价值前沿

所有模型，按价格与能力作图。那条阶梯线就是前沿：没有模型能在两个维度上同时胜过它们。位于其下方和右侧的一切都是严格更差的选择——总有既更聪明又更便宜的东西。

Changing the workload below moves the frontier less than you would expect: 91% of frontier models are on it under every workload (only Solar Pro 4 moves). What does change is the price — the same model swings up to 4× across these shapes. So the control is not about which models to consider. It is about what you would actually pay for them.
