How to Use ImagineArt 1.5 Pro: Native 4K Specs, Credit Cost and Prompts
A practical guide to ImagineArt 1.5 Pro on VdoBloom: a flat 12 credits per image, native 4K on all 10 aspect ratios up to 6592x2200, how to prompt it, and when a cheaper model wins.
ImagineArt 1.5 Pro is VdoBloom’s native-4K text-to-image model: it costs a flat 12 credits per image (about $0.60 at the Lite rate), and every aspect ratio renders at 4K or larger — 4096×4096 for a square, 5120×2880 for 16:9, and 6592×2200 for the 3:1 banner. There is no resolution dropdown to get wrong and no quality tier to upsell you; you pick an aspect ratio, you write a prompt, and you get one very large image. It runs through Runware on the model id imagineart:1.5-pro@0, and it went live on VdoBloom in December 2025.
What it is actually best at
Three jobs, in order of how clearly it wins them.
Print-size and poster-size output without an upscaling step. Most image models in the roster top out at 1K or 2K and expect you to enlarge afterwards. ImagineArt 1.5 Pro generates at 4K natively, so the texture in skin, fabric, foliage and metal is generated detail rather than invented detail. A 4096Ă—4096 square is roughly a 13-inch print at 300 DPI with no interpolation.
Text and label placement inside a generated scene. The model is tuned for accurate text rendering and colour placement, and the extra pixels genuinely help: small glyphs have more room to resolve, so signage, packaging copy and posters survive better than they do at 1K. It is not the single best typography model on the platform — see the comparison further down — but it is the best one that also hands you 4K in one pass.
Ultra-wide and ultra-tall compositions. The 3:1 and 1:3 ratios come out at 6592Ă—2200 and 2200Ă—6592, and 21:9 lands at 5760Ă—2472. Those are website hero banners and tall editorial strips at full resolution, not crops out of a square.
Real specs and credit cost
Cost is flat. Every row below is 12 credits. At the Lite plan rate of $15 for 300 credits, one credit is $0.05, so every image costs the same $0.60 no matter which shape you pick — which means the widest ratios are simply better value per pixel.
| Aspect ratio | Output pixels | Megapixels | Credits | Cost |
|---|---|---|---|---|
| 1:1 | 4096 Ă— 4096 | 16.8 MP | 12 | $0.60 |
| 16:9 | 5120 Ă— 2880 | 14.7 MP | 12 | $0.60 |
| 9:16 | 2880 Ă— 5120 | 14.7 MP | 12 | $0.60 |
| 4:3 | 4448 Ă— 3328 | 14.8 MP | 12 | $0.60 |
| 3:4 | 3328 Ă— 4448 | 14.8 MP | 12 | $0.60 |
| 3:2 | 4608 Ă— 3072 | 14.2 MP | 12 | $0.60 |
| 2:3 | 3072 Ă— 4608 | 14.2 MP | 12 | $0.60 |
| 21:9 | 5760 Ă— 2472 | 14.2 MP | 12 | $0.60 |
| 3:1 | 6592 Ă— 2200 | 14.5 MP | 12 | $0.60 |
| 1:3 | 2200 Ă— 6592 | 14.5 MP | 12 | $0.60 |
Ten free signup credits will not cover a single image here, so treat 1.5 Pro as a paid-plan tool. The 10 credits a new account receives go further on the cheap end of the roster, and one-time credit packs start at $2.49 for 75 credits that never expire, which is six ImagineArt 1.5 Pro renders. Full plan maths lives on the pricing page.
Two limits to know before you start
It is text-to-image only. ImagineArt 1.5 Pro does not appear in the image-editing model list, so it accepts no reference images, no style images and no masks. If your job starts from a photo you already have, you are in the wrong tab — go to image editing and pick a model that takes reference inputs.
There is no seed control. The generation call sends the prompt and the resolved width and height, nothing else. You cannot lock a seed to reproduce an image exactly, so treat every run as a fresh draw and save the ones you like immediately. Failed generations are refunded automatically, so a timeout does not cost you the 12 credits.
How to prompt it well
Because there is no reference image and no seed, the prompt carries all of the control. Four habits that pay off:
- Lead with the subject and the shot, not the mood. Open with what is in frame and how it is framed — close-up, three-quarter portrait, wide establishing shot — then add lighting, then style. Adjective-first prompts drift.
- Quote your text verbatim. Write the exact words you want rendered inside quotation marks and say where they sit: on the bottle label, across the top third, on the wooden sign. Naming the placement matters more than naming the font.
- Spend words on the material, not on the adjective stack. At 4K the model has pixels to show brushed aluminium, condensation, linen weave or matte cardstock. Saying which material a surface is gives the detail somewhere to go.
- Match the ratio to the composition in words. If you choose 3:1, say it is a wide banner with the subject at left and clear space at right. The model fills what you describe; an unfilled ultra-wide frame reads as empty.
A worked example
Say you need a hero banner for a coffee brand. Pick 3:1, which gives you 6592×2200. Prompt something like: a wide banner composition, a matte black espresso tin standing left of centre on a raw concrete counter, condensation on the steel portafilter beside it, the words “SLOW ROAST” printed in clean sans-serif on the tin, warm directional morning light from the right, deep shadow falling left, shallow depth of field, empty concrete on the right third for headline copy.
That prompt does four things at once: it names the frame, it reserves negative space for the text your designer will add later, it quotes the only words the model has to render, and it gives two surfaces (concrete, brushed steel) for the 4K detail to land on. Cost: 12 credits, $0.60. Three variations to choose from: 36 credits, $1.80.
When to pick a different model
| If you need | Better pick | Credits |
|---|---|---|
| The same look at 2K for half the price | ImagineArt 1.5 | 6 |
| A 1K or 2K choice and richer colour | ImagineArt 2.0 | 10 |
| Cheapest usable text-to-image | Z-image Turbo | 2 |
| 4K on a tight budget | WAN 2.7 Image | 4 |
| Best-in-roster text and lettering | Seedream 4.5 Text-to-Image | 7 |
| Editing a photo you already have | Any model on the edit tab | from 4 |
The honest summary: if 2K is enough, ImagineArt 1.5 does the same job for 6 credits and you should use it. The 12-credit version earns its price only when the output is genuinely going somewhere large — print, a full-bleed banner, or a crop you intend to take out of a much bigger frame.
You can compare it side by side with the rest of the roster in the multi-model image generator, read the text-rendering breakdown in our guide to the best model for text in images, or just open image generation and pick ImagineArt 1.5 Pro from the family selector.
Frequently asked questions
How much does one ImagineArt 1.5 Pro image cost?
A flat 12 credits, every aspect ratio, every time. At the Lite plan rate of $15 for 300 credits that is $0.60 per image. There is no cheaper tier within the model.
Can I use my own photo as a reference?
No. ImagineArt 1.5 Pro is text-to-image only on VdoBloom and takes no image inputs. For reference-guided work use the edit tab, where models accept between one and fourteen input images depending on which you choose.
What is the largest image it can produce?
6592Ă—2200 on the 3:1 ratio, or 2200Ă—6592 on 1:3. The largest square is 4096Ă—4096 and the largest 16:9 is 5120Ă—2880.
What is the difference between ImagineArt 1.5 and 1.5 Pro?
Resolution and price. 1.5 renders at 2K (2048Ă—2048 square) for 6 credits; 1.5 Pro renders the same ratios at 4K for 12, and adds a 21:9 option that 1.5 does not have.
Do I get charged if the generation fails?
No. Credits are deducted up front and automatically refunded if the generation does not return an image.
Are the images watermark-free?
On any paid plan, yes, and they come with commercial rights. Free-tier output carries a watermark.
