Leverage your private Stable Diffusion API with ComfyUI or Automatic1111 using an RTX 3090 Blib (or faster) from Trooper.AI.

Want to create your own ComfyUI or Automatic1111 API for image generation with Stable Diffusion XL — fully controlled, ultra-fast, and hosted on a 3090 or higher blib here at Trooper.AI?
That’s exactly what we enable. Instead of relying on external APIs, you can deploy, configure, and run your private AI image API in the EU at minimal cost and maximum performance.
Whether you’re integrating AI image generation into your software, building a creative platform, or running automated workflows — our Trooper.AI GPU servers are designed for developers who want to own their API and scale on demand.

With a dedicated RTX 3090 or stronger GPU, you can launch your ComfyUI or Automatic1111 backend and expose it as a custom REST API.
Your IT team can process Stable Diffusion prompts directly from your applications and return images in seconds.
💡 No shared queues, no throttling, full admin control – your blib, your AI, your API.

View some example images generated with Stable Diffusion XL API from ComfyUI or Automatic1111. These example are simple prompts and renders of SDXL Base checkpoint. We recommend using newer checkpoints like Juggernaut-XL-v9.
With Trooper.AI, you’re not just running a model — you’re building your own creative infrastructure.
Host Automatic1111 for instant prompt-to-image rendering, or deploy ComfyUI for advanced graph-based automation.
💬 Example: Run Stable Diffusion XL on your own REST API endpoint, integrate it into your SaaS or web app, and respond to user prompts with instant image generation.

Choosing the right Trooper.AI blib for Stable Diffusion XL doesn’t have to be expensive. We offer options to fit your budget, from the affordable A4000 to powerful 4090 configurations.
For most users, a 3090 blib offers the best balance of speed and cost, generating images in 5-12 seconds.
To get the most value, start with a lower-tier option and scale up if you need faster performance or higher resolution. Consider your typical image complexity and desired speed when making your choice.
