AI image model · OpenAI
GPT Image 1.5, the draft model in classic photo formats.
The budget OpenAI model: classic photographic formats, the familiar GPT editing behaviour, at the lowest price on the site, in the same Studio composer as the current GPT Image 2.5 pair so a draft made here can be re-run on them without re-uploading anything. It is the only model in the catalog whose every tier is on the free plan.

Why this model
What GPT Image 1.5 is for.
Nothing behind a paywall
Its whole ladder, 1K at square, 3:2 and 2:3, sits on the free plan. It is the model a new account can simply spend the 10 credits it gets for signing up with Google or X on.
The classic OpenAI frames
It offers square, 3:2 and 2:3 because those are the sizes it truly draws. No silent letterboxing, no pretend 16:9 that arrives cropped.
Same editing DNA, smaller bill
The instruction-following that makes GPT Image 2 useful is here at 2 credits an image, fine for drafts, iterations and meme-speed work.
A cheap first pass
Explore ten ideas here, then re-run the winner on GPT Image 2 or Nano Banana Pro at a higher tier. The composer keeps your prompt when you switch.
Pricing

FAQ
Before you generate.
Last verified 21 Oct 2026
Is GPT Image 1.5 really free?
Yes, its single 1K tier costs 2 credits and is on the free plan, so the 10 credits for signing up with Google or X cover 5 images without a card or a subscription.
Why only 1:1, 3:2 and 2:3?
Those are the three sizes the model natively renders. Offering 16:9 would quietly hand back a 3:2, so ReelyArt lists what it can actually draw.
GPT Image 1.5 or GPT Image 2?
1.5 for volume and drafts, 2 for finals: it adds a true 2K tier, wide and tall formats, and stronger layout fidelity for one credit more at 1K.
Does it take reference images?
Up to eight, same as the rest of the catalog, or none at all for pure text-to-image.
Do I need an OpenAI account?
No. Generation runs on ReelyArt’s side; you only need a free ReelyArt account.
