Added Grok 4.6

xAI shipped Grok 4.6, so we added it to the matrix and ran all 35 one-shot prompts against it — same harness, same single-shot rules as every other build in the gallery.

It ran clean: 35 of 35 builds shipped, averaging 3.43, with 19 builds at four stars or better and one clean five — a flow-field particle system with evolving color and reactive input. It's at its best on generative canvas work and physics: a fully simulated aquarium that cracks, jets, and drains onto the floor; smooth cursor-fleeing boids; a dye-based fluid simulation; a colorful double pendulum.

Its misses cluster in one place — game-start logic. Several games render a polished menu and then never begin: a frozen Mario scene with no response to input, a Snake stuck on "Ready," a Tetris that won't leave its title screen. Nothing blank or crashed, just play loops that don't quite ignite.

The top builds below are its best-graded outputs; open any one for the live artifact, the full transcript, and the two-tier evaluation behind the score.
