The original post

Had jev, claude haiku 4.5, and gemini 3.5 flash-lite play tetris. Same 200 pieces, same legal moves, real time.

Jev: 9200 pts, 75 lines, 300ms/move, 0 errors

Claude: 8900 pts, 72 lines, 1.52s/move, 0 errors, $0.48

Gemini: 9000 pts, 75 lines, 1.13s/move, 0 errors, $0.02

Jev wins on score and is doing it 4-5x faster per move than either LLM, for basically free. That gap isn't the model being smarter, it is the model doing less work per decision
