What Semantris actually is

Type a word and the machine ranks the blocks on screen by how closely each relates to what you wrote, then clears whichever it picks. There is no dictionary of correct answers, only associations the model has learned. Two modes, one arcade-paced and one that stacks blocks.

Why it is worth your time

Working out which sideways association the model will accept is the actual game, and it fails in ways that reveal how it thinks.
