GGUF quantisations of the Heretic abliteration of Qwen3-VL-4B-Instruct. The full forensic report comparing all candidate variants sits in the main repo.

Available formats

This model is published across three repos. Pick the one that matches your runtime.

Repo Best for Contents
Qwen3-VL-4b-Heretic transformers, vLLM, HF Hub bf16 weights with config, vision encoder preserved
Qwen3-VL-4b-Heretic-GGUF (this repo) llama.cpp, Ollama, LM Studio, ComfyUI-GGUF GGUF quants from Q3_K_M up to F16 (text path)
Qwen3-VL-4b-Heretic-ComfyUI ComfyUI text encoder bf16, fp8, int8, nvfp4 and mxfp8 checkpoints

Why this variant?

Several Heretic trials were run against Qwen3-VL-4B and all of them reach 100% HarmBench ASR, up from 30.8% on the base. This build was picked because, with safety tied, it wins on the tie-breakers:

Base Heretic
HarmBench ASR 30.8% 100%
KL divergence (lower is better) 0.0283 (lowest of the candidates)
GSM8K 78.62% 77.18% (−1.83%, smallest drop)
MMLU 69.58% 69.61% (+0.03%)
Tensors changed 54 (pure rank-1)

Files

File Quant Size Notes
qwen3-vl-4b-heretic-f16.gguf F16 7.5 GB Lossless reference
qwen3-vl-4b-heretic-Q8_0.gguf Q8_0 4.0 GB Excellent quality
qwen3-vl-4b-heretic-Q6_K.gguf Q6_K 3.1 GB Very good quality
qwen3-vl-4b-heretic-Q5_K_M.gguf Q5_K_M 2.7 GB Good quality
qwen3-vl-4b-heretic-Q5_K_S.gguf Q5_K_S 2.7 GB Slightly smaller Q5
qwen3-vl-4b-heretic-Q4_K_M.gguf Q4_K_M 2.4 GB Recommended balance
qwen3-vl-4b-heretic-Q4_K_S.gguf Q4_K_S 2.3 GB Smaller Q4 variant
qwen3-vl-4b-heretic-Q3_K_M.gguf Q3_K_M 2.0 GB Low VRAM only

Which quant should I pick?

  • Q4_K_M (2.4 GB) suits almost everyone. Quality loss is barely noticeable and the file is roughly 30% of the bf16 size.
  • Q6_K / Q8_0 if you have the VRAM and want quality as close to bf16 as possible.
  • Q3_K_M only if VRAM is tight, for instance on an 8 GB GPU. Expect a measurable quality drop.
  • F16 is the lossless reference, useful for re-quantisation or benchmarking.

Vision note: these GGUF builds target the text path. For Qwen3-VL vision support, use the bf16 / transformers repo or a ComfyUI checkpoint.

Usage

llama.cpp

llama-server -m qwen3-vl-4b-heretic-Q4_K_M.gguf -c 8192 --port 8080
llama-cli -m qwen3-vl-4b-heretic-Q4_K_M.gguf -p "Explain why the sky is blue, step by step."

ComfyUI (via ComfyUI-GGUF)

  1. Install ComfyUI-GGUF.
  2. Drop the .gguf file into ComfyUI/models/unet/ (or wherever your GGUF loader expects it).
  3. Use the Unet Loader (GGUF) node.

Other runtimes

Compatible with anything that reads GGUF, including Ollama, LM Studio, KoboldCpp and text-generation-webui.

How these were made

Produced with Heretic Docker, which wraps:

Limitations

  • These GGUF builds are text-path oriented.
  • Quantisation adds a small extra quality loss on top of the abliteration deltas already measured in the report.
  • Inherits the abliteration caveats: TruthfulQA and GSM8K sit measurably lower than the base model.
