Local GLM 5.3 Flash finishes the same coding task 4.2x faster than cloud (10:24 vs 43:48)

A Reddit user benchmarked GLM 5.3 Flash via Z.ai's official subscription vs served locally, running the same one-shot prompt through the same Zcode harness to build a Three.js farming game. Cloud took 43:48; local finished in 10:24—4.2x faster—with near-identical output (118K tokens each, slightly more input tokens locally). The takeaway: token savings ($0.70 here) aren't the real argument for local AI; the speed advantage means shipping several times more code per day.
