GPT Image 2 and 1.5 Generation

GPT Image spans three generations of OpenAI image models, each pairing text-to-image with an edit mode for adding, removing or changing parts of a picture.

* ABOUT GPT IMAGE

Working with GPT Image

This family covers OpenAI's image models across three generations. GPT Image 2 leads on prompt understanding, compositional consistency, physically accurate lighting and fine detail; 1.5 delivers accurate prompt interpretation with consistent composition; and the original GPT-1 image pair covers straightforward generation and area-based editing.

When to choose GPT Image

Choose GPT Image when prompt fidelity and lighting realism matter and you are already working in the OpenAI ecosystem. Nano Banana and Flux are the alternatives with wider price ladders.

Choosing between the variants

GPT Image v2 is the current generation and the default choice. v1.5 remains a cheaper capable option, and the GPT-1 pair is the simplest — generation plus an edit that fills a selected area naturally.

About GPT Image

What improves in GPT Image 2?
Higher fidelity, stronger prompt understanding, better compositional consistency, more physically accurate lighting and finer detail rendering.
How does the edit mode work?
You mark the area to change and the model fills it naturally, so parts of an image can be removed, added or altered without regenerating the frame.
Which generation should I start with?
v2 unless cost is the constraint, in which case v1.5 gives most of the prompt accuracy for less.
