How It Works
Generate AI Images in 4 Simple Steps
Craft Your Prompt
Describe the image — subject, style, lighting, composition, and any text you want rendered. You have up to 4,000 characters, so be specific.
Choose Settings
Pick an aspect ratio, set how many images to generate, and switch on Pro Mode when a prompt deserves the extra fidelity.
Generate
Hit generate and Grok Imagine turns the prompt into finished images in seconds. Credits are charged per run, and refunded automatically if one fails.
Download & Use
Compare the variations, keep the ones that work, and download them at full quality for commercial or personal use.
Why Choose Grok Imagine
Fast, Accurate AI Image Generation — Free to Start
Fast Generation
Grok Imagine returns finished images in seconds, so you iterate on a prompt instead of queueing behind it. Run up to four variations at once and keep the ones that land.
Precise Prompt Understanding
Prompts run up to 4,000 characters. Grok Imagine holds mood, lighting, composition and embedded text together instead of dropping the details you spelled out.
Five Aspect Ratios
1:1, 16:9, 9:16, 3:2 and 2:3 — sized for Instagram, YouTube thumbnails, TikTok and print. Pick the ratio before you generate so nothing gets cropped afterwards.
Text and Image Prompts
Start from a description, or upload up to five reference images and let Grok Imagine transform them. Same workspace, same credits, no re-uploading between runs.
Versatile Creative Styles
Photorealistic portraits, anime, watercolour, concept art, editorial illustration — name the style in your prompt and Grok Imagine follows it. Pro Mode adds fidelity when a draft is worth finishing.

Grok Imagine Image Generator FAQ
Everything You Need to Know About Grok Imagine
Grok Imagine is xAI's Aurora-powered image model. Type a prompt describing the image you want, pick an aspect ratio, and it returns finished images in seconds. It handles both text-to-image and image-to-image, so you can start from a description or from up to five reference photos.
You get free credits as soon as you create an account here, plus more from the daily check-in, and no credit card is required. That matters because xAI has moved Grok Imagine on grok.com behind its paid SuperGrok tiers. Paid plans here are optional, for when you generate at volume.
Grok Imagine is built for speed and for rendering text inside an image, and it runs in the browser with no Discord setup. If you want a different trade-off, Nano Banana Pro, Flux 2 Pro, Imagen 4, GPT Image 1.5 and Seedream 4.5 are all in the same model picker — run one prompt through several and keep the best result.
Be specific. Name the style (photorealistic, anime, watercolour), the lighting (soft, dramatic, golden hour), the composition (close-up, wide shot, bird's eye) and the mood. Prompts can run to 4,000 characters, so there is room to describe exactly what you want.
Yes. Images you generate can be used commercially — websites, social campaigns, advertising, packaging and print. You keep the rights to what you create.
Grok Imagine supports five: 1:1 for Instagram, 16:9 for YouTube and desktop, 9:16 for TikTok and Stories, and 3:2 or 2:3 for photography-style framing. Other models in the picker add more, including 4:3, 4:5, 5:4 and 21:9.
Grok Imagine has no resolution selector — it returns one high-quality size per aspect ratio, with Pro Mode available for extra fidelity. If you need a specific output size, Nano Banana Pro in the same picker generates at 1K, 2K or 4K from the same prompt.
Yes. Put the words you want in quotes inside your prompt. Text rendering is one of Grok Imagine’s stronger areas — signs, labels, posters and logo mockups usually come back readable, though long passages still take a second pass.
Spicy is one of three generation modes — Normal, Fun and Spicy — in the Grok Imagine video generator. It loosens style restrictions for bolder, more expressive output. Here it is a dropdown next to the prompt box, not a setting you have to dig out of the X app.
Write one specific prompt rather than a vague one, generate four variations at once, then refine around whichever came closest. Naming the camera, lens or lighting usually does more than piling on adjectives.
Yes. Switch to image-to-image and upload up to five reference images, then describe the change you want — style transfer, a new background, a variation on an existing composition. The references stay attached across runs.
Photorealistic photography, digital art, anime and manga, oil painting, watercolour, concept art, pixel art, abstract, surreal, editorial illustration and 3D rendering. Describe the style in the prompt and the Aurora engine adapts to it.
