Same family, three different jobs
Nano Banana 2 is not one model; it is a family of tiers that trade per-image cost against output ceiling. Lite is the cost-optimized tier built for volume, the standard 2 is the balanced general-purpose tier, and Pro is the flagship for maximum detail. Choosing between them is an economics question before it is a quality question: what does one more unit of resolution buy you at the placement you are actually shipping to?
On Nano Banana we run the Lite tier in production, so we can speak about it with real numbers. For the standard 2 and Pro tiers we summarize public information as of July 2026 — treat those columns as reference, and verify current specs before you commit budget.
What we run: Nano Banana 2 Lite, in facts
Our production configuration is gemini-3.1-flash-lite-image serving 1K PNG output in 10 aspect ratios, at a reference base price of about $0.0336 per image (input and other tokens can add cost). Every output carries an imperceptible SynthID watermark.
That profile makes Lite the direction-comparison tier: at roughly three cents base per image, exploring a wrong direction costs almost nothing, which is why our whole workbench is built around batches of up to 80 variants on a fixed contact sheet.
- Billing on Nano Banana: 1 credit per succeeded 1K image — failed or blocked slots release their reserve.
- Best for: listing variants, ad creative testing, marketplace crops, batch proofing.
- Not for: print resolution or hero placements that demand maximum detail.
Where the standard 2 and Pro fit
Per public materials, the standard Nano Banana 2 tier raises the resolution ceiling above Lite at a higher per-image price — the right tool when one hero image matters more than twenty comparisons. Pro sits at the top of the family: highest detail, highest price, aimed at final production assets.
We deliberately do not quote speed or exact specs for those tiers — we do not run them, and public numbers change. The honest comparison is about workflow shape, not benchmark scores.
A decision rule you can apply in one minute
Ask what your bottleneck is. If you are deciding between directions — backgrounds, angles, hooks, crops — Lite wins on unit economics: proof twenty directions at 1K, pick two winners, then re-render only the winners at a higher tier if the placement demands it. If you already know the direction and need one definitive asset, start at the tier whose resolution matches the placement and skip the comparison phase entirely.
- Bottleneck = choosing → Lite, in batches, at 1K.
- Bottleneck = one hero image → standard 2 or Pro, single render.
- Unsure → start at Lite; a wrong 1K proof costs cents, a wrong 4K render costs real budget.
The bottom line
There is no universally better tier — there is a better tier per job. Our comparison page keeps the Lite column from our real production data and labels everything else as public-info reference, so you can check the numbers yourself before spending anything.
