Guida ai prompt GPT Image 2: struttura, esempi e controllo dello stile

GPT Image 2 è un modello di immagini ad alto controllo su OmniArt per brief che combinano composizione, testo visibile, reference e requisiti di dettaglio precisi. Non garantisce testo corretto in una sola generazione, quindi il risultato va sempre verificato.

Questa guida offre una struttura riutilizzabile in sei parti e 12 prompt pronti da copiare. Sono punti di partenza selezionati, non un benchmark controllato; i prompt restano in inglese in tutte le traduzioni per essere incollati direttamente.

GPT Image 2 su OmniArt

Supporta 1K, 2K, 4K, detail Low/Medium/High, nove immagini e seed ripetibile. Il modello è per tutti; detail alto e 2K+ richiedono Starter. I crediti dipendono da risoluzione e detail, quindi valida il layout in 1K Low.

Struttura del prompt in sei parti

Usa “output e stile + soggetto + ambiente + luce e materiale + composizione e gerarchia + vincoli esatti”. Scrivi il testo visibile, assegna un ruolo a ogni immagine e, con seed fisso, correggi un problema alla volta.

Sei abitudini utili

1. Parti dall’output. 2. Spiega relazioni con frasi. 3. Metti la copia esatta tra virgolette. 4. Un ruolo per riferimento. 5. Blocca il seed per piccole modifiche. 6. Correggi un errore alla volta.

Prompt library: 12 brief pronti

I punti 1–12 coprono packshot, colore, poster bilingue, turnaround, stanza, cibo, moda, infografica, app store, thumbnail, storyboard e identità. Per incollarli direttamente, i prompt restano in inglese in tutte le lingue.

Controllo dello stile: cosa funziona, cosa no

GPT Image 2 accetta direzione stile in linguaggio naturale meglio dello spam di keyword. Tre pattern che instradano in modo affidabile:

Due pattern che non funzionano:

• Accumulare molti aggettivi di stile («dreamy ethereal cinematic photoreal hyperrealistic»). Il modello li media in melma.
• Chiedere un logo brand esatto. La riproduzione logo è inaffidabile; componi il logo in post.

Usare immagini di riferimento

Nove immagini aiutano solo con ruoli chiari. image 1 può controllare geometria, image 2 composizione, image 3 materiale o colore. In modifica, elenca prima ciò che deve restare e poi descrivi il cambiamento.

Limiti onesti

Il testo visibile va controllato; loghi esatti e copia regolamentata vanno composti dopo. Più viste possono deviare in identità, accessori o geometria. Risoluzione e detail non correggono un brief ambiguo, seed non garantisce pixel identici.
