Instructions to use RedHatAI/GLM-5.2-NVFP4 with libraries, inference providers, notebooks, and local apps. Follow these links to get started.

Libraries

How to use RedHatAI/GLM-5.2-NVFP4 with Transformers:

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

pipe = pipeline("text-generation", model="RedHatAI/GLM-5.2-NVFP4")
messages = [
    {"role": "user", "content": "Who are you?"},
]
pipe(messages)

# Load model directly
from transformers import AutoTokenizer, AutoModelForCausalLM

tokenizer = AutoTokenizer.from_pretrained("RedHatAI/GLM-5.2-NVFP4")
model = AutoModelForCausalLM.from_pretrained("RedHatAI/GLM-5.2-NVFP4")
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=40)
print(tokenizer.decode(outputs[0][inputs["input_ids"].shape[-1]:]))

	-H "Content-Type: application/json" \
	--data '{
		"model": "RedHatAI/GLM-5.2-NVFP4",
		"messages": [
			{
				"role": "user",
				"content": "What is the capital of France?"
			}
		]
	}'

Use Docker

docker model run hf.co/RedHatAI/GLM-5.2-NVFP4

Safetensors File Size < 50 GB?

Thank you for this model. Can you maybe in future create files < 50 GB? At work, we can only access Huggingface through a proxy. Therefore, XET doesn't work through the proxy. Huggingface doesn't allow downloading files >= 50 GB without XET (I have hf_xet installed):

Error: Invalid value. The file is too large to be downloaded using the regular download method.  Install `hf_xet` with `pip install hf_xet` for xet-powered downloads.

Edit: I found if I use curl instead of hf, it works:

curl -L -O -H "Authorization: Bearer $HF_TOKEN" "$HF_ENDPOINT/RedHatAI/GLM-5.2-NVFP4/resolve/main/model-00003-of-00009.safetensors"
