Xpersona

通过 Mastra 的模型路由器访问 13 个 Xpersona 模型。系统会自动使用 XPERSONA_API_KEY 环境变量完成身份验证。

更多信息请参阅Xpersona 文档。

.env

XPERSONA_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: 'xpersona/claude-fable-5',
})

// 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)
}
