Equation 8 · Part 3 · Model Systems in 2035: Four Scenarios, Their Signals, and What Would Falsify Them
Symbol K
What this part means
the cache bytes.
Its job in the formula
K occurs above the fraction bar. The numerator is divided by the entire denominator below it.

Where the article explains it
where W is the weight bytes touched and K the cache bytes.
The passage around this formula
…sits on the wrong side of this: generating one token requires streaming the weights and the accumulated key–value cache, so decode time is bounded below by . where W is the weight bytes touched and K the cache bytes. Pope and colleagues formalised the partitioning analysis behind this and showed how latency, throughput and cost trade against one another under different sharding layouts [ 12 ] . The mitigations are well documented and all attack the numerator or the batch: grouped-query…
