NMKD Stable Diffusion GUI vs Stable Diffusion

NMKD Stable Diffusion GUI runs text-to-image and image-to-image generation locally on your Windows PC using your own GPU. The itch.io download bundles dependencies so you skip manual Python setup, and version 1.11.0 ships with a Stable Diffusion 1.5 model in a 3.3 GB package or a 1.5 GB build if you bring your own checkpoints.

Unlike browser-based generators that queue jobs on remote servers, NMKD keeps everything on your hardware with no data collection. It adds LoRA training on 8 GB GPUs, InstructPix2Pix editing, RealESRGAN upscaling, and CodeFormer or GFPGAN face restoration in one desktop app. The author reports sub-2-second generations on an RTX 3090 and under one second on an RTX 4090.

Windows hobbyists, game texture artists, and creators who want uncensored local control are the main audience. Built-in prompt queues, tileable output for game assets, custom VAE and checkpoint loading, and a malware scan on downloaded models make it a full workstation tool rather than a quick online demo.

Stable Diffusion is Stability AI's open-weight image generation model family, now centered on Stable Diffusion 3.5 with Large, Turbo, and Medium variants. The stability.ai site also hosts related media models for image editing, video, audio, and 3D, plus Brand Studio for on-brand creative production. You can self-host the weights, call the Stability AI API, or use web apps such as Stable Assistant.

Most closed image APIs only serve generations through a hosted endpoint. Stability AI still publishes model weights you can deploy on your own infrastructure while also selling managed tools like Brand Studio with brand-specific training and precision editing. Stable Diffusion 3.5 Large targets 1 megapixel professional output, Turbo generates in four steps, and Medium is tuned for consumer hardware.

It fits creative teams, game studios, and developers who want both open models and enterprise controls. Brand Studio lists a free trial with 1,000 credits, a Creator plan at $19 per month with 2,000 credits, and a Core plan at $50 per month with 5,000 credits. Stability AI reports partnerships with EA, Universal Music Group, and HubSpot on its homepage.
