Model Details

This model is an int4 model with group_size 128 of tiiuae/falcon-7b generated by intel/auto-round.

How To Use

INT4 Inference with AutoGPTQ

##pip install auto-gptq[triton] 
##pip install triton==2.2.0
from auto_gptq import AutoGPTQForCausalLM
from transformers import AutoTokenizer
quantized_model_dir = "Intel/falcon-7b-int4-inc"
tokenizer = AutoTokenizer.from_pretrained(quantized_model_dir)


model = AutoGPTQForCausalLM.from_quantized(quantized_model_dir, device="cuda:0", use_safetensors=True, use_triton=True,
                                           trust_remote_code=True)

pipeline = transformers.pipeline(
    "text-generation",
    model=model,
    tokenizer=tokenizer,
    trust_remote_code=True,
    device_map="auto",
)
sequences = pipeline(
   "There is a girl who likes adventure,",
    max_length=200,
    do_sample=True,
    top_k=10,
    num_return_sequences=1,
    eos_token_id=tokenizer.eos_token_id,
)
for seq in sequences:
    print(f"Result: {seq['generated_text']}")

Evaluate the model

Install lm-eval-harness from source, and the git id 96d185fa6232a5ab685ba7c43e45d1dbb3bb906d,

pip install auto-gptq[triton]

pip install triton==2.2.0

Since we encountered an issue evaluating this model with lm-eval, we opted to evaluate the qdq model instead. In our assessment, we found that its accuracy closely matches that of the real quantized model in most cases except for some small models like opt-125m. The batch size 32 is used.

Reproduce the model

Here is the sample command to reproduce the model

git clone https://github.com/intel/auto-round
cd auto-round/examples/language-modeling
pip install -r requirements.txt
python3 main.py \
--model_name  tiiuae/falcon-7b \
--device 0 \
--group_size 128 \
--bits 4 \
--iters 1000 \
--disable_quanted_input \
--deployment_device 'gpu' \
--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.
