Model Details
This model is an MXFP8 (W8A8, group_size 32) model of Qwen/Qwen3.8-27B generated by intel/auto-round using RTN. Please follow the license of the original model.
- Quantized (MXFP8): MLP, attention, linear attention
- Kept in BF16: embeddings, lm_head, vision tower, MTP
How to Use

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.
