distribution

1..100 · normalized

How often this model picks each number from 1 to 100. A truly random generator would draw a flat 1% line across the chart (shown in cyan). Tall amber bars are the model's favourites — numbers that contain the digit “7” are highlighted because LLMs systematically over-pick them.

last digit bias

uniform = 10% each

The last digit (0..9) of every picked number. In a uniform 1–100 draw each digit would appear roughly 10% of the time. Most LLMs dramatically over-pick “7” and avoid 0 and 5.
