About Grok Imagine
Grok Imagine is the AI image generation feature built into Grok, xAI's conversational AI assistant. Available directly on X (formerly Twitter) and the Grok app, it lets users generate images from text prompts using xAI's proprietary Aurora image model — no separate account or tool required.
Grok Imagine is free to use for all X users up to a monthly generation limit. Basic image creation from text prompts requires no paid subscription, making it one of the most accessible AI image generators available today. Free-tier users get standard quality outputs with a cap of 10 generations per month.
Unlike standalone image generators, Grok AI Imagine is natively integrated into the Grok chat interface. You can describe an image in plain conversation and Grok will generate it inline — combining the context of a conversation with image creation in one unified experience.
SuperGrok Pro subscribers gain access to Grok's video generation capabilities powered by xAI's Aurora model. Free-tier users do not have access to video generation. This makes SuperGrok the go-to plan for creators who need both still images and short AI-generated video clips.
Getting Started
Getting started with Grok AI Imagine is straightforward if you have an X account. Here's the complete flow from access to your first generated image.
Open X (Twitter) and navigate to Grok in the sidebar, or download the standalone Grok app. Sign in with your X account. Grok Imagine is available to all X users, including free accounts, within the Grok chat interface.
In the Grok chat window, describe the image you want to create. You can either use the dedicated image generation command ("generate an image of...") or simply describe what you want and Grok will recognize the intent. Be specific: include subject, style, lighting, and mood.
Grok Imagine will produce your image within seconds. Review the result in the chat. If the output doesn't match your vision, refine the prompt and regenerate. Each refinement counts against your monthly free limit, so craft precise prompts to get the best result on fewer attempts.
Once you hit the free-tier limit of 10 generations per month, upgrade to SuperGrok Pro for unlimited image generation, HD quality, video creation, and Spicy Mode access. SuperGrok is xAI's premium subscription that unlocks the full Grok Imagine experience.
Prompt Templates
Copy any of these Grok Imagine prompts and paste them directly into the Grok chat to generate images. These examples cover every major style: realistic photography, anime, concept art, spicy mode, and video prompts for SuperGrok subscribers.
A strong Grok Imagine prompt for photorealistic human portraits.
Prompt
A hyperrealistic close-up portrait of a woman with piercing green eyes, natural freckles, golden hour backlight catching her loose auburn hair. Shot on 85mm f/1.4 lens, shallow depth of field, cinematic color grading, no text, no watermark.
Specify 'hyperrealistic' explicitly — Grok Imagine responds well to photography-style technical instructions.
One of the most popular Grok AI Imagine prompt styles for anime fans.
Prompt
Anime-style illustration of a silver-haired warrior girl in a midnight battlefield, glowing blue eyes, tattered dark armor, crescent moon rising behind her, sakura petals falling in the wind. Detailed linework, Studio Ghibli-inspired color palette, dramatic upward angle.
Reference specific anime studios or shows to guide Grok Imagine toward a consistent visual style.
A sweeping concept art prompt perfect for wallpapers and world-building with Grok AI.
Prompt
Aerial view of a rain-soaked neon cyberpunk megacity at 3 AM. Purple and cyan neon signs reflect off wet streets, flying taxis weave between skyscrapers, holographic billboards visible through volumetric smog. Ultra-wide cinematic composition, no text overlays, 8K detail.
Add specific color palette instructions ("amber and indigo only") to differentiate your Grok Imagine output from generic cyberpunk.
Epic fantasy landscape prompt for Grok Imagine — great for book covers and concept art.
Prompt
A sweeping fantasy landscape: a floating island kingdom above the clouds, ancient stone temples draped with vines and glowing runes, waterfalls cascading into the sky below. Dramatic sunset with twin moons visible, painterly illustration style, rich warm palette, no text.
Try adding 'matte painting style' for a more refined, cinematic look in your Grok Imagine output.
For SuperGrok Pro users with Spicy Mode unlocked. Tasteful artistic content.
Prompt
A tasteful fine-art nude study of a sculpted figure reclining on draped silk, classical oil painting style, Rembrandt lighting, museum-quality composition, no explicit content, artistic and dignified.
Spicy Mode requires SuperGrok Pro. Keep prompts artistic rather than explicit to stay within xAI's content policy.
Clean product render prompt for Grok AI Imagine — ideal for e-commerce and mockups.
Prompt
Hyperrealistic product render of a matte obsidian luxury perfume bottle on a black marble surface. Studio lighting with soft top highlights and side rim light, macro lens detail on glass facets, minimal composition, generous white negative space, no text, no watermark.
Replace the product description and surface material to adapt this Grok Imagine prompt to any product.
Video generation prompt for SuperGrok Pro subscribers using Grok Imagine's Aurora video model.
Prompt
Slow-motion close-up of an ocean wave crashing on dark volcanic rock. Sunlight fractures through the crest of the wave, foam and spray suspended in mid-air. Shot at 120fps, cinematic color grading, no text, natural sound ambience.
Video generation is a SuperGrok Pro exclusive. Short, action-focused prompts produce the most consistent video results.
Retro-inspired poster prompt — one of Grok AI Imagine's strongest graphic design use cases.
Prompt
A 1960s-style vintage travel poster for a fictional island called 'Isle Azura'. Bold flat graphic style, limited palette of coral, ivory, and teal. Stylized palm tree silhouettes, retro hand-lettered title treatment as visual texture, starburst border, balanced poster composition.
Change the decade and color palette to shift the visual language — '1930s, art deco, gold and black' works beautifully.
Ghibli-inspired landscape prompt for Grok Imagine anime mode.
Prompt
A serene anime landscape of a hillside meadow in midsummer, tall wildflowers swaying in the breeze, a lone girl sitting beneath an ancient oak tree reading a book. Soft watercolor sky, Studio Ghibli art direction, golden afternoon light, no text.
Grok AI Imagine handles Studio Ghibli-style prompts very well — specify 'cel-shaded' or 'watercolor' for variation.
Documentary-style street photography prompt for Grok Imagine realism.
Prompt
A candid street photography shot in a rainy Tokyo alley at dusk. A lone figure with an umbrella walks past steaming ramen stalls, neon signs softly blurred in the background. Fujifilm film simulation, 35mm f/2 lens, natural grain, documentary composition, no text.
Adding a specific camera brand or film simulation (Fujifilm, Kodak Portra) significantly improves Grok Imagine's photorealistic outputs.
Pricing & Limits
Understand the difference between the Grok Imagine free tier and SuperGrok Pro. Is Grok Imagine free? Yes — up to a point. Here's the full breakdown of what each plan includes.
| Feature | Free | SuperGrok Pro |

Pricing and limits are set by xAI and may change. Verify current plans at x.ai/grok.
Yes — Grok Imagine is free up to 10 image generations per month for all X users. After hitting the free limit, users either wait for the monthly reset or upgrade to SuperGrok Pro for unlimited access. This answers the common question "is grok imagine free" — it is, but with limits.
Grok Imagine introduced generation limits after its initial launch period. xAI moved from an unlimited free model to a capped free tier and a paid SuperGrok Pro plan. Users who remember unlimited free generations often ask "why is grok imagine not free anymore" — the answer is infrastructure cost and sustainable monetization.
SuperGrok is xAI's premium subscription tier. It unlocks unlimited image generation, HD quality, video generation, Spicy Mode, and API access. For heavy users, artists, and developers, SuperGrok Pro is the recommended plan. Pricing is set by xAI — check x.ai/grok for the current rate.
API
The Grok Imagine API allows SuperGrok Pro subscribers to generate images programmatically using xAI's Aurora model. Here's how to integrate the Grok API into your own applications.
Access to the Grok Imagine API requires a SuperGrok Pro subscription and an xAI API key. Free-tier Grok users cannot access the API. Once you have a key, you can call the Grok API endpoint to generate images programmatically from any server-side environment.
Send a POST request to the xAI image generation endpoint with your prompt and parameters. The API returns image data that can be decoded and stored or served directly in your application.

Content Policy
Understanding Grok Imagine's content moderation system is essential for knowing what you can and can't generate — and how SuperGrok Pro's Spicy Mode changes the rules.
All free-tier Grok Imagine users operate in moderated mode. This means the system filters prompts and outputs for explicit sexual content, graphic violence, hate speech, and other policy violations. Grok Imagine moderated mode follows xAI's standard content guidelines, which are similar to other mainstream AI image generators. You can generate artistic nudity-adjacent content in some cases, but the system will block explicit requests.
Grok Imagine Spicy Mode is available to SuperGrok Pro subscribers and unlocks more permissive content generation, including tasteful adult-oriented imagery. Spicy Mode is not a bypass for all content restrictions — xAI's absolute limits (CSAM, real person non-consensual, illegal content) still apply. Spicy Mode simply relaxes the default conservative filters for adult users who have agreed to xAI's terms for this feature.
In both moderated and Spicy Mode, Grok Imagine will refuse: content sexualizing minors (CSAM), non-consensual intimate imagery of real people, detailed instructions for violence or harm embedded in prompts, and content that violates xAI's core terms of service. These restrictions apply universally regardless of subscription tier.
