Best Practices for GLM-5.1 Integration

1. Prompt Engineering

system_prompt = """
You are an expert software engineer specializing in Python development.
Follow these guidelines:
1. Write clean, PEP-8 compliant code
2. Include type hints for all functions
3. Add docstrings for documentation
4. Handle edge cases appropriately
"""

2. Temperature and Sampling Settings

• Creative tasks (writing, brainstorming): <code>temperature=0.8-1.0</code>

• Balanced responses: <code>temperature=0.5-0.7</code>

• Factual/technical tasks: <code>temperature=0.1-0.3</code>

3. Context Management

• Token costs and latency

• Information relevance and positioning

• Using retrieval-augmented generation (RAG) for large knowledge bases

4. Error Handling

from zhipuai import ZhipuAI
import time

client = ZhipuAI(api_key="your_api_key_here")

def robust_api_call(prompt, max_retries=3):
    """
    Make a robust API call with retry logic
    """
    for attempt in range(max_retries):
        try:
            response = client.chat.completions.create(
                model="glm-5.1-70b",
                messages=[{"role": "user", "content": prompt}],
                timeout=30,
            )
            return response.choices[0].message.content
            
        except Exception as e:
            if attempt < max_retries - 1:
                wait_time = 2 ** attempt  # Exponential backoff
                print(f"Error: {e}. Retrying in {wait_time}s...")
                time.sleep(wait_time)
            else:
                raise Exception(f"API call failed after {max_retries} attempts: {e}")
    
    return None
