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 --model-path black-forest-labs/FLUX.1-dev --num-gpus 1 --webui --webui-port 2333
Launch Text-to-Video Service
sglang serve --model-path 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 --model-path 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.
