Pick by task
Which should you choose?
Most people end up using both — here's the split.
Posters & thumbnails with text
Readable headlines and labels are GPT Image 2.5's signature strength. If the image must contain words, start here.
Multi-image references
Combining several reference images — product plus background, character plus scene — is where Nano Banana 2's workflow shines.
Precise photo edits
Change one thing and keep everything else: background swaps, object removal, restyles that follow instructions. See our photo editing guide.
Photorealistic lifestyle shots
Natural light, lifelike skin tones, scenes that don't look staged — strong picks for lifestyle blogs and product contexts.
Complex composed scenes
Multi-element layouts where everything must sit in the right place — GPT Image 2.5 follows spatial instructions more literally.
