Stability AI is a London-based generative AI media company whose Stable Diffusion 3.5 (8.1 billion parameters) and Stable Audio 3 models power image, video, audio and 3D generation. Its models ship both open-weight for self-hosting and via a hosted API, alongside Brand Studio, a separate enterprise platform for brand-consistent visuals.
About Stability AI
Stability AI is a London-based artificial intelligence company specializing in open-source generative AI models for image, video, audio, and 3D content creation. Founded in 2019, the company gained prominence with the release of Stable Diffusion in August 2022, which became widely adopted by developers and creative professionals globally. CEO Prem Akkaraju, who joined in 2024, closed a $76 million Series B round in August 2026 backed by Universal Music Group, Sony Music Group, Warner Music Group, Electronic Arts, AMD Ventures and Pacific Alliance Ventures, bringing total funding to $232 million. The company offers open-source models under permissive licenses alongside Brand Studio, an enterprise platform for brand and marketing teams that succeeded Dream Studio this year. Differentiators include a multimodal stack spanning image, video, audio and 3D in one API, flexible deployment (self-hosted, cloud, or managed), and a licensing arrangement with major record labels that clears its audio models for commercial use. Stability AI's models and tools power production workflows for enterprises including Electronic Arts, HubSpot, Mercado Libre and digital marketing agency Huge, with the vendor reporting 25% higher click-through rates for ecommerce visuals generated through its platform.
Pricing
Brand Studio, Stability AI's brand-visual platform that replaced Dream Studio, offers a free trial (1,000 credits), Creator at $19/month (2,000 credits), and Core at $50/month (5,000 credits); unused monthly credits do not roll over. Enterprise pricing is custom with unlimited seats. Open-source models remain free to self-host under the Stability AI Community License for organizations under $1 million in annual revenue. The separate developer API on platform.stability.ai bills per model call on its own credit system rather than a flat subscription.
Key Features

- Enterprise-Grade Controls: Role-based access, brand governance, asset libraries, and custom workflow deployment for teams
- Flexible Deployment: Self-hosted open models, RESTful APIs, or cloud service integrations via AWS Bedrock and Azure AI Foundry
- Brand Studio Platform: Enterprise platform launched April 2026 to succeed Dream Studio, with Brand Central and Producer Mode training custom Brand ID models on a company's own photography and logos

Pros
- Open-source democratization with permissive licensing enables broad adoption and customization
- Multimodal capabilities (image, video, audio, 3D) in unified platform, rarely matched by competitors
- Enterprise deployment flexibility (self-host, API, cloud) with indemnification and compliance support
- Strong brand safety and production controls via Brand Studio, including custom Brand ID models trained on a company's own assets
- Proven enterprise adoption with measurable ROI (HubSpot, Mercado Libre, Stride Learning, and marketing agency Huge)
- High prompt adherence in Stable Diffusion 3.5 Large, competitive with or exceeding DALL-E 3 and Midjourney v6
Cons
- Brand Studio's paid tiers cap monthly credits that do not roll over, so heavy users must upgrade tiers or buy extra credit packs instead of paying purely by usage
- Mobile app support limited, no native iOS or Android applications, web-based only
- MMLU and code benchmark scores for image models not applicable (vision models use different metrics like prompt adherence and aesthetic scores)
- Competitive pressure from Flux, Midjourney, and DALL-E on image quality and speed tradeoffs
- Enterprise licensing and custom deployment require sales engagement, not self-service for large organizations
- Discontinued its standalone Stable Video API in July 2025, so dedicated video generation now needs the self-hosted route or a specialist competitor like Runway

Frequently Asked Questions
How much does Stability AI cost in 2026?
Brand Studio's Creator tier is $19 a month for 2,000 credits and Core is $50 a month for 5,000, after a free trial that covers the first 1,000; unused credits do not carry over. Enterprise plans use custom credit bundles and unlimited seats. The developer API is metered separately, charged per generation rather than as a subscription.
Does Stability AI have a free plan?
Yes: Brand Studio's free trial lets you generate before you need to subscribe, and Stability's Stable Diffusion and Stable Audio model weights can be downloaded and run at no cost under the Community License if your organization earns under $1 million a year. The hosted developer API on platform.stability.ai does not have a separate ongoing free tier.
What should you use instead of Stability AI?
For raw image quality and generation speed, Midjourney and Flux are the strongest alternatives; for enterprise brand teams, Adobe Firefly now competes directly with Brand Studio. Runway is the better pick for dedicated video work, since Stability no longer runs a standalone video API.
Is Stability AI better than Midjourney?
Not universally: Midjourney runs as a closed, subscription-only service optimized for aesthetic output through Discord and a web app, while Stability AI ships open-weight models you can self-host plus Brand Studio for brand-consistent enterprise work. Midjourney gets you to polished art faster; Stability AI gives you deployment control, an API, and brand governance.
How do you get started with Stability AI?
For the hosted route, create an account on platform.stability.ai, generate an API key, and call a generation endpoint directly; for brand work, sign up for Brand Studio's free trial and train a Brand ID model on your own photography and logos. Self-hosting the open-weight models means downloading the weights from Stability AI's Hugging Face or GitHub pages and running them under the Community License.
Top Alternatives
- Midjourney: Choose Midjourney when polished aesthetic output through a closed, subscription-only tool matters more than open access; Stability AI wins on deployment control and API flexibility.
- Flux: Choose Flux when you want a leaner open-weight model outside Stability's ecosystem; Stability AI wins on breadth, covering image, video, audio and 3D in one API.
- Adobe Firefly: Choose Adobe Firefly when your team already runs on Creative Cloud; Stability AI's Brand Studio wins as a standalone platform built around custom Brand ID models.
- Runway: Choose Runway when dedicated video generation is the priority; Stability retired its dedicated video API in 2025, leaving self-hosted open models as the main in-house option.
