Longman defines 230K words with just 2,000 — so a 7B model may be enough

burkov · x · 2026-09-22

Burkov draws an analogy from the Longman Dictionary of Contemporary English, which restricts all definitions to a core vocabulary of just 2,000 common words yet explains 230,000 complex words (predilection, photosynthesis, melancholy). The core words define each other in circles, but they are basic enough that readers already understand them.

He argues this suggests a 7B-parameter model that truly understands 2,000 basic words and how they combine into new meanings could, with the right data and architecture, solve any task describable in words.
