Perplexity Agent

通过 Mastra 的模型路由器访问 20 个 Perplexity Agent 模型。系统会自动使用 PERPLEXITY_API_KEY 环境变量完成身份验证。

更多信息请参阅Perplexity Agent 文档。

.env

PERPLEXITY_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: 'perplexity-agent/anthropic/claude-haiku-4-5',
})

// 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)
}

信息

Mastra 使用兼容 OpenAI 的 /chat/completions endpoint。部分 Provider 特有功能可能不可用，详情请参阅Perplexity Agent 文档。

    return useAdvanced
      ? 'perplexity-agent/xai/grok-4-1-fast-non-reasoning'
      : 'perplexity-agent/anthropic/claude-haiku-4-5'
  },
})
