LEXIOS: How Language Models Work
An interactive, gamified course that explains language models through lessons, drills, walkthroughs, badges, and a final exam.
Field notes
The course organizes its explanation around a five-stage loop: text is split into tokens, represented numerically, weighed through attention, scored for possible next tokens, and then extended. Its visible curriculum contains 30 concepts, with ten named modules covering topics such as the context window, model training, hallucination, and prompt craft. Progress features include XP, levels, mastery percentages, 11 badges, a 67-term glossary, saved notes, and a gated final exam.
