About Grok Imagine

Text and image-driven video generation from X.ai

Grok Imagine is a video generation model developed by X.ai, the AI division of X (formerly Twitter). Released in August 2025, it accepts text prompts alongside optional source images or source video as inputs, and produces video output at a configurable aspect ratio and duration. Pricing is usage-based at $0.05 per second of generated video, with a context window of 5,000 tokens for prompt input.

The model is designed for workflows that require video synthesis grounded in existing visual material, making it suitable for tasks like animating a still image, extending or transforming an existing video clip, or generating video from a descriptive prompt alone. Its support for both image-to-video and video-to-video input modes gives it flexibility across creative and production use cases. Grok Imagine is available through MindStudio without requiring separate API key management.

Capabilities

What Grok Imagine supports

Image-to-Video

Accepts a source image URL as input and animates it into a video clip. This allows a static image to serve as the visual starting point for generated video.

Video-to-Video

Takes an existing video URL as input and uses it as a reference for generating new or transformed video output. Useful for style transfer or video extension workflows.

Text Prompt Input

Supports a text prompt context window of up to 5,000 tokens to guide video generation. Prompts can describe scene content, motion, style, or other visual attributes.

Aspect Ratio Control

Allows users to select the output aspect ratio via a configurable input field. This enables targeting specific display formats such as landscape, portrait, or square.

Duration Control

Accepts a numeric duration input to specify the length of the generated video in seconds. Pricing is calculated at $0.05 per second of output.
