Product overview
Stability AI develops multimodal generative models for images, video, audio, and 3D content from London. Founded in 2019, the company went through leadership changes in 2024: founder Emad Mostaque resigned, and CEO Prem Akkaraju joined in June alongside executive chairman Sean Parker. A mid-2024 recapitalization forgave over $100 million in debt and brought approximately $80 million in new funding. Stable Diffusion is the flagship product. Version 3.5 comes in Large (8B parameters), Medium, and Turbo variants. A Community License allows free use for individuals and organizations under $1 million in annual revenue; larger organizations require an Enterprise License. The company also offers Stable Video Diffusion, Stable Audio 2.0, Stable Fast 3D, and StableLM for text generation. Over 150 million Stable Diffusion downloads have been recorded across all versions. Models are accessible through the Platform API (credit-based, starting at approximately $0.04 per image), DreamStudio web interface, Hugging Face, and self-hosted deployment. In 2025, the company signed partnerships with Electronic Arts, Universal Music Group, and Warner Music Group. WPP made a corporate investment in March 2025.
