Why would a model called "Fast" not advertise the tokens per second speed it performs at? Is "Fast" not representing speed, but another meaning? Is it too variable?

They sound like they’re positioning it more that it’s faster to complete because it uses fewer tokens - see the mentions of token efficiency.
