GPT Image-1.5
GPT Image 1.5 is OpenAI's mid-tier text to image model, available in FluxoKit's browser studio without an OpenAI account. It keeps the family's instruction-following and text rendering at 4 credits per image, which makes it the volume tier for drafts and ad variants on plans starting at $14 per month.

Real generations with GPT Image-1.5
Overview
GPT Image 1.5 sits between GPT Image 1 and GPT Image 2 in OpenAI's image family, and FluxoKit runs it in the browser with credit pricing instead of an OpenAI billing account. Same prompt language as its siblings, noticeably lower cost per attempt: that combination is the whole point of this tier.
Every image on this page is a real, unretouched GPT Image 1.5 generation with the exact prompt printed under it, on the same brand brief the whole catalog shares. Version-difference questions get answered by looking, not by reading changelogs.
What you can build with GPT Image 1.5
GPT Image 1.5 handles the same commercial briefs as the flagship: product scenes, promo graphics with readable text, mockups, and lifestyle frames. The finish is a step below GPT Image 2 on fine texture, and at 4 credits versus 7 that trade is exactly what iteration-heavy work wants.
The winning workflow is tiered: draft wide on 1.5, pick the direction, then re-run the winner on GPT Image 2 for the final. The prompts transfer verbatim because the family shares its prompt understanding.
Where GPT Image 1.5 earns its credits
Ad teams testing UGC-style creative variants use 1.5 as the volume layer: twenty variants cost 80 credits, and every generation shows its exact cost in your history. Content teams use it for blog and social imagery where the flagship's finish premium would never be noticed at feed size.
GPT Image 1.5 vs GPT Image 2, GPT Image 1, and Grok Imagine
The flagship finishes finer and holds typography more reliably at 7 credits. Draft on 1.5, finalize on 2; the same prompt works on both.
The legacy tier costs 5 credits, more than 1.5 at lower quality. Unless a workflow depends on its specific look, 1.5 supersedes it.
Grok is cheaper still at 3 credits and punchier, but less literal with instructions. 1.5 keeps the OpenAI family's prompt obedience.
