Instructions to use zai-org/GLM-4.5-Air with libraries, inference providers, notebooks, and local apps. Follow these links to get started.

Libraries

How to use zai-org/GLM-4.5-Air with Transformers:

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

pipe = pipeline("text-generation", model="zai-org/GLM-4.5-Air")
messages = [
    {"role": "user", "content": "Who are you?"},
]
pipe(messages)

# Load model directly
from transformers import AutoTokenizer, AutoModelForCausalLM

tokenizer = AutoTokenizer.from_pretrained("zai-org/GLM-4.5-Air")
model = AutoModelForCausalLM.from_pretrained("zai-org/GLM-4.5-Air")
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]:]))

Add GPTQModel W4A16 INT format Quant ?

While quantization formats such as GGUF and AWQ are already available in the community, models in GPTQModel formats like W4A16 and W8A16 remain notably scarce. These formats demonstrate significant advantages in quantization effectiveness and reduced precision loss. Given that quantizing models using GPTQModel formats requires data calibration—a process challenging for general users to complete—it would be beneficial for organized community groups to share models in W4A16 and W8A16 formats. Such contributions would be highly anticipated.

Will be doing this shortly, watch quantizations, I'll post tomorrow after I've done some basic tests to ensure the quant doesn't break the model at W4A16 grp128. Will be RDNA 4 compatible.
