“Fable achieved an 18.71X speedup vs. an optimized PyTorch baseline, compared to 14.4X (Claude Opus 4.8) and 4.34X (GPT 5.5) — and did so with a single cooperative kernel launch per decoded token, vs. 4–14 launches for all other high-scoring entries.”

“"The first genuine (and fastest) megakernel ever submitted to KernelBench-Mega, according to one of the benchmarks maintainers."”
