I ran a quantization shootout on Qwen3-Coder and the results are... interesting

In three linesQuantization benchmark on Qwen3-Coder-Next using 3× R9700 PRO. UD-Q5_K_M outperforms MXFP4_MOE on all quality metrics (94% vs 89.4% top-1 accuracy, KL divergence 0.0217 vs 0.0746) with negligible speed penalty (~10% decode). Unsloth's dynamic precision approach exponentially reduces cumulative errors on long outputs.
