User umeshai crafted a tricky prompt: list exactly 100 distinct, real, visually identifiable objects whose English names begin with X—no "Xmas" substitutes, no padding by attaching ordinary nouns to base words. He later shared the model's self-review score of the attempt. With so few genuine X-words, it doubles as a playful hallucination stress test.
