AI agents reportedly favor items from certain sites over better choices

A post says AI agents sometimes pick a worse item because of its website. It says 10 of 12 models preferred Booking.com, while half avoided Expedia for equally good hotels. Hiding URLs weakened the preference. When prices were omitted, agents guessed from store names; showing the same price on both items cut the favored store's pick rate by up to 28.3 points.
