- Official NVIDIA NVFP4 quant of Qwen3.6-27B (modelopt v0.45 MIXED_PRECISION: MLP W4A16_NVFP4, attention FP8, calibrated FP8 KV). vLLM 0.24.0, single-stream (max-num-seqs=1), no spec-decode, max-model-len 148000. Median of 3 (2 warmups), 163-tok prompt / 512 out, client-observed HTTP timing. On consumer Blackwell sm_120 the W4A16 MLP rides the Marlin dequant path (no native FP4 GEMM for weight-only 4-bit). Display attached to the 5090 (~10% pstate cost). tokSOut=decode throughput.
