Getting Started with GLM-5.2 API

import os
from zhipuai import ZhipuAI

# Initialize the client with your API key
client = ZhipuAI(api_key=os.environ.get("ZHIPU_API_KEY"))

def generate_response(prompt, model="glm-5.2"):
    """
    Generate a response using GLM-5.2 model.
    
    Args:
        prompt (str): The input prompt for the model
        model (str): The model version to use
    
    Returns:
        str: The generated response
    """
    response = client.chat.completions.create(
        model=model,
        messages=[
            {"role": "user", "content": prompt}
        ],
        temperature=0.7,
        max_tokens=2048,
    )
    
    return response.choices[0].message.content

# Example usage
if __name__ == "__main__":
    question = "Explain the concept of transformer attention mechanisms in both English and Chinese."
    answer = generate_response(question)
    print(answer)

Function Calling and Tool Integration

import json
from zhipuai import ZhipuAI

client = ZhipuAI(api_key=os.environ.get("ZHIPU_API_KEY"))

# Define available tools
tools = [
    {
        "type": "function",

Practical Applications and Use Cases

Enterprise Document Processing

def summarize_document(document_text):
    """
    Summarize a long document using GLM-5.2's extended context.
    
    Args:
        document_text (str): Full document text (up to 128K tokens)
    
    Returns:
        str: Executive summary of the document
    """
    prompt = f"""Please provide a comprehensive executive summary of the following document. 
    Include key points, actionable insights, and important statistics.
    
    Document:
    {document_text}
    
    Summary:"""
    
    response = client.chat.completions.create(
        model="glm-5.2",
        messages=[{"role": "user", "content": prompt}],
        max_tokens=1024,
        temperature=0.3  # Lower temperature for factual summarization
    )
    
    return response.choices[0].message.content

Code Analysis and Generation

def analyze_code(code_snippet, language="python"):
    """
    Analyze code and provide improvement suggestions.
    
    Args:
        code_snippet (str): The code to analyze
        language (str): Programming language
    
    Returns:
        str: Analysis and recommendations
    """
    prompt = f"""Analyze the following {language} code for:
    1. Potential bugs or errors
    2. Performance optimizations
    3. Best practice violations
    4. Security concerns

    Code:

"""
    
    response = client.chat.completions.create(
        model="glm-5.2",
        messages=[{"role": "user", "content": prompt}],
        max_tokens=2048
    )
    
    return response.choices[0].message.content

Best Practices for Implementation

1. Optimize Token Usage

def estimate_tokens(text):
    """
    Rough estimate of token count for text.
    Generally: 1 token ≈ 4 characters for English, ≈ 1.5 characters for Chinese.
    """
    # This is a simplified estimation
    english_chars = sum(1 for c in text if ord(c) < 128)
    chinese_chars = len(text) - english_chars
    
    estimated_tokens = (english_chars / 4) + (chinese_chars / 1.5)
    return int(estimated_tokens)

2. Implement Proper Error Handling

import time
from zhipuai import APIError, RateLimitError

def robust_api_call(prompt, max_retries=3, delay=1):
    """
    Make API call with retry logic and error handling.
    """
    for attempt in range(max_retries):
        try:
            response = client.chat.completions.create(
                model="glm-5.2",
                messages=[{"role": "user", "content": prompt}]
            )
            return response.choices[0].message.content
        
        except RateLimitError:
            if attempt < max_retries - 1:
                time.sleep(delay * (attempt + 1))
                continue
            raise Exception("Rate limit exceeded, please try again later")
        
        except APIError as e:
            raise Exception(f"API error occurred: {str(e)}")
    
    raise Exception("Max retries exceeded")

3. Leverage System Prompts for Consistency

def create_specialized_assistant(domain, language="bilingual"):
    """
    Create a specialized assistant with domain expertise.
    """
    system_prompts = {
        "legal": "You are a legal expert assistant. Provide accurate legal information with appropriate disclaimers. Always cite relevant laws and regulations.",
        "technical": "You are a senior software engineer. Provide detailed technical explanations with code examples. Focus on best practices and performance.",
        "business": "You are a business analyst. Provide strategic insights backed by data. Structure your responses with clear recommendations."
    }
    
    return system_prompts.get(domain, "You are a helpful assistant.")

Performance Benchmarks and Comparisons

• MMLU: Strong performance on the Massive Multitask Language Understanding benchmark

• C-Eval: Leading scores on Chinese evaluation benchmarks

• GSM8K: Improved mathematical reasoning capabilities

• HumanEval: Competitive code generation abilities

Considerations and Limitations

1. API Availability: Access may be restricted in certain regions; verify availability for your deployment location.

1. Compliance Requirements: Organizations handling sensitive data should review data handling policies.

1. Model Updates: Stay informed about model updates and version changes that may affect behavior.

1. Cost Management: Extended context usage can increase costs; implement appropriate monitoring.
