OPEA/Llama-3.2V-11B-cot-int4-sym-inc

Model Details

This model is an int4 model(The vision module has also been quantized) with group_size 128 and symmetric quantization of Xkev/Llama-3.2V-11B-cot generated by intel/auto-round.

How To Use

Requirements

Please use Transformers version 4.45.0 or later AutoRound version >= 0.4.1

Generate the model

Here is the sample command to reproduce the model.

pip install auto-round
auto-round-mllm \
--model Xkev/Llama-3.2V-11B-cot \
--device 0 \
--group_size 128 \
--bits 4 \
--iters 200 \
--nsample 128 \
--seqlen 512 \
--quant_nontext_module \
--format 'auto_round' \
--output_dir "./tmp_autoround"

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.
