Qwen3.6-27B-4.5b-mlx-AutoRound

Model Details

This model is an mlx format 4.5b mixed model with group_size 128 and symmetric quantization of Qwen/Qwen3.6-27B generated by intel/auto-round. Please follow the license of the original model.

We currently support this format in AutoRound, but do not have the hardware to validate this large model.

As a result, we are unable to verify whether it runs correctly or achieves expected performance.

We would greatly appreciate your help in testing it, and welcome any contributions to our open-source project.

This model currently has some issues, as discussed in ml-explore/mlx-lm#1214. For now, we recommend using AutoRound to generate uniform-bit models instead.

MLX-VLM inference

from mlx_vlm import generate, load
from mlx_vlm.prompt_utils import apply_chat_template
from mlx_vlm.utils import load_config

model_name_or_path= "Intel/Qwen3.6-27B-4.5b-mlx-AutoRound"

model, processor = load(model_name_or_path)
mlx_cfg = load_config(model_name_or_path)
prompt_text = "Describe this image in one sentence."
formatted = apply_chat_template(processor, mlx_cfg, prompt_text, num_images=1)
# Use a public example image so the test does not need local assets.
image_url = "https://qianwen-res.oss-accelerate.aliyuncs.com/Qwen3.5/demo/RealWorld/RealWorld-04.png"

output = generate(model, processor, formatted, image=[image_url], max_tokens=2048).text
print(output)

Ethical Considerations and Limitations

The model can produce factually incorrect output, and should not be relied on to produce factually accurate information. Because of the limitations of the pretrained model and the finetuning datasets, it is possible that this model could generate lewd, biased or otherwise offensive outputs.

Therefore, before deploying any applications of the model, developers should perform safety testing.

Caveats and Recommendations

Users (both direct and downstream) should be made aware of the risks, biases and limitations of the model.
