submodel

透過 Mastra 的模型路由器存取 9 個 submodel 模型。系統會自動使用 SUBMODEL_INSTAGEN_ACCESS_KEY 環境變數完成身分驗證。

如需進一步了解，請參閱submodel 文件。

.env

SUBMODEL_INSTAGEN_ACCESS_KEY=your-api-key

src/mastra/agents/my-agent.ts

import { Agent } from '@mastra/core/agent'

const agent = new Agent({
  id: 'my-agent',
  name: 'My Agent',
  instructions: 'You are a helpful assistant',
  model: 'submodel/Qwen/Qwen3-235B-A22B-Instruct-2507',
})

// 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)
}

資訊

Mastra 使用與 OpenAI 相容的 /chat/completions endpoint。部分 Provider 特有功能可能無法使用，詳情請參閱submodel 文件。
