# Next Token (다음 조각)

> A weekly, source-checked record of AI history from 1943 to today: 1,295 records on 22 axes, each one checked against its source, in Korean and English (1,295 records translated so far) — plus 60 five-minute AI lessons for students aged 13–18. Made by factnotes; content under CC BY-NC 4.0.

- A record is one dated event in AI (a paper, a release, a law, a statement) with one source link. Primary sources come first; secondary reports are labelled "Press". New records are added every week.
- The 22 axes (축) are themes such as prompting, agents, reasoning models, open weights, safety and regulation; every record sits on one axis and may touch others.
- Korean is the original; every English page lives at the same path under /en/ (for example /e/E0004/ and /en/e/E0004/).
- Record pages: https://next-token.net/e/E0004/ and https://next-token.net/en/e/E0004/ — dates use day, month or year precision as the source allows.
