Grok Image

Grok Imagine is xAI's multimodal system for generating images and video. Its image capability produces photorealistic images with detailed textures, lighting, and facial detail, using the Aurora autoregressive mixture-of-experts model. The model supports up to 1024×1024 resolution and is built for quality that holds up in thumbnails, key frames, and social posts.

When you want photorealistic output at moderate resolution with strong detail-per-pixel efficiency, Grok Image is a strong choice. It fits volume workflows and testing while still delivering the coherence expected for professional short-form content.

Grok Imagine generates images with strong photorealism: detailed textures, natural lighting, and refined facial and object detail. Output is well suited for thumbnails, key frames, and social content that should feel polished and realistic. Skin, materials, and environments render with plausible detail and lighting.

The model supports up to 1024×1024 pixel resolution, fitting common social and web use cases. You get consistent quality across a range of prompts and styles. The resolution is sufficient for thumbnails, social feeds, and start frames that will be scaled or composed into video.

Grok Imagine covers both image and video in one ecosystem. Using the same system for key frames and clips can help keep style and character consistent when you combine Grok Image with Grok Video. Prompts and aesthetic choices in the image model tend to carry through to the video model, reducing the need for style matching in post.

xAI offers the Grok Imagine API for developers. The model is also available on X (Twitter) and partner platforms. Pricing and limits depend on whether you use the API, X subscriptions, or another partner integration.
