gemma-4-31B-it-int4-AutoRound

Model Details

This model is an int4 model with group_size 128 and symmetric quantization of google/gemma-4-31B-it generated by intel/auto-round. Please follow the license of the original model.

A youtube video by Fahd Mirza demonstrates how to use this model.

> These weights are byte-identical to [`Intel/gemma-4-31B-it-int4-AutoRound`](https://huggingface.co/Intel/gemma-4-31B-it-int4-AutoRound), re-hosted here
> for use on Meganova infrastructure. The int4 AutoRound quantization is the work of **Intel**, not
> ours — we have not modified the weights. Byte-identity was verified against
> the upstream shard sizes.

The view is taken from the shore near Fort Point, showing the bridge's iconic International Orange color, one of its large towers, and the suspension cables stretching across the water. In the foreground, there is a rocky coastline with a small rock in the water, and the historic Fort Point building is visible on the left.", 'role': 'assistant'}

Generate the Model

https://github.com/intel/auto-round/pull/1656 is required

auto-round
/models/gemma-4-31B-it
--output_dir
"./quantized"
--scheme
W4A16

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.
