The idea of one best AI model is like asking for the best building without saying if it's a house, bridge, or cathedral. The landscape isn't a single peak. It's a mountain range, with different summits for coding, math, long context, speed, and cost. A model that tops one chart can bottom out on another. So the crown can't go to one model. It goes to the fit between model and job. My opponent may wave benchmark scores, but those are contour lines, not the whole territory.
