Using the openai Python package, which supports Z.ai’s API endpoint, you can interact with GLM-5.1 easily.

from openai import OpenAI

# Initialize the client with Z.ai's API base URL
client = OpenAI(
    api_key="your-zai-api-key",
    base_url="https://open.bigmodel.cn/api/paas/v4/"
)

# Use GLM-5.1 for a complex reasoning task
response = client.chat.completions.create(
    model="glm-5-1",
    messages=[
        {"role": "system", "content": "You are a helpful assistant specializing in financial analysis."},
        {"role": "user", "content": "Analyze the potential impact of DeepSeek's price war on Zhipu AI's market position."}
    ],
    temperature=0.7,
    max_tokens=1024
)

print(response.choices[0].message.content)

2. Agentic Tool Calling (Python with LangChain)

GLM-5.1 is optimized for agentic workflows. Here’s how to use it with LangChain to call external tools.

from langchain_openai import ChatOpenAI
from langchain.tools import tool
from langchain.agents import initialize_agent, AgentType

# Define a simple tool
@tool
def get_current_weather(location: str):
    """Get the current weather in a given location."""
    return f"The weather in {location} is sunny and 25°C."

# Initialize GLM-5.1 via LangChain's OpenAI-compatible interface
llm = ChatOpenAI(
    model="glm-5-1",
    openai_api_key="your-zai-api-key",
    openai_api_base="https://open.bigmodel.cn/api/paas/v4/"
)

tools = [get_current_weather]

# Initialize the agent
agent = initialize_agent(
    tools,
    llm,
    agent=AgentType.CHAT_ZERO_SHOT_REACT_DESCRIPTION,
    verbose=True
)

# Run the agent
agent.run("What is the weather in Beijing?")

3. TypeScript Integration with Vercel AI SDK

For modern web apps, use the zhipu-ai-provider with Vercel’s AI SDK.

import { createOpenAI } from '@ai-sdk/openai';
import { streamText } from 'ai';

// Configure the Z.ai provider
const zai = createOpenAI({
  name: 'zai',
  apiKey: process.env.ZAI_API_KEY,
  baseURL: 'https://open.bigmodel.cn/api/paas/v4/',
});

export async function generateResponse(userMessage: string) {
  const result = streamText({
    model: zai('glm-5-1'),
    messages: [
      { role: 'system', content: 'You are a coding assistant.' },
      { role: 'user', content: userMessage },
    ],
    maxTokens: 512,
  });

  return result.toTextStreamResponse();
}
