Helicone 標誌Helicone

透過 Mastra 的模型路由器存取 90 個 Helicone 模型。系統會自動使用 HELICONE_API_KEY 環境變數進行驗證。

詳情請參閱Helicone 文件。

.env
HELICONE_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: 'helicone/chatgpt-4o-latest',
})

// 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Helicone 文件。
