Tested 3 models across 20 product categories: AI recommendations converge hard

deedydas · x · 2026-08-28

deedydas ran an experiment: AI systems tend to recommend the same thing when asked "what's the best product for X?" He tested 3 models across 20 product categories and 5 prompt styles (best, most popular, best value, splurge, and "what do I deserve?").

Models agree a lot — and the biggest surprise was a Hästens luxury mattress that costs $500k. Full artifact is shared.
