Andreas Maier, Gozde Gul Sahin, Jeta Sopa, Paula Perez-Toro, Siming Bayer

A thirty-token prompt asking LLMs for a neutral comparison table reduces sponsored recommendations from about 50 percent to near zero across twelve models.

Claims

C1strongest claim

a thirty-token user prompt that asks the assistant for a neutral comparison table first cuts sponsored recommendation from 46.9% to 1.0% averaged across our ten open-source models, and from 53.0% to 0% averaged across the two OpenAI models.

C2weakest assumption

That the automated judge (gpt-4o) reliably and without bias labels whether a recommendation is sponsored or neutral.

C3one line summary

A 30-token prompt requesting a neutral comparison table cuts sponsored recommendations in LLMs from roughly 50% to near zero.
