Grok Imagine API exposes xAI's image generation and vision/understanding capabilities via a web API, allowing developers to generate images from text prompts, analyze and answer questions about images, and integrate multimodal reasoning into applications. It supports selection of different Grok image and vision models, configurable parameters for prompts and outputs, file uploads and URL-based image inputs, and streaming where supported. The API is commonly accessed via API keys and has multiple community SDKs and unofficial wrappers (Python, .NET, Swift) that provide conversation management, streaming responses, and tool integrations to simplify embedding Grok's image and vision features into production services.
