Why GPT Image on AI Image Tools
Text inside the picture
Signage, packaging, book covers, UI mockups. Put the exact words in quotes and these are the models most likely to render them as letters rather than as shapes that resemble letters.
2.5 follows longer instructions
The newer generation holds on to more of a complex prompt. If a detailed instruction keeps getting partly ignored on the cheaper tiers, this is the one to try.
Real 4K when you need it
The 4K tiers cost more because they produce more. Our measured output at the 2K tier was already 2048 × 2048 PNG.
Reads several reference images
Up to 16 input images, which makes these tiers usable in Virtual Try-On and any other multi-image workflow.
Every image model in one place
Pick any of these from the Model menu above; the price is shown before you generate. Each name links to what that model is good at. Compare every tier.

How to use GPT Image
- Step 1
Start on GPT Image 2 · 2K
Seven credits. Enough to find out whether the model understands the brief.
- Step 2
Move up only for a reason
2.5 for a long instruction it keeps dropping; 4K for print or heavy cropping. Otherwise the cheaper tier is the same picture.
- Step 3
Check the lettering at full size
Text is the reason to use these models and also the first thing to go wrong. Zoom in before you download.
How to write a prompt for GPT Image
Quote the exact words
"a sign reading 'OPEN DAILY 7-3'". Unquoted text gets paraphrased or invented.
Keep the copy short
A few words render reliably. A paragraph does not, on any model here.
Say where the text sits
"Centred on the awning", "along the bottom edge". Placement is part of the picture, not an afterthought.
Spend the tier on the right thing
4K buys pixels, not comprehension. If the model is misreading the brief, go to 2.5 rather than to 4K.

GPT Image: frequently asked questions
What is the difference between GPT Image 2 and 2.5?
2.5 is the newer generation and holds on to more of a long instruction. Both are offered at 2K and 4K. Version 2 at 2K costs 7 credits; 2.5 at 2K costs 13.
Which tier should I start on?
GPT Image 2 · 2K at 7 credits. Move to 2.5 when the model keeps dropping part of your instruction, and to 4K only when you need the pixels for print or cropping.
Are these the best models here for text in an image?
Yes, alongside Seedream for poster layouts. Put the exact words in quotes and keep them short.
Is 4K worth double the credits?
The 4K tiers are on paid plans. Even then, only if you need the resolution. The picture is the same picture; you are paying for pixels. For a larger file from a cheaper tier, run the 2K output through the Image Upscaler for 2 credits.
What happens if a run fails?
You are only charged when an image comes back. A failed or timed-out run costs nothing.
