Agents spent 2.5 weeks and ~$600 in tokens to rewrite PDAL in CUDA, 2.5-14x faster
ctjlewis · x · 2026-09-25
A developer let coding agents run nonstop for 2.5 weeks ($600 in tokens) to fully rewrite PDAL with CUDA kernels plus CPU-side optimizations, making point cloud pipelines 2.5x to 14x faster. The result is free and open source for citizen cartography—a concrete case of agents completing a real high-performance engineering rewrite.
