Quantization
The export was produced with AutoRound 0.14.2. The settings below are taken directly from quantization_config.json and config.json:
- Weight precision: INT4
- Format: W4A16 (4-bit weights with floating-point activations)
- Group size: 128
- Symmetric quantization: enabled
- Packing format:
auto_round:auto_gptq
- Calibration sequence length: 512 tokens
- Batch size: 1
- Quantization method:
auto-round
- Quantization targets:
model.language_model.layers and mtp.layers
- Selected linear-attention input projections are retained at 16-bit through
extra_config
mtp.fc is retained at 16-bit through extra_config
The exported configuration reports BF16 as the model dtype. The repository is approximately 19.02 GB decimal (17.71 GiB), including configuration, tokenizer, processor files, and SafeTensors weights.
Model details
- Model name:
Huihui-Qwen3.8-27B-Abliterated-INT4-W4A16-AutoRound
- Architecture:
Qwen3_5ForConditionalGeneration
- Text layers: 64
- Hidden size: 5120
- Vocabulary size: 248,320
- Maximum position embeddings: 262,144
- Attention layout: 48 linear-attention layers and 16 full-attention layers
- Parameters represented by the indexed model weights: 6,284,446,960
- Vision tower: BF16, with
Qwen3_5ForConditionalGeneration multimodal processor configuration
The source model retains its first 15 layers without ablation and does not modify its MTP or visual components. That is source-model information; it is not an additional transformation performed by this AutoRound export.
Usage with vLLM
The following command launches this exact model repository with vLLM and exposes both the stable local alias and the full model name. The --served-model-name values are the names accepted by the OpenAI-compatible API; they do not rename the files on disk.
vllm serve letechlead/Huihui-Qwen3.8-27B-Abliterated-INT4-W4A16-AutoRound \
--served-model-name local Huihui-Qwen3.8-27B-Abliterated-INT4-W4A16-AutoRound \
--tensor-parallel-size 2 \
--max-model-len 262144 \
--port 18080
This command is for the exact artifact letechlead/Huihui-Qwen3.8-27B-Abliterated-INT4-W4A16-AutoRound; do not replace the model argument with a generic path such as /models. The tensor-parallel size, maximum context that is practical, and KV-cache dtype must be chosen for the available hardware. The model supports text input and multimodal processor inputs when the installed vLLM release supports this architecture and its AutoRound/AWQ-compatible INT4 format.
Use a recent Transformers release that supports Qwen3_5ForConditionalGeneration and the model's processor:
from transformers import AutoModelForMultimodalLM, AutoProcessor
model_id = "letechlead/Huihui-Qwen3.8-27B-Abliterated-INT4-W4A16-AutoRound"
processor = AutoProcessor.from_pretrained(model_id)
model = AutoModelForMultimodalLM.from_pretrained(
model_id,
device_map="auto",
dtype="auto",
)
For text-only requests, pass text through the processor. For image or video requests, pass the media together with the text prompt according to the Qwen3.5 Transformers documentation.

Limitations and responsible use
This model inherits the source model's abliterated behavior and may produce sensitive, controversial, or otherwise unsafe output. It is intended for research, evaluation, and controlled use. Users are responsible for complying with applicable laws, platform rules, and organizational policies, and for reviewing outputs before relying on them.
