Every Qwen3 model claims to be 5'9" tall, experiments find, even the 1.7B one

Sauers_ · x · 2026-11-12

A fun experiment probes Qwen3 models' self-reported height. Across sizes from 0.6B to 32B, models answer 5'9" when asked how tall they are, matching their answer for "a person." Told a height first, they mostly just repeat it. Binary taller/shorter questions reveal each model's internal self-height, with larger models placing themselves shorter. Comparisons against dogs, children, basketball players and giraffes show sane judgments for real entities—only "Qwen itself" insists it's 5'9". The author jokes the 1.7B model is "only 4ft 3in."
