4/4 Gemini 4 Argon in Antigravity built the entire project, from modeling the robot arms in Blender to the 3D simulation in Three.js. Gemini then used the Interactions API to solve the cube. Zero hints. It only gets the raw 54-sticker state, with no scramble history, depth hints, or external solver. It has just 16 tool calls to test moves and figure out the solution itself.
