Grok Imagine Pro is xAI’s premium image model on VdoBloom, and it runs at a flat 10 credits per image — $0.50 at subscription rates — whether you render at 1K or 2K, across nine aspect ratios from 1:2 all the way to 2:1. It lives on the image editing side of the dashboard, where you attach a reference photo and describe the change you want. This guide covers what it is genuinely good at, its real settings, the exact credit cost, how to prompt it, and the specific moments when a cheaper or stricter model is the smarter pick.

What Grok Imagine Pro actually is

There are two Grok Imagine image models on VdoBloom. The standard one, listed simply as Grok Imagine, is a 5-credit image-to-image editor with five aspect ratios and a single reference image. Grok Imagine Pro is the upgraded tier: it adds a resolution control (1K or 2K), widens the aspect-ratio list to nine options including the extreme 1:2 and 2:1 panoramas, and carries a higher community rating — 4.3 against the standard model’s 4.2.

It is delivered through Runware and sits in the MODERATE content tier on VdoBloom’s labelling. That means it is more permissive than the STRICT-tier models such as Nano Banana and GPT Image, which refuse a great deal of swimwear, fitness and fashion work outright, but it is not the most flexible option in the catalog either. Explicit and illegal content stays blocked on every model, no exceptions.

Real specs and exact credit cost

Every number below comes from the live model configuration and the credit table, not from marketing copy. The dollar figures use the Lite plan rate, where $15 buys 300 credits, so one credit is $0.05.

Setting	Grok Imagine Pro	Grok Imagine (standard)
Credits per image	10 (flat, any resolution)	5
Cost per image	$0.50	$0.25
Resolutions	1K, 2K	Not selectable
Aspect ratios	1:1, 3:4, 4:3, 9:16, 16:9, 2:3, 3:2, 1:2, 2:1	1:1, 2:3, 3:2, 16:9, 9:16
Reference images	Supported (picker copy describes one reference image)	1
Community rating	4.3	4.2
Content tier	MODERATE	MODERATE
Where it lives	Image editing tab	Image editing tab

The flat pricing is the single most useful fact here. Most premium image models on the platform charge more for higher resolution — Qwen Image 3.0 Pro Edit costs 6 credits at 1K and 7 at 2K, for instance. Grok Imagine Pro does not. If you are paying 10 credits either way, there is no reason to render at 1K unless you specifically want the smaller file.

How it compares on price to the other editors

Image editor	Credits	Dollar cost	Best for
Z-image Turbo	2	$0.10	Fast throwaway drafts
WAN 2.7 Image	4	$0.20	Multi-reference edits, up to 4K
Grok Imagine	5	$0.25	Quick single-image edits
Qwen Image 3.0 Edit	5	$0.25	Cheap 1K/2K editing
Seedream 4.5 Edit	7	$0.35	Stylised commercial looks
Grok Imagine Pro	10	$0.50	Wide-ratio, 2K reference edits
Kling IMAGE O1	14	$0.70	High-control multi-image composition
Nano Banana Pro	18	$0.90	Prompt-following accuracy, STRICT tier

Grok Imagine Pro sits in the upper-middle of that range. It is twice the price of the standard Grok model and roughly half the price of Nano Banana Pro.

How to prompt it well

Grok Imagine Pro is an editor first, so the prompt is an instruction about a change, not a description of a scene from scratch. Three habits improve results reliably.

Name what stays, not just what changes. Instead of asking for a new background, write the whole sentence: keep the subject, pose, lighting direction and wardrobe exactly as they are, replace only the background with an overcast beach at golden hour. Models drift on the parts of the frame you do not mention.

Match the aspect ratio to the crop you actually need. Because the nine ratios include 1:2 and 2:1, you can generate a banner or a tall poster natively instead of rendering 16:9 and cropping away half the pixels. Set the ratio before you generate, not afterwards.

Use concrete photographic language. Terms such as 85mm portrait lens, soft window light from camera left, shallow depth of field and matte skin texture steer the output far more than adjectives like beautiful or professional.

One responsibility note: if the reference image contains a real person, you must have that person’s consent before editing or publishing the result. That is a hard rule on VdoBloom, not a formality.

A worked example

Say you have one product shot of a ceramic mug on a kitchen counter and you need four marketplace variants. Open the editing tool at the image editor, pick Grok Imagine Pro, and attach the mug photo.

Set resolution to 2K — it costs the same 10 credits as 1K, so take the larger file.
Set the aspect ratio to 1:1 for the marketplace hero, and write: keep the mug, its handle angle and the steam exactly as they are; replace the counter with a dark walnut surface and add soft morning light from the left.
Regenerate with the ratio set to 2:1 for the listing banner, reusing the same prompt.
Regenerate at 9:16 for the story placement and at 4:3 for the catalog grid.

Four renders at 10 credits each is 40 credits, or $2.00. For comparison, the same four variants on Nano Banana Pro would cost 72 credits, or $3.60. New accounts get 10 free credits with no card, which is exactly one Grok Imagine Pro render to test the model before you commit.

When to pick a different model

Pick WAN 2.7 Image if you need to combine several reference photos or want a 4K output — it handles up to nine image inputs at 4 credits, and Grok Imagine Pro tops out at 2K.

Pick Qwen Image 3.0 Edit or Z-image Turbo when you are iterating on composition and expect to throw most renders away. At 5 and 2 credits respectively they make a twenty-attempt session affordable.

Pick Nano Banana Pro when literal prompt adherence matters more than price or content flexibility, such as reproducing exact text in a layout.

Pick a HOT-tier model — WAN 2.7 Image or Qwen — if your MODERATE-tier renders are getting refused on swimwear, dance or fitness subjects.

Pick a video model if the deliverable moves. Grok Imagine Pro produces stills only; its sibling Grok Imagine Video 1.5 Preview animates a finished still into a 1-to-15-second clip.

Full specs live on the Grok Imagine Pro model page, the cheaper sibling is documented at Grok Imagine, and credit-pack and subscription rates are on the pricing page. If you want to generate from a text prompt rather than edit an existing photo, use the image generator with one of the text-to-image models instead.

Frequently asked questions

How many credits does Grok Imagine Pro cost per image?

Ten credits per render, flat, at either 1K or 2K resolution. At the Lite subscription rate of $15 for 300 credits, that is $0.50 per image.

Does 2K cost more than 1K on Grok Imagine Pro?

No. The credit table charges the same 10 credits for both, which is unusual — most premium editors on the platform scale price with resolution. Render at 2K by default.

Can Grok Imagine Pro generate an image from text alone?

On VdoBloom it is listed in the image editing picker, so the normal workflow is a reference image plus an instruction. For pure text-to-image work, use the generate tool and one of the dedicated text-to-image models.

Is Grok Imagine Pro uncensored?

It carries the MODERATE content label, which is more permissive than the STRICT tier used by Nano Banana and GPT Image, but less flexible than the HOT-tier models. Explicit and illegal content is blocked on every model regardless of tier.

What aspect ratios does it support?

Nine: 1:1, 3:4, 4:3, 9:16, 16:9, 2:3, 3:2, 1:2 and 2:1. The 1:2 and 2:1 options are the widest and tallest native ratios among the Grok image models.

Do paid plans remove the watermark?

Yes. Paid plans download watermark-free with commercial rights, and one-time credit packs start at $2.49 for 75 credits that never expire.
