Grok Imagine is xAI's image and video generation capability built into Grok, available on grok.com, the Grok apps and X. It is free to start, generation was originally powered by xAI's autoregressive Aurora model announced in December 2024, and it is also exposed to developers through the xAI API.
Who builds it
Grok Imagine is built by xAI, the AI company behind the Grok chatbot. Rather than shipping as a separate destination site, image generation is folded directly into the same Grok experience users already know from chat — on grok.com, in the Grok mobile apps, and inside X — with a parallel path for developers who want direct API access through xAI's grok-imagine-image models rather than the consumer-facing Grok surfaces.
What it does
Grok Imagine generates images (and video) from a prompt, with xAI's own materials describing photorealistic rendering alongside more playful use cases such as portraits, artistic text and memes. Generation is supported up to 2K resolution, according to xAI's own product page, and text rendered legibly inside an image is supported as well. The xAI developer documentation and xAI's own product announcement both describe inpainting-style editing capability, so Grok Imagine is not limited to one-shot generation from a text prompt alone, and users can iterate on a result rather than regenerating it from scratch each time.
Pricing
Grok Imagine follows a freemium model: xAI's own Grok product page confirms a free tier is available, so a user can generate images without paying. No specific starting price for a paid tier with expanded limits is stated in xAI's own materials referenced here, so exact paid pricing should be checked directly on xAI's site. The free-first approach mirrors how xAI has rolled out Grok itself: broad access first, with paid tiers layered on for heavier or commercial usage.
Rights and provenance
Commercial use of Grok Imagine output is allowed but with limits, according to xAI's own Terms of Service, and those same terms confirm that ownership of generated output sits with the user rather than with xAI. That freemium-plus-commercial-rights combination, delivered inside a mainstream consumer product already used for chat and inside X itself, gives Grok Imagine a distribution advantage most standalone image generators do not have — a very large existing user base can try image generation without installing a new app or signing up for a new account, while developers who need programmatic access get the same underlying models through the xAI API. No provenance-watermarking claim, such as C2PA or SynthID-style labeling, appears in the facts available for Grok Imagine, so that aspect should be checked directly with xAI rather than assumed either way.
