Stability AI Brief Overview
Stability AI (stability.ai) is a multimodal generative AI platform best known for the Stable Diffusion family of models. It focuses on helping creators, teams, and enterprises generate and edit media faster—especially images—while also offering pathways into video, audio, and 3D.
What makes Stability AI different from many “single-app” AI tools is the range of ways you can use it. If you want a straightforward workflow, you can use Stability’s web-based applications (such as DreamStudio or Stable Assistant) to generate images and apply edits. If you’re building a product, you can integrate Stability’s capabilities through the Stability AI Developer Platform (API). If you need maximum control or want to keep data in your own environment, Stability also supports self-hosting certain models under its licensing options.
Simple How-To-Use
Option A: Use a web app (fastest for beginners)
- Create an account through a Stability AI application (commonly DreamStudio or Stable Assistant).
- Choose an image generation workflow and select a model/tool (for example, a Stable Diffusion image model).
- Enter a text prompt describing what you want. Add details like style, lighting, subject, and aspect ratio for better results.
- Generate an image, then refine it using editing tools (remove background, inpaint/outpaint, erase objects, upscale, etc.).
- Download the final output and use it in your design, marketing, content, or product workflow.
Option B: Use the Developer Platform API (best for teams and developers)
- Create a developer account, generate an API key, and add credits.
- Call the REST API for text-to-image, editing, upscaling, and other endpoints.
- Monitor credit usage from your billing dashboard and optimize settings/model choice to control cost.
Option C: Self-host (best for control, privacy, and customization)
- Select the appropriate license, obtain the model, and deploy it in your own environment.
- Connect it to internal tools, pipelines, or production workflows as needed.
Stability AI Key Features and Functions
- Text-to-image generation using the Stable Diffusion model family (including Stable Diffusion 3.5 variants such as Large, Turbo, and Medium).
- Image editing services for professional workflows, including:
- Erase objects
- Inpaint and outpaint
- Remove background
- Search and recolor / search and replace
- Replace background and relight
- Upscaling tools (multiple modes designed for speed vs. quality).
- Control tools that help guide generations from sketches or structural/style constraints.
- Beyond images: Stability AI also offers models and tooling related to video (e.g., Stable Video Diffusion) and audio (Stable Audio offerings), depending on the product and deployment method.
Pricing
Stability AI pricing commonly revolves around credits and (for some apps) subscriptions:
- Developer Platform / API credits: Pricing is credit-based, with 1 credit typically equal to $0.01. New accounts may include free credits, and additional credits can be purchased (for example, $1 for 100 credits).
- Stable Assistant subscription plans (includes a free 3-day trial):
- Standard: $9/month (900 credits)
- Pro: $19/month (1,900 credits)
- Plus: $49/month (5,500 credits)
- Premium: $99/month (12,000 credits)
- Annual billing options are also available (e.g., Standard at $90/year).
Example usage: an image generation can deduct 6.5 credits, and a chat message can deduct 0.1 credit.
- Credit separation across products: Platform API and DreamStudio credits are designed to be cross-compatible, while Stable Assistant credits are separate from Platform/DreamStudio credits.
- Self-host licensing: The Community license is free for individuals and organizations under $1M annual revenue, while Enterprise licensing is offered with custom pricing for larger organizations.
