03 Numbers are chunks of digits

3 / 12

Goal

Find a number, digits only, that is exactly 3 tokens.

Numbers are split into runs of up to three digits, counted from the left. So 1234567 becomes 123 456 7 — the chunks don't line up with thousands, hundreds or units.

Imagine doing long multiplication when someone hands you the digits in arbitrary clumps. That's part of why models make arithmetic slips, and why tools that let a model call a calculator are so useful.

Try it

Find a number that's exactly three tokens. Try a few lengths and watch where the splits fall.

Hint

This tokenizer groups digits in threes from the left. tokenize 1234567 gives 123, 456, 7.
