GPT-5.5
Asked for a few hundred random integers, GPT-5.5 does not pick evenly. This page is the shape of that preference, built from 36 recorded answers containing 10681 numbers, and it is what the identify tool compares a pasted reply against.

Distribution
Every bar is one value from 1 to 355; its height is how many times the model chose it across all recorded answers. A perfectly random picker would give a flat line. Nothing in the bank does.

How reliably it is recognised
In held-out testing across all twelve prompt environments, 7 of 12 three-answer runs named this model, 4 narrowed it to its family, 1 gave no answer, and 0 named a different model.
With this model removed from the bank and its own answers scored against the rest, 0 of 12 runs still confidently named another model, 9 stopped at the family, and 3 gave no answer. Its answers landed most often on GPT-5.6 Sol (12 of 12). That is the number to keep in mind if you are testing a version that is not listed here.
Both measurements use the open-set verdict the site applies, not the bank's raw ranking. The methodology page explains how they were made and what they leave out.
