About Nano Banana 2
Nano Banana 2 is the next generation of Google's Nano Banana line, bringing noticeably more detail, better text rendering inside images, and resolution tiers up to 4K. On Avyn AI you choose the output size per generation — 1K for fast drafts, 2K for most production work, 4K when the asset needs to survive print or close inspection.
The step up from the original Nano Banana shows most in complex scenes: architecture keeps its lines straight, small faces in crowds stay coherent, and typography inside the image is far more likely to be legible. Prompt adherence is also tighter, so multi-part instructions land more reliably.
Because pricing scales with the resolution tier, a sensible workflow is to iterate at 1K and only pay for 4K on the final render. The same prompt carries across tiers, so nothing about your workflow changes except the output size.
Up to 4K resolution
Choose 1K, 2K, or 4K per generation. Draft cheap, finish sharp — the same prompt scales across tiers.
Enhanced detail and text
Cleaner fine detail, straighter geometry, and dramatically better in-image text than the previous generation.
Tighter prompt adherence
Multi-part instructions — subject plus setting plus style plus mood — land more reliably in a single generation.
What Nano Banana 2 is best at
High-resolution hero images for landing pages and campaigns.
Posters, banners, and assets with text baked into the image.
Detailed illustration and concept art that rewards close viewing.
Print-destined visuals that need 4K source files.
Upgrading a Nano Banana draft to a sharper final render.
Prompt tips for Nano Banana 2
Iterate at 1K, then re-run the winning prompt at 4K — the prompt carries across resolution tiers unchanged.
If the image includes text, put the exact wording in quotes and keep it short: “a poster that says ‘SUMMER SALE’”.
Describe fine details you care about (fabric texture, reflections, skin detail) — this model can actually resolve them.
