From Minutes to Seconds: LLM-Guided Autotuning for Helion Kernels

Helion’s LLM-guided autotuner achieves LFBO-level kernel performance while benchmarking about 10X fewer configurations in roughly 6.7X less wall-clock time. The approach is model-independent, working across Opus-4.8, gpt-5.5, and Sonnet-4.6.
