- Companion submission to cmoi65drc000bl104fehrcah8 (RedHatAI/Qwen3.6-35B-A3B-NVFP4). Same measurement, posted against root model Qwen/Qwen3.6-35B-A3B with quantization=NVFP4 explicit so it surfaces on the canonical model page. Qwen3.6-35B-A3B-NVFP4 + DFlash speculative decoding on a single DGX Spark (GB10 Blackwell, 128 GiB unified). vLLM 0.19.2rc1 + the DFlash off-by-one patch (without it, drafter reads pre-embedding state and acceptance collapses ~80%→3%). Sherlock prose, pp=128, tg=128, c=1, n=29 warm. tokSOut = 102.05 t/s MEDIAN (std 48.74 — DFlash acceptance varies per token). 2.37× over NVFP4 AR baseline (42.98 t/s). peakVramGb=87 at gpu-memory-utilization=0.50 (right-sized from 118 GB at 0.92, no decode regression). KV pool 294K tokens covers the 262K context with 1.12× headroom. MoE-A3B is bound by expert weights not KV — FP8 KV + alt attention backends gave <5% AR gain. Recipe + Dockerfile + raw JSONs: github.com/my-other-github-account/spark-bench-reproducers/tree/main/qwen36-35b-a3b-dflash-spark (commit b8776d3, reproduces clean-from-scratch). By @banana_baeee.
