Usage

Config Environment Variables

You can use either Fullstack or Client-Server mode.

Fullstack

Set following environment variables in .env file or Vercel.

Key	Value	Required
CF_USER_ID	Cloudflare user id	✅
CF_AI_API_KEY	Cloudflare AI api key	✅
HF_API_KEY	HuggingFace api key

The free plan of Vercel has a limit of 10s for each request, which may cause 504 error (especially when using HuggingFace models). You can subscribe to a Vercel paid plan, run the server locally, or use Client-Server mode.

Client-Server

Deploy the server to Cloudflare Workers (see this project) and set following environment variables in .env file or Vercel.

Key	Value	Required
NEXT_PUBLIC_WORKERS_SERVER	Server url (e.g. https://api.xxx.workers.dev)	✅

Once NEXT_PUBLIC_WORKERS_SERVER is set, all the other environment variables will be ignored.

Deploy

Deploy this project to Vercel (remember to set environment variables).

Common Issues

• 429 error: You may have exceeded the HuggingFace api request limit. Please wait for a while, reduce the frequency of requests, and consider subscribing to a paid plan.
• 504 error: The request have exceeded the Vercel time limit. See above for resolution.
