China's Floatboat Harness Beats Claude Opus 4.8 on All Five Benchmarks While Running on the Cheapest Model on the Market

AOE Tech Labs' Floatboat team ran a single-variable Harness benchmark experiment on August 7. With DeepSeek-V4-Flash as the model base and only the execution Harness swapped, the same 0.14-dollar model went from losing all five benchmarks against Opus 4.8 on DeepSeek's own Harness to winning all five on Floatboat's Harness, at 57.1 times lower cost.
