Stability AI

Stability AI is a company focused on developing open-source AI models, best known for its image generation model Stable Diffusion, dedicated to providing tools and technologies for multimodal content generation—images, video, audio, and 3D.

Its core product is Stable Diffusion, an open-source text-to-image generation model. The company also provides the Stable Assistant creative suite around this model and extends to tools for generating and editing video, audio, and 3D content.

Stability AI offers a free Community License for non-commercial use and small businesses with annual revenue under a threshold. For commercial use and larger organizations, you need an appropriate Enterprise license or pay via API services.

Usage rights depend on the chosen licensing. Free Community licenses typically restrict commercial use, while Enterprise licenses provide explicit commercial rights. Users should choose the licensing that fits their needs.

You can integrate via the provided API for cloud deployment, and also download the models to self-host in your own environment. The exact method depends on your tech stack and requirements.

Primarily supports text-to-image generation, with additional capabilities for image editing, image-to-video, audio generation, and generating 3D models from a single image.

For local deployment, you typically need a reasonably capable GPU (e.g., NVIDIA) with sufficient VRAM. Requirements vary by model; some optimized models can run on consumer hardware. Cloud API usage mainly depends on network connectivity.

Stability AI's core model, Stable Diffusion, is open source, supporting local deployment and deep customization with strong controllability; Midjourney is a closed-source online service accessed mainly via Discord, known for ease of use and artistic style, with a paid subscription.

According to some technical docs, support for Chinese natural language prompts may be limited; it's recommended to use English prompts for more accurate results.
