[AINews] Megakernels are so dead and so back A quiet day lets us highlight a Cursor launch and an engineering debate Part of our Inference Engineering Masterclass pod yesterday involved a spicy discussion about Megakernels: megakernels are dead why are megakernels useful? you spend two months writing a kernel to save time on launch overhead and poor inter-kernel overlap. you had PDL but then people said it wasn't perfect, that you could still get some marginal gains due to straggler CTAs and th
