Claude Writes Fused Megakernel 18x Faster Than PyTorch in 2.5 Hours
AccBalanced · x · 2026-07-03
An engineer shared a case where Claude spent roughly 2.5 hours writing a fused megakernel, achieving an execution speed over 18 times faster than the PyTorch baseline implementation. This result demonstrates AI's practical capabilities in writing low-level, high-performance computing code, already surpassing the short-term output of average engineers in specific engineering scenarios.
