Model Details

This model is an W4A16 model with group_size 128 of stepfun-ai/NextStep-1.1 generated by intel/auto-round. Please follow the license of the original model.

Infernece Example

bash

hf download INCModel/NextStep-1.1-W4A16-AutoRound  /workspace/models/stepfun-ai/NextStep-1.1-W4A16/
export PYTHONPATH=/workspace/models/stepfun-ai/NextStep-1.1-W4A16/
cd /workspace/models/stepfun-ai/NextStep-1.1-W4A16/
uv pip install transformers==4.57.6
uv pip install gptqmodel==5.8.0 --no-build-isolation
python run_generation.py

python

# run_generation.py

# load model and tokenizer
tokenizer = AutoTokenizer.from_pretrained(HF_HUB, local_files_only=True, trust_remote_code=True)

# set device_map="cuda" to leverage gptqmodel kernels
model = AutoModel.from_pretrained(HF_HUB, local_files_only=True, trust_remote_code=True, device_map="cuda")

Tuning version

bash

hf download stepfun-ai/NextStep-1.1  /workspace/models/stepfun-ai/NextStep-1.1
export PYTHONPATH=/workspace/models/stepfun-ai/NextStep-1.1/
cd /workspace/models/stepfun-ai/NextStep-1.1/

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.
