Social Media Ad — Side-by-Side Results
Prompt
"A late-20s woman with shoulder-length wavy brown hair in a cream sweatshirt and light-wash jeans holds a pastel bottled iced coffee (label facing camera) while seated at a sunny neighborhood café window, glancing toward the phone camera mid-laugh like she just started recording an Instagram story. One hand rests on a laptop and tote bag on the table, with a half-eaten croissant nearby for a casual “work break” vibe; bright natural window light, slight handheld phone perspective, clean aspirational product placement like a TikTok UGC ad."

Verdict
Choose GPT-Image 1.5 when your social ad needs a premium, highly controlled “final” look—especially for product hero shots, complex lifestyle scenes, or creatives where small details and realism matter. Its quality tiers also make it easy to start with quick drafts and scale up when you’re ready to export a flagship asset.

It’s a strong fit for always-on paid social where iteration cadence matters as much as visual polish.
