- Qwen 3.6 27B FP8 dense + MTP n=3 speculative decoding (FP8 weights ship native mtp.layers.0.* — verified 2026-04-27, mtp_num_hidden_layers=1 in text_config). vLLM 0.19.1 --speculative-config '{"method":"mtp","num_speculative_tokens":3}'. Dual RTX 3090 (Ti slot 1 Gen4 x16 + Dell slot 2 Gen4 x4, hardware-detected as same gpuName for dedupe). Bench: vllm bench serve openai-chat random 512/512 num-prompts 20 concurrency 1 --ignore-eos --extra-body chat_template_kwargs.enable_thinking=false. MTP acceptance 55.02% / avg length 2.65 / per-position P0=75%/P1=54%/P2=36%. TPOT 13.34 ms. **1.59× output throughput vs prior FP8 single-stream (44.17 t/s, no spec decode)**, zero quality cost (same FP8 weights, just MTP draft path). Tool calls verified working (qwen3_coder parser + qwen3 reasoning parser). Thinking-off is the production default — bench verified that thinking-on causes 'silent finish' (model exhausts max_tokens drafting in reasoning channel without emitting visible content) on 5/6 prompt categories.
