Act 01 · Text becomes numbers 2:30 The famous AI fails are all one bug

Why the AI thinks 9.11 > 9.9.

Two honest mechanisms collide: digit-chunk tokenization plus training-data neighborhoods where 9.11 genuinely "comes after" 9.9 (versions, chapters, dates).

Key ideas

  • The one idea — Two honest mechanisms collide: digit-chunk tokenization plus training-data neighborhoods where 9.11 genuinely "comes after" 9.9 (versions, chapters, dates).
  • How it is shown — The flip: rephrase as explicit decimal math (or ask for the subtraction) and the answer often corrects — same weights, different neighborhood.
  • The trap to avoid — Gotcha-benchmarking — one riddle, pass or fail, treated as an IQ verdict.
  • What it sets up — Compensation is engineering you can't see.

The AI saying 9.11 is bigger than 9.9 isn't a glitch. In software versions, book chapters, and dates, 9.11 genuinely comes after 9.9. The machine learned from that text.

The one idea

Two honest mechanisms collide: digit-chunk tokenization plus training-data neighborhoods where 9.11 genuinely "comes after" 9.9 (versions, chapters, dates).

Ask which is bigger: nine point nine, or nine point eleven. Watch a machine that passes graduate exams flunk third grade. The infamous answer — "9.11 is bigger" — isn't a glitch. It's two honest mechanisms colliding. And you now own both of them. Force one: the chop. "Nine point one one" doesn't arrive as a quantity. It arrives as chunks — perhaps a nine, a dot, an eleven — and the model has no number line inside. Only text statistics about how digit-chunks behave. And eleven, as text, outranks nine.

How it works — the demo

The flip: rephrase as explicit decimal math (or ask for the subtraction) and the answer often corrects — same weights, different neighborhood.

Force two: the training data votes. Where does 9.11 live in text? Software versions — where it genuinely comes after 9.9. Book sections. Dates. In most of the text it learned from, nine-eleven really is later, higher, newer. The likeliest continuation follows the neighborhoods it knows. Here's the proof it's representation, not ability. Rephrase: "as decimal numbers, which is greater?" Or make it subtract them first. The answer often flips to correct.

The trap to avoid

Gotcha-benchmarking — one riddle, pass or fail, treated as an IQ verdict.

Why it matters — and what’s next

Compensation is engineering you can't see.

Same weights — the framing pulled the math neighborhood instead of the version-number neighborhood. The trap: the gotcha reflex. "It failed my riddle, so it's dumb" — and its twin, "it aced my riddle, so it's smart" — both misread one sample of dice. What you actually learned is sharper: how a question is tokenized and phrased selects which patterns answer it. That's a lever you now hold. Newer models mostly pass this now — more math data, reasoning training, or quietly calling a calculator tool. The blindness didn't vanish; it got compensated. Know the difference: compensation is engineering you can't see — and shouldn't blindly count on. One more tokenization crime scene to visit: a single invisible space that breaks working code. Then we finally leave the chopper — and meet meaning itself.

One phrase flips the famous 9.11 fail: ask 'as decimal numbers, which is greater?' and the answer often corrects. Same model, same weights — the framing picked the neighborhood.
