How do I get 4K images in Luren AI?
In the Image tab, choose a model that offers 4K, such as Google's Nano Banana Pro (for Pro members), Nano Banana 2 or Nano Banana 2.1, or ByteDance's Seedream 4.5 (all three open to everyone), select 4K in the resolution picker and generate. For an image you have already made, tap Upgrade to 4K on the result screen to get an enlarged, sharpened copy.
Generate in 4K
- Open the Image tab and type your prompt or add your photos.
- Pick a model that lists 4K, such as Nano Banana Pro, Nano Banana 2, Nano Banana 2.1 or Seedream 4.5.
- Tap 4K in the resolution picker. When the image is paid in coins, the picker shows the cost of each size.
- Generate, then tap Save to keep the full-size file on your phone.
- Nano Banana Pro costs more at 4K than at 2K, while Seedream 4.5 costs the same at both sizes.
- Some ready-made styles set the size themselves, so the resolution picker isn't shown.
Upgrade an image you already made
On the result screen, Upgrade to 4K runs your image through an enhancement step that enlarges it and sharpens detail while keeping the composition. The upgraded copy is made as a new creation and appears in History as a separate item, so the original stays as it was.
4K video
In the Video tab, Google's Veo 3.1 can render clips at up to 4K. Choose it, then set the resolution before you generate.
