Version 2.5 wins on fussy briefs
If your prompt has object counts, exclusions, or a lot of clauses, the newer model keeps more of them intact. That is the single clearest difference.
The previous OpenAI image model, kept available on purpose, with free signup credits to try it. Solid on photoreal product work and posters, and the pragmatic pick when you are running a lot of drafts.
Try GPT Image 2 free: new accounts start with 30 signup credits, no card needed. It is still cheap for bulk work, so compare it with GPT Image 2.5, then generate.
Same price table, different strengths. Open both pages and pick per job rather than per habit.
Both models cost the same number of credits here, so the choice is about behaviour, not budget.

If your prompt has object counts, exclusions, or a lot of clauses, the newer model keeps more of them intact. That is the single clearest difference.

Posters, packaging, and covers with real copy on them come back cleaner from 2.5. Version 2 is decent at this but loses letterforms more often.

A single product on a seamless background, a portrait, a texture study: on briefs this simple the two models are hard to tell apart.

If you have already tuned a prompt library against version 2, switching models means re-tuning it. Staying put is a legitimate reason to stay put.
