How to use zai-org/GLM-5.3 with Transformers:
# Use a pipeline as a high-level helper from transformers import pipeline pipe = pipeline("text-generation", model="zai-org/GLM-5.3") messages = [ {"role": "user", "content": "Who are you?"}, ] pipe(messages)# Load model directly from transformers import AutoTokenizer, AutoModelForCausalLM tokenizer = AutoTokenizer.from_pretrained("zai-org/GLM-5.3") model = AutoModelForCausalLM.from_pretrained("zai-org/GLM-5.3", 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=40) print(tokenizer.decode(outputs[0][inputs["input_ids"].shape[-1]:])) - Inference

How to use zai-org/GLM-5.3 with Docker Model Runner:
docker model run hf.co/zai-org/GLM-5.3
More refusals than 5.2
The model is fantastic but the refusals irk me. In fact the refusals are exactly like Claude's - using exactly the same language and reasoning. I understand everybody trains on each other's data now but at least filter out the refusals that Claude put in place while training the model.
I am thankful to Z.ai for this otherwise wonderful release.
Thats horrible. I asked glm 5.2 once the strength of a robot arms and in squatting. Glm 5.2 went off the deep end and said its forbidden because strength in hydraulic robotic limbs are for killing machines. Lol. If glm 5.3 is more restrictive its almost not useable.
