Getting Started with GLM-5
Installation Options
Option 1: Using Hugging Face
The easiest way to start with GLM-5 is through Hugging Face:
pip install transformers accelerate
from transformers import AutoTokenizer, AutoModelForCausalLM
tokenizer = AutoTokenizer.from_pretrained("zhipuai/glm-5-9b-chat", trust_remote_code=True)
model = AutoModelForCausalLM.from_pretrained("zhipuai/glm-5-9b-chat", trust_remote_code=True)
Option 2: llama.cpp
For efficient local inference:
git clone https://github.com/ggerganov/llama.cpp
cd llama.cpp
make
Download the quantized model and run:
./main -m models/glm-5-9b-chat-q4_k_m.gguf -p "Your prompt here"
Option 3: Ollama
The simplest approach for macOS and Linux:
# Install Ollama from https://ollama.com
ollama run glm-5
Basic Usage Example
from transformers import AutoTokenizer, AutoModelForCausalLM
import torch
# Load model and tokenizer
tokenizer = AutoTokenizer.from_pretrained(
"zhipuai/glm-5-9b-chat",
trust_remote_code=True
)
model = AutoModelForCausalLM.from_pretrained(
"zhipuai/glm-5-9b-chat",
trust_remote_code=True,
torch_dtype=torch.float16
).cuda()
# Generate response
messages = [
{"role": "user", "content": "Explain the benefits of open-source AI models."}
]
inputs = tokenizer.apply_chat_template(messages, return_tensors="pt")
outputs = model.generate(inputs, max_new_tokens=512, temperature=0.7)
response = tokenizer.decode(outputs[0], skip_special_tokens=True)
print(response)
Best Practices
- Quantization: Use INT4 or INT8 for production to reduce memory usage
- Prompt Engineering: Clear, specific prompts yield better results
- Temperature Settings: Lower (0.1-0.5) for factual tasks, higher (0.7-1.0) for creative tasks
- Context Management: Keep context length appropriate for your task
