INT4 Inference on CPU/Intel GPU/CUDA

from transformers import AutoModelForCausalLM, AutoTokenizer

model_name = "Intel/Qwen3-235B-A22B-Instruct-2507-int4-AutoRound"

# load the tokenizer and the model
tokenizer = AutoTokenizer.from_pretrained(model_name)
model = AutoModelForCausalLM.from_pretrained(
    model_name,
    torch_dtype="auto",
    device_map="auto"
)

# prepare the model input
prompt = "Give me a short introduction to large language model."
messages = [
    {"role": "user", "content": prompt}

    messages,
    tokenize=False,
    add_generation_prompt=True,
)
model_inputs = tokenizer([text], return_tensors="pt").to(model.device)

# conduct text completion

"""
content: A large language model (LLM) is a type of artificial intelligence trained on vast amounts of text data to understand and generate human-like language.
 Using deep learning techniques, particularly transformer architectures, LLMs learn patterns, grammar, facts, and reasoning abilities from diverse sources like books, websites, and articles.
 They can perform a wide range of language tasks, such as answering questions, writing stories, coding, and translating languages. Examples include models like GPT, Llama, and PaLM.
 Their power comes from their size—often billions of parameters—and extensive training, enabling them to produce coherent and contextually relevant responses.

Generate the model

Here is the sample command to reproduce the model

auto-round --model Qwen/Qwen3-235B-A22B-Instruct-2507 --output_dir ./Qwen3-235B-A22B-Instruct-2507-int4 --enable_torch_compile  --nsamples 512 --fp_layers mlp.gate

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.
