Nano Banana Pro Guide: Premium AI Images With Sharp Text

Nano Banana Pro is Google's premium image model, the one to use when a picture needs the best detail and the cleanest text. In Wellshot it makes images from text or edits them with up to 14 reference pictures, at 1K, 2K or 4K. This guide covers when the premium model is worth it, how to prompt it for product and title work, and how it compares with Nano Banana 2.1 and Seedream.

Nano Banana Pro at a glance

Nano Banana Pro comes from Google (Google DeepMind). It sits above Nano Banana 2.1 as the premium option.

Next to Nano Banana 2.1 the specs look the same on paper: same sizes, same 14-reference limit, same ratios. The difference is the level: Pro is the premium model for detail and text, and 2.1 is noted for strong edits, text and character consistency.

When the premium model is worth it

Every image in Wellshot costs credits, with the price shown on the button before you run, so you can compare Pro with a lighter model on the same shot before committing. Use Pro where the extra quality will be seen:

• Hero images. The one still that opens the campaign or sits on the product page.
• Small text that must be sharp. Labels, ingredient lists, dials, fine print on packaging.
• Titles and posters. Big type that has to be spelled right and look designed.
• Tight close-ups. Textures, materials and small product details.

For everything before that point (options, layouts, boards), a cheaper model is fine. A common routine: draft with Seedream 5.0 Flash, refine with Nano Banana 2.1, then make the final with Nano Banana Pro.

Prompting for detail and text

A few habits get more out of Pro:

1. Quote every word you want on the picture. "A label that reads "NO. 7 / 50 ML"" leaves no room for guessing.
2. Say where the text goes. Top, bottom, on the bottle, on the sign.
3. Say what not to add. "No other text" stops extra lines appearing.
4. Describe the material. Brushed steel, frosted glass, matte paper: the model has more to render.
5. Name references by role. @Image 1 is the product to keep exactly, @Image 2 is the set, and so on.

A worked example: a watch hero shot

You have a picture of the watch (@Image 1), a slate surface (@Image 2) and a mood picture with water droplets (@Image 3).

Luxury product photograph, 4:5, 4K. The watch from @Image 1 lies on the dark
slate surface from @Image 2, dial facing camera, slightly angled. Fine water
droplets on the glass and strap like @Image 3. One soft key light from top left,
a thin specular highlight along the bezel, deep shadows. Keep the dial, hands,
case and strap exactly as in @Image 1. On the slate below the watch, small
engraved text that reads "TIDE / 300 M". No other text, no logos added.

This plays to Pro's strengths: fine detail in the droplets and bezel, small text that has to be crisp, and a 4:5 ratio that only the Google models offer in Wellshot.

From hero still to product video

An approved Pro still makes a strong start frame. In Wellshot:

1. Generate the hero still with Nano Banana Pro.
2. In the Studio, switch to video mode and set the still as the start frame. On the Canvas, wire the image node into a video node's first frame input.
3. Pick a video model and describe the move (a slow orbit, a splash, a push in).
4. To save credits on motion tests, use Seedance draft mode: a cheap 480p preview first, then render the one you like at full quality from the same draft.

Using Pro inside a team

On Crew and Production plans, a team shares projects and one credit pool. A sensible rule for agencies is to keep Pro for the frames going to the client, and let the rest of the team explore with cheaper models. Because every take is saved on the shot, the Pro final sits right next to the drafts that led to it. More in our post on AI video tools for teams.
