使用 Workers AI REST API

本指南将指导您设置并部署您的第一个 Workers AI 项目。您将使用 Workers AI REST API 来试验一个大型语言模型（LLM）。

前提条件

如果您还没有，那么请注册一个 Cloudflare 账户。

1. 获取 API 令牌和账户 ID

您需要您的 API 令牌和账户 ID 来使用 REST API。

获取这些值的步骤：

登录到 Cloudflare 控制面板并选择您的账户。
转到 AI > Workers AI。
选择使用 Workers AI API。
获取您的 API 令牌：
- 选择获取 API 令牌。
- 审查预填信息。
- 选择继续到摘要。
- 选择创建令牌。
- 复制令牌值以备后用。
获取您的账户 ID：
- 回到使用 Workers AI API 的屏幕（您最初的标签页）。
- 在获取账户 ID 下，复制账户 ID 的值。

如果您选择创建一个 API 令牌而不使用模板，该令牌将需要 Workers AI - 读取和 Workers AI - 编辑的权限。

2. 通过 API 运行模型

创建您的 API 令牌后，使用您的 API 令牌在请求中进行身份验证并向 API 发出请求。

您将使用执行 AI 模型端点来运行 @cloudflare/meta-llama/llama-2-7b-chat-int8 模型：

$ curl https://api.cloudflare.com/client/v4/accounts/{ACCOUNT_ID}/ai/run/@cf/meta/llama-2-7b-chat-int8 \
  -H 'Authorization: Bearer {API_TOKEN}' \
  -d '{ "prompt": "Where did the phrase Hello World come from" }'
