Private Image Generation Studio
ComfyUI in a box: a private design studio for on-brand imagery.
Your own generative design studio, delivered as an appliance. Built on ComfyUI, the open-source node-based workflow engine, and preloaded with curated models and ready-made templates, it lets designers turn sketches, references and prompts into prints, product concepts and campaign visuals, while your designs and your brand stay private.
- ComfyUI preinstalled and configured
- Templates for non-technical users
- Designs never train a public model
01The challenge
Your designs are your IP. Public image tools are not the place for them.
Uploading unreleased collections, prints or packaging to public image generators risks leaks and unclear rights. Designers still want the speed of generative tools. A private studio gives them that speed on hardware you own.
02Capabilities
What it does.
One-click templates
Prepared workflows for common jobs, so non-technical staff get results without touching nodes.
Sketch and reference control
Turn line sketches, mood images and existing products into guided renders.
Your brand, trained privately
Fine-tune style adapters on your own designs, on your own hardware.
Edit, extend and upscale
Inpainting, background replacement, variations and high-resolution upscaling.
Curated, licensed models
Models selected for quality and licence terms that suit commercial use.
03How it works
From question to answer, inside your walls.
ComfyUI, the open-source node-based engine for image and video generation, with curated open models and Logic Sonata templates, configured and supported on your appliance.

07FAQ
Questions about PAI-IMG.
Do designers need to learn ComfyUI?
No. Templates cover common jobs with a simple form. Technical artists can open the full node editor when they want more control.
