INCModel4/Phi-4-multimodal-instruct-W4A16-AutoRound

Model Details

This model is an int4 (W4A16, group_size 128, symmetric) model of microsoft/Phi-4-multimodal-instruct generated by intel/auto-round with 200 tuning iterations. Please follow the license of the original model.

• Quantized (W4A16): text decoder linear projections
• Kept in BF16: LoRA adapters, token embeddings, lm_head, vision and audio components, normalization layers

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. Here are a couple of useful links to learn more about Intel's AI software:
