Cloudflare Workers AI

通过 Mastra 的模型路由器访问 22 个 Cloudflare Workers AI 模型。系统会自动使用 CLOUDFLARE_API_KEY 环境变量完成身份验证。 Configure CLOUDFLARE_ACCOUNT_ID as well.

更多信息请参阅Cloudflare Workers AI 文档。

.env

CLOUDFLARE_ACCOUNT_ID=your-account-id

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: 'cloudflare-workers-ai/@cf/aisingapore/gemma-sea-lion-v4-27b-it',
})

// 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)
}

高级配置

自定义请求头

src/mastra/agents/my-agent.ts

const agent = new Agent({
  id: 'custom-agent',
  name: 'custom-agent',
  model: {
    url: 'https://api.cloudflare.com/client/v4/accounts/${CLOUDFLARE_ACCOUNT_ID}/ai/v1',
    id: 'cloudflare-workers-ai/@cf/aisingapore/gemma-sea-lion-v4-27b-it',
    apiKey: process.env.CLOUDFLARE_API_KEY,
    headers: {
      'X-Custom-Header': 'value',
    },
  },
})

动态选择模型

src/mastra/agents/my-agent.ts

const agent = new Agent({
  id: 'dynamic-agent',
  name: 'Dynamic Agent',
  model: ({ requestContext }) => {
    const useAdvanced = requestContext.task === 'complex'
    return useAdvanced
      ? 'cloudflare-workers-ai/@cf/zai-org/glm-5.2'
      : 'cloudflare-workers-ai/@cf/aisingapore/gemma-sea-lion-v4-27b-it'
  },
})
