Fireworks AI

透過 Mastra 的模型路由器存取 17 個 Fireworks AI 模型。系統會自動使用 FIREWORKS_API_KEY 環境變數完成身分驗證。

如需進一步了解，請參閱Fireworks AI 文件。

.env

FIREWORKS_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: 'fireworks-ai/accounts/fireworks/models/deepseek-v4-flash',
})

// 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 endpoint。部分 Provider 特有功能可能無法使用，詳情請參閱Fireworks AI 文件。

const agent = new Agent({
  id: 'dynamic-agent',
  name: 'Dynamic Agent',
  model: ({ requestContext }) => {
    const useAdvanced = requestContext.task === 'complex'
    return useAdvanced
      ? 'fireworks-ai/accounts/fireworks/routers/kimi-k3-fast'
      : 'fireworks-ai/accounts/fireworks/models/deepseek-v4-flash'
  },
