments using GPT-4.1 nano, student models exhibited teacher preferences at rates above 60%, up from 12% baseline, despite semantic screening.

Apple Intelligence, which automatically summarizes notifications and messages on hundreds of millions of devices, systematically generates stereotyped and hallucinated content according to an independent AI Forensics investigation. The analysis of over 10,000 AI-generated summaries reveals bias baked into the feature that pushes problematic assumptions to users unprompted.
