PyTorch adds compile-time heuristics for Helion kernels

PyTorch developers have introduced compile-time heuristics for Helion kernels that analyze intermediate representation and dataflow to select fast settings without slow autotuning. The system classifies kernels into matmul, reduction, or pointwise families, achieving performance competitive with handwritten libraries like Flash Linear Attention and vLLM operators while requiring negligible compilation time.
