Intel / gpt-oss-20b-int4-rtn-AutoRound

Model Details

This model is a mixed int4 model with group_size 128 and symmetric quantization of openai/gpt-oss-20b generated by intel/auto-round via RTN (no algorithm tuning). Following the official model, Non expert layers fallback to 16bits.

Theoretically, this one( https://huggingface.co/Intel/gpt-oss-20b-int4-AutoRound ) is better

How To Use

this model could not run on vLLM

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.
