Access 4 Zhipu AI Coding Plan models through Mastra's model router. Authentication is handled automatically using the `ZHIPU_API_KEY` environment variable.

Learn more in the [Zhipu AI Coding Plan documentation](https://docs.bigmodel.cn/cn/coding-plan/overview).

.env

```bash
ZHIPU_API_KEY=your-api-key
```

src/mastra/agents/my-agent.ts

```typescript
import { Agent } from "@mastra/core/agent";

const agent = new Agent({
  id: "my-agent",
  name: "My Agent",
  instructions: "You are a helpful assistant",
  model: "zhipuai-coding-plan/glm-4.5-air"
});

// 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 [Zhipu AI Coding Plan documentation](https://docs.bigmodel.cn/cn/coding-plan/overview) for details.
