Frequently asked questions

Which AI image generator is the best?

It depends on the job. Nano Banana Pro is strong at precise edits and compositions, GPT Image 2 at following the prompt closely and at text inside images, Seedream 5.0 at stylized visuals, and Nano Banana 2 Lite and Seedream 5.0 Flash at fast drafts. In Sky Studio you can run the same prompt on several of them and keep the best result.

Can I use my own reference images?

Yes. Every image model accepts reference images, so you can keep a product, a character or a style consistent across new images.

What resolution can I generate?

Up to 4K with Nano Banana 2, Nano Banana Pro and GPT Image 2; Seedream 5.0 renders at 2K and Nano Banana 2 Lite at 1K.

Do I need a subscription?

No. Sky Studio is pay as you go: you buy credits when you need them, and they never expire. The app shows the cost of each image before you generate.

Can I use the images commercially?

Sky Studio is built for commercial work, but you are responsible for your prompts and source material. Avoid brands, characters and copyrighted references you do not have the rights to use.
