AgentRouter

透過 Mastra 的模型路由器存取 20 個 AgentRouter 模型。系統會自動使用 AGENTROUTER_API_KEY 環境變數進行驗證。

詳情請參閱AgentRouter 文件。

AGENTROUTER_API_KEY=your-api-key

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

const agent = new Agent({
  id: 'my-agent',
  name: 'My Agent',
  instructions: 'You are a helpful assistant',
  model: 'agentrouter/claude-3-5-haiku-20241022',
})

// 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AgentRouter 文件。

進階設定

自訂標頭

const agent = new Agent({
  id: 'custom-agent',
  name: 'custom-agent',
  model: {
    url: 'https://agentrouter.org/v1',
    id: 'agentrouter/claude-3-5-haiku-20241022',
    apiKey: process.env.AGENTROUTER_API_KEY,
    headers: {
      'X-Custom-Header': 'value',
    },
  },
})

動態選擇模型

const agent = new Agent({
  id: 'dynamic-agent',
  name: 'Dynamic Agent',
  model: ({ requestContext }) => {
    const useAdvanced = requestContext.task === 'complex'
    return useAdvanced ? 'agentrouter/kimi-k2-thinking' : 'agentrouter/claude-3-5-haiku-20241022'
  },
})
