Stability AI Erase API
Remove objects from an image by masking the area to erase and letting the AI fill in the background naturally.
Stability AI Fast Upscale API
Quickly increase image resolution with minimal processing time while maintaining image quality.
Stability AI Generate Core API
Generate images using Stable Image Core, a fast and affordable model for high-quality image generation.
Stability AI Generate SD3 API
Generate images using Stable Diffusion 3 and 3.5 models with advanced text-to-image and image-to-image capabilities.
Stability AI Generate Ultra API
Generate images using Stable Image Ultra, the highest quality model for state-of-the-art photorealistic and artistic image generation.
Stability AI Image to Video API
Generate short video clips from a single input image using the Stable Video Diffusion model. The API uses an asynchronous start-and-poll pattern.
Stability AI Inpaint API
Fill in masked regions of an image using AI-guided inpainting with text prompts to control what appears in the filled area.
Stability AI Outpaint API
Extend the boundaries of an image by generating new content that seamlessly continues the existing scene in any direction.
Stability AI Remove Background API
Automatically detect and remove the background from an image, isolating the foreground subject.
Stability AI Replace Background and Relight API
Replace the background of an image and adjust lighting conditions using AI-powered scene understanding.
Stability AI Search and Recolor API
Find specific objects within an image and recolor them using text descriptions of the target object and desired color.
Stability AI Search and Replace API
Find and replace specific objects within an image using text descriptions of what to search for and what to replace it with.
Stability AI Sketch API
Generate images from hand-drawn sketches or line drawings, guided by a text prompt to fill in details, colors, and textures.
Stability AI Structure API
Generate images guided by the structural composition of a reference image, preserving edges and layout while applying new content from a text prompt.
Stability AI Style API
Generate images that adopt the visual style of a reference image while following a text prompt for content direction.
