Nine ways to see a model think

Nine demos built to land in about nine seconds, with no background needed. Under them, two pages that build the biblical models for real, and fourteen short demos of the mathematics, every number computed from the 66 books.

01

How it learns to speak

The single move everything else is built on, what it costs, and how doing it at scale produces a model that can be pointed at many tasks. These three, and the six after them, are illustrations; their numbers are the demos' own, not measurements from the Bible model.

02

How you shape its behaviour

Three ways to steer a model after it can talk: keeping what works, nudging the odds, and building something that looks a lot like character.

03

How you see inside it, and why that matters

Two ways to read a model's half-finished thinking, and one demonstration of what goes wrong when nobody checks.

04

Build the models yourself

Everything above, built for real from one text: first with a hand-written lexicon, then with no lexicon and no labels at all.

05

The mathematics underneath, on one book

Fourteen nine-second demos, from vectors to a GPT trained from scratch on the Bible alone. Every number is computed from the 66 books or from that model; the few outside figures, such as hardware prices, are dated and linked.

F1Arrows of meaning

Gold and silver point the same way; gold and wicked do not. The Bible's own words as arrows, with the angle between any two exact.

Open →
F2One rule, every point

Four numbers move every point at once. Drag the two columns and watch the word cloud turn, stretch or shear with them.

Open →
F3Same points, new rulers

Turn the rulers and every coordinate changes, though nothing moved. A tilted cloud becomes simple in its own basis.

Open →
F4When a matrix forgets

Slide one column onto the other and the plane folds onto a line: different words land on the same point, and no undo exists.

Open →
F5Few patterns, many numbers

The 66 books' similarities to each other, 4,356 numbers, rebuild to 89% from two patterns and 92% from five.

Open →
F6Rotate, stretch, rotate

Every matrix is rotate, stretch, rotate. Keep the biggest stretches and you have the best compression of a 240-word by 66-book table.

Open →
F7Count, then divide

After "in", the next word is "the" 35% of the time, because that is how often it was. Spin the wheel and a sentence writes itself.

Open →
F8Surprise in bits

A word costs log₂(1/p) bits. Genesis 1:1 priced word by word, and why a better model is one that pays fewer bits.

Open →
F9Which way is up

Move over the hills and the arrow shows the steepest way up; step against it and you descend. Slopes multiply through a chain: backpropagation.

Open →
F10Roll downhill, carefully

Plain descent, momentum and Adam race down one valley; the learning rate decides who arrives. Beside them, the real loss curve of the Bible GPT.

Open →
F11A GPT grown from one book

Tokenizer, attention, MLPs and training loop written by hand, trained on nothing but the 66 books, and running in your tab. Type a prompt.

Open →
F12Where a head looks

Anthropic's framework: every head has a where (QK) and a what (OV). Watch the heads of a two-layer model on a verse, then test them for induction.

Open →
F13Reach in and change a thought

Switch off one head or one MLP and watch the next word change, on the real model, with the three lines of nnsight that do the same.

Open →
F14Hours and dollars

Pick a model size and a number of passes over the Bible; see the hours and dollars on RunPod and Vast.ai, dated, then the commands that run it.

Feature space and J-Space

Reading a model through its features rather than its words.
