Stable Diffusion: Key Features, Pricing, & Alternatives in 2025

What is Stable Diffusion?

Founder/CEO: Emad Mostaque, Prem Akkaraju (CEO)
Launch Date: August 2022
Technology: Core architecture is a latent diffusion model with U‑Net and CLIP encoder, trained on LAION-5B image-text data. Newer versions (SDXL, SD 3.5) employ Diffusion Transformer (DiT) structures and scaled parameters (up to ~8B) for better detail and text rendering
Use Cases: Generates images from text prompts, performs inpainting/outpainting, transforms sketches to images, prototyping, concept art, visual design, and video/animation generation via extensions like Deforum or Stable Video Diffusion

Stable Diffusion is an open-source AI text-to-image generation platform that generates high-quality images from text prompts. Stability AI developed it, which uses a latent diffusion technique to create magnificent images with fine details and artistic coherence. Unlike many proprietary models, Stable Diffusion can run locally or via cloud services, giving consumers more freedom, customization, and anonymity. Users can use the platform to make images, upscale them, restore faces, and do other things without needing to code. It offers advanced features like prompt weighting, image-to-image generation, and negative prompts to offer more control. Stable Diffusion is ideal for artists, designers, academics, and developers. It has driven a wide range of creative projects and AI tools, democratizing access to generative art and making text-to-image AI publicly available.
