Use-case guide
Best AI image generator for ad creatives
Ad creatives live or die in the first second of a scroll, and every campaign needs the same idea in several sizes. You want a model that renders a clear offer, keeps the brand consistent and produces variations quickly enough to test.
Our picks
Pick 1
GPT Image 2.5
OpenAI
Places offer text, prices and calls to action where you ask, which makes it the strongest choice for ads that carry copy in the image.
- From 10 credits per image
- Up to 16 reference images
- 5 aspect ratios
Pick 2
Nano Banana 2
Google
Cheap enough to produce many variations for A/B tests, and keeps your product and brand assets consistent when you attach them as references.
- From 2 credits per image
- Up to 14 reference images
- 7 aspect ratios
Pick 3
Seedream 5.0 Pro
ByteDance
Covers the most aspect ratios, so one concept can be generated natively for feed, story and banner placements instead of cropped.
- From 7 credits per image
- Up to 1 reference image
- 8 aspect ratios

Tips for better results
- Lead with one message per creative: the product, the benefit, or the offer, not all three at full size.
- Generate each placement in its own aspect ratio (1:1 feed, 4:5 portrait feed, 9:16 stories) rather than cropping one image.
- Attach your logo and product photo as references and describe where the logo sits.
- Keep a winning prompt and change one variable at a time, such as the background colour or the headline, to learn what performs.
Questions
- Which AI is best for Facebook and Instagram ads?
- Use GPT Image 2.5 when the ad needs readable text, and Nano Banana 2 for fast, low-cost variations of a product shot. Generate 1:1, 4:5 and 9:16 versions for the main placements.
- Can I use AI-generated images in paid ads?
- Generally yes, provided you have the rights to any products, logos or people shown and the creative follows each ad platform policy. Review every image before it goes live.
- How many variations should I generate for a test?
- Three to five variations that differ in one clear way are usually enough to see a winner. Change one element at a time so the result tells you something.
