Libraries

How to use intel-ai/GLM-5.2-MXFP4-CT-AutoRound with Transformers:

# Use a pipeline as a high-level helper
from transformers import pipeline

pipe = pipeline("text-generation", model="intel-ai/GLM-5.2-MXFP4-CT-AutoRound")
messages = [
    {"role": "user", "content": "Who are you?"},
]
pipe(messages)

# pip install -U transformers accelerate
# Load model directly
from transformers import AutoTokenizer, AutoModelForCausalLM

tokenizer = AutoTokenizer.from_pretrained("intel-ai/GLM-5.2-MXFP4-CT-AutoRound")
model = AutoModelForCausalLM.from_pretrained("intel-ai/GLM-5.2-MXFP4-CT-AutoRound", device_map="auto")
messages = [
    {"role": "user", "content": "Who are you?"},
]
inputs = tokenizer.apply_chat_template(
	messages,
	add_generation_prompt=True,
	tokenize=True,
	return_dict=True,
	return_tensors="pt",
).to(model.device)

outputs = model.generate(**inputs, max_new_tokens=256)
print(tokenizer.decode(outputs[0][inputs["input_ids"].shape[-1]:]))

Model Details

This model is an MXFP4 (mixed MXFP4 experts / BF16 linear) model of zai-org/GLM-5.2 generated by intel/auto-round using RTN. Please follow the license of the original model.

Quantized (MXFP4): routed experts
Kept in BF16: router / embeddings / lm_head

How to Use

Environment

    --output_dir GLM-5.2-MXFP4-CT-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. Here are a couple of useful links to learn more about Intel's AI software:
