| Qwen3.8 27B | AWQ + DSpark | SGLang TP2, 1 stream | 69.9 | not stated | ⚡ spec-decode (DSpark)📏 Single-stream prose decode as published in Tech2wild's recipe README (0xSero's SGLang recipe). |
Numbers by Tech2wild (tonyd2wild); 0xSero's SGLang recipe. RigBase read the GitHub README on 2026-10-28 and checked each figure against the text. RigBase did not re-run it. Speculative decoding (MTP/DFlash/DSpark) inflates predictable text; these rows prefer prose/code over counting peaks. Recipe has no LICENSE file; RigBase cites the published numbers and links the README only (no copied code or config blocks).
