SGLang Diffusion WebUI User Guide

SGLang Diffusion WebUI provides an intuitive Gradio-based interface for image and video generation, supporting parameter tuning and real-time previews.

Prerequisites

The WebUI runs on Gradio. To get started, install Gradio first:

pip install gradio==6.1.0

Launch WebUI Service

SGLang Diffusion now includes an integrated WebUI. Simply add the --webui parameter when starting the service.

Launch Text-to-Image Service

sglang serve black-forest-labs/FLUX.1-dev --num-gpus 1 --webui --webui-port 2333

Launch Text-to-Video Service

sglang serve Wan-AI/Wan2.2-T2V-A14B-Diffusers --num-gpus 1 --webui --webui-port 2333

Launch Image-to-Image Service

sglang serve --model-path Qwen/Qwen-Image-Edit-2511 --num-gpus 1 --webui --webui-port 2333

Launch Image-to-Video Service

sglang serve Wan-AI/Wan2.2-TI2V-5B-Diffusers --num-gpus 1 --webui --webui-port 2333

Port Forwarding

Once the WebUI service is running, you need to use SSH port forwarding to securely access the remote service from your local machine.

In most cases: Your IDE (like VS Code, Cursor, etc.) can handle this automatically. Check your IDE's remote development or port forwarding features. Otherwise, execute this command manually.

ssh -L ${WEBUI_PORT}:localhost:${WEBUI_PORT} user_name@machine_name

Interface Instructions

You can view your model path and task name directly in the UI. We'd appreciate any feedback you'd like to share.

Once launched, access the interface at http://localhost:${WEBUI_PORT} in your browser.
