Cloudflare Workers AI

Workers AI 在 Cloudflare 边缘运行推理，Worker 调模型不必绕道区域 GPU 集群。免费单位是每天 10,000 个 neuron，整个目录共享。Llama 3.3 70B、GPT-OSS 120B 和 Qwen 3.8 都在这个档内。

代码示例

npm install openai

import OpenAI from 'openai'

const client = new OpenAI({
  baseURL: 'https://api.cloudflare.com/client/v4/accounts/{account_id}/ai/v1',
  apiKey: process.env.CLOUDFLARE_API_TOKEN
})

const response = await client.chat.completions.create({
  model: '@cf/openai/gpt-oss-120b',
  messages: [{ role: 'user', content: 'Explain closures in one paragraph.' }]
})

console.log(response.choices[0].message.content)

pip install openai

import os
from openai import OpenAI

client = OpenAI(
    base_url="https://api.cloudflare.com/client/v4/accounts/{account_id}/ai/v1",
    api_key=os.environ["CLOUDFLARE_API_TOKEN"],
)

response = client.chat.completions.create(
    model="@cf/openai/gpt-oss-120b",
    messages=[{"role": "user", "content": "Explain closures in one paragraph."}],
)

print(response.choices[0].message.content)

curl https://api.cloudflare.com/client/v4/accounts/{account_id}/ai/v1/chat/completions \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer $CLOUDFLARE_API_TOKEN" \
  -d '{
    "model": "@cf/openai/gpt-oss-120b",
    "messages": [{"role": "user", "content": "Explain closures in one paragraph."}]
  }'

值得注意

把接口地址里的 {account_id} 换成你自己的账户 id。
在 Worker 内部请改用 AI 绑定 —— 免去网络跳转和 token。
Kimi K2.6、GLM 5.2/5.3 和 DeepSeek V4 仅限 Workers Paid。最长免费窗口是 Qwen 3.8 27B 的 262K。
