Model Details

This model is an int4 model with group_size 128 and quantized lm-head of THUDM/glm-4-9b-chat generated by intel/auto-round. For GPTQ format, please load the model with revision d1bb095

How To Use

INT4 Inference on CPU/CUDA/HPU

python

from auto_round import AutoRoundConfig ## must import for auto-round format
from transformers import AutoModelForCausalLM, AutoTokenizer
import torch

quantized_model_dir = "OPEA/glm-4-9b-chat-int4-inc"

model = AutoModelForCausalLM.from_pretrained(quantized_model_dir,
                                             device_map=backend.split(':')[0],                                                                                                torch_dtype=torch.float16,
                                             quantization_config=quantization_config,
                                             trust_remote_code=True 
                                            ).eval()

tokenizer = AutoTokenizer.from_pretrained(quantized_model_dir, trust_remote_code=True)
query = "请介绍一下智谱华章科技有限公司"
inputs = tokenizer.apply_chat_template([{"role": "user", "content": query}],
                                       add_generation_prompt=True,
                                       tokenize=True,
                                       return_tensors="pt",
                                       return_dict=True
                                       )
inputs = inputs.to(model.device)

gen_kwargs = {"max_length": 50, "do_sample": False, "top_k": 1}##change this to follow official usage
with torch.no_grad():
    outputs = model.generate(**inputs, **gen_kwargs)
    outputs = outputs[:, inputs['input_ids'].shape[1]:]
    print(tokenizer.decode(outputs[0], skip_special_tokens=True))

Generate the model

Here is the sample command to generate the model.

bash

auto-round \
--model THUDM/glm-4-9b-chat \
--iter 1000 \
--nsamples 512 \
--disable_eval \
--quant_lm_head \
--format "auto_round"
--output_dir "./tmp_autoround" 

copy all the *.py file to the quantized_model folder

For gptq format, need to add "block_name_to_quantize":"transformer.encoder.layers" to config.json, we only tested it on transformers==4.46.1

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.
