Stability AI

Stability AI is an AI company that develops open-source generative AI models for image, audio, video, and language, including the Stable Diffusion family of image generation models. The Stability AI developer platform provides REST APIs for text-to-image generation, image editing, image upscaling, image structure control, video generation, and 3D asset creation. All APIs are accessible at api.stability.ai using bearer token authentication.

    docs: Initiates an asynchronous video generation from a single input image. Returns a generation ID that can be used to
      poll for the completed video. The model produces a short animated sequence with realistic motion derived from the input
      image. Parameters control the strength of motion and conditioning.
