Hugging Face docs update: Shipping Triton autotune configurations

RisingSayak · x · 2026-08-19

JIT kernels compile and autotune on first invocation to select the fastest configuration for the specific hardware and problem shape. However, autotuning adds runtime overhead.

Hugging Face Kernels now clearly supports packaging pre-tuned configurations with the kernel. By storing the best configurations as JSON files, the kernel can look them up at runtime, reducing costly tuning time. This approach is used, for example, in vLLM's fused MoE kernel.
