Nano Banana Pro for photoreal and references

Nano Banana Pro is the default for a reason. It is the most photoreal of the three, it renders faces and small text cleanly, and it accepts up to four reference images. That last part matters more than any prompt trick: give it your actual product photo and ask for a new scene, and the label, colour and shape stay yours. It renders at 1K, 2K or 4K, and in ten aspect ratios from 21:9 banners to 9:16 stories.

GPT Image 2 for layout and copy

GPT Image 2 is the most literal. When an image is mostly typography — a poster, a menu, an infographic-style ad with a headline, a subline and a button — it follows the layout you describe closely. It also takes up to four reference images, and its Low, Medium and High quality settings let you draft cheaply and spend only on the final.

Grok Imagine for bold styles

Grok Imagine is the stylist. It does not take references, but for illustration, saturated colour and unusual shapes — including very wide and very tall formats — it is fast and inexpensive in credits.

Writing image prompts that work

Structure beats length. Say what the image is for (“vertical social ad”, “YouTube thumbnail”), the subject and what it is doing, the setting, the light, and any exact text in quotes. If the image needs a brand, describe the shape and colour of the logo or attach it as a reference instead of hoping the model guesses. For products, attach the photo and say “keep the product, logo and lettering unchanged” — it is the line that stops a model from redesigning your packaging.

Images are also the cheapest way to get a video right. Generate the first frame here, then open the image-to-video flow and describe only the motion.
