Features

• Generate high-quality images using Cloudflare's Flux-1-Schnell model
• Request proxying through Cloudflare Worker for simplified authentication
• Generate and view images directly in LobeChat conversations

Setup Steps

1. Set up Cloudflare Worker

   • Deploy the provided Worker code to Cloudflare Workers
   • Configure the following environment variables (Secrets) in your Worker settings:
     • WORKER_API_KEY: Set a secure API key for client authentication
     • CLOUDFLARE_API_TOKEN: Your Cloudflare API token
     • CLOUDFLARE_ACCOUNT_ID: Your Cloudflare account ID

2. Configure the plugin in LobeChat

   • Add this plugin to LobeChat
   • In the configuration page:
     • Configure your Worker API key as WORKER_API_KEY
     • Ensure the Worker URL is correctly configured

Authentication and Parameters

This plugin uses the following configuration to access your Cloudflare Worker:

• Worker API key: Used as the X-Api-Key request header
• You only need to provide the image description (prompt) when using this plugin
• The Worker automatically calls the Cloudflare AI API using the configured credentials

Usage Instructions

1. In the chat, request to generate an image, for example:

   • "Draw a cat standing on a mountain top"
   • "Generate a beach sunset landscape"

2. Supported parameters:

   • prompt: Image description (required, maximum 2048 characters)
   • steps: Number of diffusion steps (optional, default 4, maximum 8)

   Example: "Generate an image of an astronaut riding a horse, using 8 diffusion steps"

  -d '{ "prompt": "cyberpunk cat", "steps": 8 }'

Limitations

• There may be usage limitations based on your Cloudflare account type
• The Flux-1-Schnell model has its own capability range; not all prompts will produce ideal results
