Z.AI Coding Plan
Access 5 Z.AI Coding Plan models through Mastra’s model router. Authentication is handled automatically using the ZHIPU_API_KEY
environment variable.

import { Agent } from "@mastra/core";
const agent = new Agent({
name: "my-agent",
instructions: "You are a helpful assistant",
model: "zai-coding-plan/glm-4.5"
});
// Generate a response
const response = await agent.generate("Hello!");
// Stream a response
const stream = await agent.stream("Tell me a story");
for await (const chunk of stream) {
console.log(chunk);
}
Mastra uses the OpenAI-compatible /chat/completions
endpoint. Some provider-specific features may not be available. Check the Z.AI Coding Plan documentation for details.
