ARC-AGI — Frontier Reasoning, Playable
Frontier AIReasoningiOS
Real tasks from the ARC-AGI corpus, rendered in the app.
ARC-AGI is the benchmark the frontier labs chase — a set of visual reasoning puzzles that are trivial for humans and brutally hard for machines. We built a native app to make the whole corpus playable.
Every task is rendered as a crisp grid of colored cells. You can browse the training and evaluation sets, attempt the puzzles by hand, and see just how strange and beautiful the patterns become — concentric mandalas, symmetric mosaics, rules hiding in plain sight.
It is the kind of project we build for ourselves: a way to sit with the frontier of AI reasoning, hands-on, and understand it from the inside.
