STACKIT

透過 Mastra 的模型路由器存取 8 個 STACKIT 模型。系統會自動使用 STACKIT_API_KEY 環境變數進行驗證。

詳情請參閱STACKIT 文件。

.env

STACKIT_API_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: 'stackit/Qwen/Qwen3-VL-235B-A22B-Instruct-FP8',
})

// 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 端點。部分 Provider 專屬功能可能無法使用，詳情請參閱STACKIT 文件。

動態選擇模型

src/mastra/agents/my-agent.ts

const agent = new Agent({
  id: 'dynamic-agent',
  name: 'Dynamic Agent',
  model: ({ requestContext }) => {
    const useAdvanced = requestContext.task === 'complex'
    return useAdvanced
      ? 'stackit/openai/gpt-oss-20b'
      : 'stackit/Qwen/Qwen3-VL-235B-A22B-Instruct-FP8'
  },
})
