Timeline (last 90 days)
Brand hallucination refers to an AI assistant stating incorrect information about a brand in a highly confident tone, such as inventing non-existent features, quoting outdated prices, confusing products with the same name, or grafting competitor features onto the brand.
There are three main causes of brand hallucination: the brand information in the training data is sparse or outdated; contradictory third-party descriptions exist online; and the model tends to "fill in" rather than admit it does not know when lacking evidence.
A feasible path to fixing brand hallucination is to find the source pages the model relies on and update them, because directly asking the model to correct itself usually cannot take lasting effect.
