Helion tops B200 kernel hackathon
A developer won PyTorch's inaugural Helion Hackathon (March 2026) by topping the leaderboard for causal depthwise 1D convolution on B200 GPUs, hitting ~10 microseconds. Helion's autotuner handled 90–95% of the optimization automatically by compiling a single kernel definition into thousands of Triton configurations.
// ANALYSIS
The result is a concrete proof point for Helion's core claim: serious GPU kernel performance is reachable without being a Triton or CUDA expert, just a PyTorch programmer who understands tiling.
- –Helion's autotuner systematically explores block sizes, loop orderings, and memory layouts — a search space that explodes combinatorially on B200 hardware
- –B200 kernel optimization is brutal: Gated DeltaNet patterns, Mixture of Experts, inter/intra-chunk attention, and KV caching each demand different strategies per model architecture
- –The last 5–10% still required manual grinding — Helion compresses the hard work dramatically but doesn't eliminate expertise entirely
- –Local inference via NVIDIA Pro 6000 powering an agent harness performed well throughout, reinforcing that local LLM setups are viable for competitive development workflows
- –Hackathon submission repo published at github.com/brandonin/helion-hackathon-submission, useful as a reference for anyone exploring Helion on convolution kernels
