Nano Banana 2 vs Nano Banana Pro
Both are Google image models, but they solve different jobs. Nano Banana 2 (Gemini 3.1 Flash Image) is the fast, cheaper default — roughly 2x faster and about half the cost per image. Nano Banana Pro (Gemini 3 Pro Image) is the specialist for 4K detail, character consistency, and text-heavy visuals. Below is a plain comparison, and you can run the same prompt through both free on this page.

At a glance: the key differences
The two models share a lineage but sit at different points on the speed/quality/price curve. These are the deltas that actually change your choice.
- Speed: Nano Banana 2 generates a 1K image in ~4–6s; Pro takes ~10–20s (and 4K is ~15–30s vs ~30–60s)
- Price: Nano Banana 2 is roughly half the cost per image at standard resolution
- Architecture: Nano Banana 2 is Flash-optimized (Gemini 3.1 Flash Image); Pro is built on Gemini 3 Pro Image
- Best at: NB2 = fast general generation and iteration; Pro = 4K detail, character consistency, and clean in-image text
When to use Nano Banana 2
For roughly 80% of everyday creative work, Nano Banana 2 is not just “good enough” — its speed and price make it the smarter default for iteration.
- Fast prompt iteration and concept exploration
- Social posts, avatars, and quick drafts
- High-volume batches where cost and speed matter
- A first pass before committing a winning prompt to Pro
When to use Nano Banana Pro
Pro is the specialist instrument. Reach for it when the final asset has to hold up at full resolution or carry legible text.
- Text-heavy visuals, posters, and infographics
- Premium 4K brand and product hero images
- Character consistency across a series of images
- Higher-stakes final assets where polish beats speed
常见问题
What is the main difference between Nano Banana 2 and Nano Banana Pro?
Nano Banana 2 is faster and cheaper — about 2x the speed and roughly half the price per image — built on Gemini 3.1 Flash Image. Nano Banana Pro, built on Gemini 3 Pro Image, produces higher-fidelity 4K detail and cleaner in-image text. Use NB2 for iteration and volume, Pro for premium final assets.
Is Nano Banana 2 better than Nano Banana Pro?
For most everyday work, Nano Banana 2 is the smarter default because it is faster and cheaper while producing high-quality output. Nano Banana Pro is “better” only for specific jobs: text-heavy layouts, 4K detail, and character consistency across a series.
Which is faster?
Nano Banana 2. It generates a 1K image in about 4–6 seconds versus roughly 10–20 seconds for Pro, and the gap widens at 4K (about 15–30s vs 30–60s).
Which is cheaper?
Nano Banana 2 costs roughly half as much per image as Nano Banana Pro at standard resolution, which is why it is the better pick for high-volume generation.
Can I try both for free?
Yes. Both Nano Banana 2 and Nano Banana Pro are available in the generator on this page. Run the same prompt through each, compare the output, and pick the one that fits your project — free daily credits included.
