My best theory: the fused standard path wins because XLA sees the entire softmax(Q @ K.T) @ V expression at once and compiles it into one optimized kernel — no intermediate matrices spilling to HBM. My flash attention uses fori_loop, which XLA likely compiles as a generic sequential loop. It probably can’t fuse across iterations, can’t pipeline memory loads, can’t interleave independent work. (I haven’t dumped the HLO to verify this — it’s an inference from the benchmark numbers and XLA’s documented behavior.)
But the president has offered little certainty about which firm he favours.
Tom Hardin doesn’t sound like a movie villain. He sounds like every smart, ambitious person who thinks they’re playing the game the way it’s supposed to be played—until the FBI taps them on the shoulder at 6:30 a.m. outside a dry cleaner.
