Nano Banana 2
Gemini image with explicit 1K, 2K, and 4K resolution tiers. Same reference and aspect-ratio surface as the rest of the family. Pay for the size you ship.
Nano Banana 2 is the resolution-tiered Gemini image model in the Nano Banana family. One resolution parameter picks 1K, 2K, or 4K and maps to three rate-card lines, so you know exactly what each output costs based on the size you asked for. Aspect ratios and reference handling are the same as Nano Banana Pro, but Nano Banana 2 skips the reasoning step — it is faster per call and cheaper per image.
If you need photoreal output or working text rendering, Nano Banana Pro is the right call. Nano Banana 2 is for production work where 4K matters but reasoning does not.
What it is good at
Campaign packs across resolutions
Locks the look across web, mobile, and print.
Ecommerce catalog grids
Reference-guided product stills at the resolution each surface needs. PDP at 4K, listing thumbnails at 1K.
Pitch deck hero art
4K output covers projector and conference-room display sizes without an upscale step.
Multi-channel social
Generate the master at 4K, downscale for each social spec.
Quality-vs-cost A/B testing
Same prompt at 1K and 4K shows whether the resolution upgrade actually matters for your use case.
High-volume iteration
No reasoning step means lower latency per call. Useful when a creative team is sweeping dozens of prompt variants before locking a direction.
When to pick Nano Banana 2 over Pro
Head to head
Compared to Nano Banana Pro
- Faster per call. Pro runs a reasoning pass before drawing, which adds latency on every request.
- Cheaper per image at every tier. Nano Banana 2 is priced at 1K, 2K, and 4K rate-card lines below Pro 1K/2K.
- Same ten aspect ratios and the same 20-image, 10 MB reference-image surface. The migration in either direction is a model-name change.
- Right pick when you do not need legible in-image text or photoreal materials — for example concept exploration, listing thumbnails, or social packs that get downscaled anyway.
- Reach for Pro when text inside the image must be readable, when product shots need to ship without retouching, or when the prompt has six or more subjects that have to hold their composition.

Pro swaps to Gemini 3 Pro Image with a reasoning pass, photoreal output, and working text rendering. Pick Nano Banana 2 when you do not need legible text or photoreal materials and you want predictable cost at 1K, 2K, or 4K. Pick Pro when the asset has to ship without retouching.
Use Nano Banana 2 for ecommerce catalog runs, multi-channel social packs, fast iteration, and any job where you are A/B testing prompts and resolutions. Use Pro for marketing posters with body copy, photoreal product hero shots, and complex multi-subject scenes.
