Every model costs a fixed number of credits per image or per job, and every model draws from the same balance. Picking well is about matching the model to the job and not paying for more than you need.
Start with the tool's default
On a tool page the default model is already chosen for that job, and many tools narrow the model list to ones that suit it. Change it only when the result is not what you want. In the studio, the model list shows only models that support the mode you picked.
Photoshoots and headshots
For photoshoots, headshots and edits of your own photos, you want a model that keeps the face the same. Nano Banana is the default on most photo tools.
When the face drifts or you want sharper detail, Nano Banana Pro costs more per image and is often the fix.
Product shots
For product photos, the model has to keep the shape, label and text of the product. Seedream 4.5 is the default on the product photo tool. Always check labels before you publish.
Small, precise edits
For removing one object or changing one detail without touching the rest, FLUX Kontext is good at small, precise changes.
Cheap drafts from text
When you are exploring ideas in the studio without a photo, use a low-cost text to image model and move to a stronger one for the final version.
Compare before you spend
- The Generate and Full shoot buttons show the exact cost for your settings before anything is spent.
- Each model page shows its price, inputs and aspect ratios.
- The pricing page shows roughly how many results each plan buys on common models.
