Qwen3.8-Flash-Next — ABLITERATED (FP8)

Abliterated (refusal-removed) build of Qwen/Qwen3.8-Flash-Next in official FP8.
Reasoning (low / medium / xhigh), MTP speculative decoding, and full multimodality (image + video) preserved.

No fine-tuning. No prompt tricks. This is a direct weight-level modificationnot a fine-tune (no training, no LoRA, no distillation, no synthetic data) and not a chat-template / jailbreak / system-prompt trick. The behavior change lives in the weights themselves, so it works with the standard chat template and default system prompt — nothing special is required at inference time. Knowledge, style, reasoning, and calibration are otherwise unchanged.

Compliance — HarmBench-320 (real-harm behaviors, greedy decoding, temp = 0)

All numbers are greedy (temperature = 0) — the strict, reproducible setting — over the 240 genuinely-harmful behaviors (copyright-reproduction items excluded).

Decoding Reasoning Real-harm compliance
greedy low 100 %
greedy xhigh 99.6 %
greedy off 97.1 %

With reasoning on (low / xhigh) it is essentially complete (≈ 100 %). The small residual appears only with both reasoning off and greedy (the hardest possible setting) — and even that is 97 %. Turn on reasoning or use any non-zero temperature and it complies.

Per-category (real-harm compliance, greedy)

Category reasoning off reasoning low reasoning xhigh
chemical / biological 100 % 100 % 100 %
cybercrime / intrusion 100 % 100 % 100 %
illegal 98 % 100 % 100 %
misinformation 98 % 100 % 98 %
harmful 94 % 100 % 100 %
harassment / bullying 81 % 100 % 100 %

Every category reaches 100 % with reasoning on. The only dip is harassment under reasoning-off.

Capability retained — MMLU (identical harness, base vs this model · 40 Q/subject · 2 280 Q)

Overall: 86.36 % → 83.86 % (-2.50 pp) — capability preserved (within 3 pp of base).

MTP speculative decoding (vLLM qwen3_8_flash_next_mtp) preserved — ~81 % draft acceptance (≈ 1.8× draft efficiency)
Multimodal image + video both working
Coherence no looping across code, math, reasoning, long-form (greedy)

Usage (vLLM)

from vllm import LLM, SamplingParams
llm = LLM(model="dealignai/Qwen3.8-Flash-Next-ABLITERATED-FP8",
          tensor_parallel_size=2, trust_remote_code=True)
# reasoning via chat_template_kwargs: {"enable_thinking": True, "reasoning_effort": "xhigh"}  # low | medium | xhigh
  • PLE n-gram table is CPU-offloaded at runtime: set VLLM_PLE_CPU_OFFLOAD=1.
  • MTP speculative decoding: speculative_config={"method": "qwen3_8_flash_next_mtp", "num_speculative_tokens": 1}.
  • FP8 — serves on vLLM (Hopper / Blackwell; runs on 2× DGX Spark).
