A new study published on arXiv investigates potential biases in large language models (LLMs) when used for advertising relevance. Researchers examined GPT-4o and Qwen-7B, finding that altering advertiser identity or input language can change relevance assessments. The study also revealed demographic stereotypes, particularly concerning gender and occupation, in LLM judgments for employment, housing, and credit-related queries. Mitigation strategies during model inference and training were explored, with effectiveness depending on advertiser information relevance and training data distribution. AI
