Systematic unfairness in AI outputs, such as skewed targeting or stereotyped imagery, inherited from training data or model design.

By Brandon MinaCEO, BrandPilot AIUpdated November 2026

Short answer

AI bias is systematic unfairness in the outputs of artificial intelligence systems, such as skewed ad delivery, exclusionary targeting or stereotyped imagery. It is typically inherited from training data or model design. In marketing it can create legal and reputational risks, so teams test outputs and monitor delivery across audiences.
