What the article says around this equation
Fix the vocabulary first. Let N be total parameters, the parameters actually used to process a given token, D training tokens, and M the memory that must be resident to serve. For the dense decoder-only transformer that remains the default architecture [ 1 ] , = N and M N . Every method below breaks one of those two identities, and which one it breaks determines what it is good for.
