I have to retract what I posted as the fastest speed of Qwen 3.8 Flash on a single DGX Spark. Cruz shipped a custom ExLlamaV3 fork and a native engine path. I ran the same model on the same Spark: 102.6 max, 80 tok/s on code, 70 tok/s on prose. My previous benchmark and community recipes was 48.6 tok/s. I ran my full grid on it so you don't have to. This might now be the best way to run this model, without breaking the bank on one DGX Spark. THE QUANT EXL3 at 3.05 bits per weight. Trellis coding packs information more efficiently than plain rounding, so 3 EXL3 bits should land near 4.5
