FastKernels: 46-Architecture Benchmark Exposes GPU Kernel Agent Failures in Production
May 21, 2026
Existing GPU kernel generation benchmarks mislead LLM agents by evaluating on single GPUs with synthetic inputs, ignoring compilation stacks; FastKernels introduces 46 representative architectures across 8 categories to test production-realistic integration.

HOW THIS AFFECTS YOU
●
builderYou can use FastKernels to evaluate whether LLM-generated GPU kernels will actually work in your inference stack, not just in sandboxes.
●
researcherWorth watching because it exposes a systematic reward-signal misalignment in kernel generation benchmarks, with a concrete 46-architecture replacement covering 8 categories.
