Explainer tools · feel lab 02

Teaching tools, three rooms.

Two feels each for three new explainer tools. Room 1 quizzes you on real o200k merges before they happen. Room 2 makes the softmax equation tactile. Room 3 lets you wander a story tree and backtrack instantly. Everything here is a candidate — tap around and pick what feels right.

Room 1

Predict, then reveal

The step-through animator, but it asks what merges next before showing it. Real o200k merges — traced with the byte-identical from-scratch tokenizer, never invented.

Room 2

Live equation

Softmax with its guts showing — change the temperature or the logits and watch every probability move. Illustrative logits: hand-written mock numbers for feel-testing, not a real model.

Room 3

Branch explorer

One prompt, many paths. Descend the tree, tap any ancestor to backtrack instantly, compare endings. Illustrative story tree — hand-written, not generated.
