Instructions to use zai-org/GLM-5.3 with libraries, inference providers, notebooks, and local apps. Follow these links to get started.

Libraries

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)

# pip install -U transformers accelerate
# 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=256)
print(tokenizer.decode(outputs[0][inputs["input_ids"].shape[-1]:]))

	-H "Content-Type: application/json" \
	--data '{
		"model": "zai-org/GLM-5.3",
		"messages": [
			{
				"role": "user",
				"content": "What is the capital of France?"
			}
		]
	}'

Use Docker

docker model run hf.co/zai-org/GLM-5.3

Add LHTB 2.0 (Long-Horizon Terminal-Bench) eval result: 12/77 tasks solved

Browse files

Adds the **Long-Horizon Terminal-Bench 2.0 (LHTB 2.0)** result for GLM-5.3 so it appears on the [LHTB benchmark leaderboard](https://huggingface.co/datasets/IntelligenceLab/Long-Horizon-Terminal-Bench) under the `lhtb2_solved` task.

**Score: 12 / 77** tasks solved at reward >= 0.95 (pass@0.95)

| Metric | Value |
|---|---|
| Solved (reward >= 0.95) | 12 / 77 |
| Strict pass (reward = 1.0) | 9 / 77 |
| Mean reward (77 tasks) | 0.542 |
| Agent | terminus-2 (official LHTB Harbor harness) |
| Budget | 3 hours per task, 1 trial per task |

LHTB measures how well agents sustain useful work in a containerized terminal
over hundreds of steps, graded by hidden rebuild-from-artifact verifiers. LHTB 2.0
has 77 tasks: the original 46 plus 31 new ones, 30 of them reconstruction tasks.

Full results, with per-task rewards and trajectories linked from there:
https://github.com/zli12321/LHTB/tree/lhtb-2.0#lhtb-20-results-october-2026

Submitted by the LHTB maintainers; happy to adjust the formatting or withdraw if you prefer.
