About

Inception's Mercury 2.5 Preview is not an autoregressive model: a diffusion process refines whole blocks of tokens at once, which is how it answers at four figures of tokens per second for $0.04/$0.15 per M. The question this page asks is whether a model that writes sideways instead of downhill can still put the stop sign in line one. At preview pricing, it is the cheapest way to find out.
