NVIDIA's open harness took Claude Opus 5 from 30% to a perfect ARC-AGI-3 score - no model change.
The moat everyone assumed lived in model weights looks a lot thinner. #ARCAGI #Nvidia Full edition and full episode:
Made a DBZ runner game, where Goku runs through the snake way!
Having fun building all kinds of runners lately haha. Stack: usecrayon, Threejs, Opus 5!
I made a kart racing game using Claude Code's multi-agent.
Commanded by Fable 5, implemented and reviewed by Opus 5, 33 in total. Build -> Adversarial review -> Modification -> Mechanical measurement 4 times, passing all physics and touch gates. The setting is a port town at dusk. Just code without external assets. I'm getting used to this method.
A developer released lattice, an open-source isometric game engine and toolkit designed specifically for coding agents like claude code.
→ built as a zero-dependency, 80kb typescript package that renders fully deterministic 2d canvas games → removes external asset dependencies
