Nano Banana Pro costs $0.134 per image at 1K or 2K and $0.24 per image at 4K on Google's Gemini API, as of 31 October 2026, or half that ($0.067 and $0.12) with the Batch API. There is no free API tier. In the Gemini app, Google lists "Redo images with Nano Banana Pro" as a feature of its paid Google AI Plus, Pro and Ultra plans, so regular free use of Pro is limited at best.
That's the direct answer. Below is the full price picture: what Google charges per image, which Gemini plans include Pro, what "Nano Banana Pro free" really means in practice, and the cheaper alternatives if Pro is more than you need. Every Google figure comes from Google's own pricing, help and blog pages, linked at the end.
How much does Nano Banana Pro cost per image?
Nano Banana Pro's official model name is Gemini 3 Pro Image, and its API ID is gemini-3-pro-image. Here's Google's list price from the Gemini API pricing page (last updated 30 October 2026):
| Output size | Standard price per image | Batch API price per image |
|---|---|---|
| 1K | $0.134 | $0.067 |
| 2K | $0.134 | $0.067 |
| 4K | $0.24 | $0.12 |
| Free tier | Not available | Not available |
On top of the per-image price, input is billed per million tokens: Google lists $2.00 per million input tokens for text and images on the standard tier, and says one input image is roughly $0.0011. For a short prompt with one or two reference photos, that adds well under a cent.
What does that add up to?
- 100 images at 2K: $13.40 standard, $6.70 with Batch.
- 1,000 images at 2K: $134 standard, $67 with Batch.
- 1,000 images at 4K: $240 standard, $120 with Batch.
Two pricing quirks are worth knowing. 1K and 2K cost the same, so there's no reason to render Pro at 1K. And Batch halves the price for any job that can wait for results instead of returning in real time.
How does Nano Banana Pro's price compare with the other Nano Banana models?
Pro is the most expensive model in the family. Here are Google's standard per-image prices side by side, same source and date:
| Model | 1K | 2K | 4K |
|---|---|---|---|
Nano Banana Pro (gemini-3-pro-image) | $0.134 | $0.134 | $0.24 |
Nano Banana 2.1 (gemini-nano-banana-2.1) | $0.0336 | $0.0504 | $0.113 |
Nano Banana 2 (gemini-3.1-flash-image) | $0.067 | $0.101 | $0.151 |
Nano Banana 2 Lite (gemini-3.1-flash-lite-image) | $0.0336 | Not offered | Not offered |
Nano Banana (gemini-2.5-flash-image, deprecated) | $0.039 (up to 1024×1024) | Not offered | Not offered |
At 1K, Pro costs about four times as much as Nano Banana 2.1. At 4K the gap is about 2.1×. Whether that's worth paying depends on the image. Pro is Google's pick for dense text, infographics and complex, constraint-heavy prompts. For everyday images, Google's own docs recommend Nano Banana 2.1. We compare the two in detail in Nano Banana vs Nano Banana Pro.
Which Gemini plans include Nano Banana Pro?
In the Gemini app, Pro access depends on your Google AI plan. Google's Gemini Apps limits page, checked 31 October 2026, shows:
| Gemini plan | Nano Banana Pro in the Gemini app | Overall usage limits |
|---|---|---|
| No plan (free) | Not ticked for "Redo images with Nano Banana Pro" | "Standard limits" |
| Google AI Plus | Ticked | 2x standard limits |
| Google AI Pro | Ticked | 4x standard limits |
| Google AI Ultra | Ticked | 5x or 20x AI Pro limits, depending on subscription |
A few caveats from the same Google pages:
- No fixed image count. Google doesn't publish a daily number of Pro images for any plan, and says limits "may change without notice, including due to capacity constraints".
- Pro is a "redo" option. The help page lists Pro as "Redo images with Nano Banana Pro": you generate first, then re-render with Pro.
- Plan prices vary by country. Google's subscriptions page shows prices in local currency, so we haven't quoted one figure here. Check gemini.google/subscriptions for the price where you live.
- Watermarks differ by plan. When Pro launched on 20 November 2025, Google said free and Google AI Pro users keep a visible Gemini sparkle watermark, while it's removed for Google AI Ultra and for images made in Google AI Studio. All Google-generated images also carry an invisible SynthID watermark.
Can you use Nano Banana Pro for free?
Only in limited ways, and not through the API. Here is every route, with what Google actually states, as of 31 October 2026:
- Gemini app, free account. At launch (20 November 2025), Google said free users would get "limited quotas" of Pro, after which images fall back to the original Nano Banana. Google's current limits page doesn't tick Pro for users without a plan. In practice, expect little or no Pro on a free account.
- Google AI Studio. Google's pricing page says "Google AI Studio usage is free of charge in all available regions." It doesn't say how many Pro images that covers or whether a billing-linked project is needed, so check inside AI Studio.
- Gemini API. No free tier. The pricing page lists Pro's free tier as "Not available", so every API image is paid.
- Trials and third-party apps. Google mentions free-trial offers on its plans page without stating terms. Some third-party apps run time-limited Pro promotions. Read their terms; they're not Google's.
If you just want a Nano Banana model for free, the realistic option is Nano Banana 2 in the Gemini app: Google's limits page ticks it for users without a paid plan, at standard limits. We list every free route, with sources, on our Is Nano Banana free? page.
Can you use Nano Banana Pro on Kenerate?
No. As of 31 October 2026 Kenerate AI doesn't run Nano Banana Pro. It runs four other Nano Banana models in its image studio, and the closest to Pro is Nano Banana 2.1, Google's newest model:
| Model on Kenerate | Credits per image | Highlights |
|---|---|---|
| Nano Banana 2.1 | 21 at 1K · 31.5 at 2K · 42 at 4K (+4.2 with web search) | 1K–4K, 14 aspect ratios, up to 14 reference images |
| Nano Banana 2 | 14 at 1024×1024 (×2 at 2K, ×4 at 4K) | Web and image search |
| Nano Banana 2 Fast | 8 at 1024×1024 | Quick drafts |
| Nano Banana | 8 | The original, up to 10 references |
Credit packs start at $15 for 1,300 credits, which covers about 61 Nano Banana 2.1 images at 1K or 30 at 4K. Credits never expire and there's no subscription. Nano Banana models aren't on Kenerate's free plan: any credit pack unlocks them. New accounts get 25 free credits for the free-plan models (Qwen Image and Flux 2).
If your work is Pro territory (long text, dense infographics, client finals), use Pro through Google. For product shots, edits with several references, wide banners and short readable text, Nano Banana 2.1 is usually enough. You can check its real outputs and specs on the Nano Banana 2.1 model page.
Is Nano Banana Pro worth the price?
Pro earns its price when a failed render costs you more than the difference. In practice:
Pay for Pro when:
- the image is mostly text: posters, menus, packaging, slides, infographics;
- the prompt has many hard rules that must all land in one shot;
- the result is a client-facing final at 2K or 4K.
Use a cheaper model when:
- you're editing a photo (background, colour, lighting, removing objects);
- you're making social posts, thumbnails or drafts at 1K;
- you need hundreds of variants, where a 2–4× price gap adds up fast.
The money-saving workflow most teams use: draft on Nano Banana 2.1 or Nano Banana 2, then re-render only the winner on Pro. That's the same idea as the Gemini app's "Redo with Pro" button: you pay Pro prices for one image instead of twenty.
How do you keep Nano Banana Pro costs down?
- Render at 2K, not 1K. Same price on Google's API, more pixels.
- Use the Batch API for anything that doesn't need an instant result. It halves the per-image price.
- Draft on a Flash model first. Lock the composition on Nano Banana 2.1, then switch to Pro for the final.
- Start from prompts that already work. Our Nano Banana prompts library shows real outputs, so you spend less on trial and error.
- Keep reference images to what you need. Each input image adds token cost on the API.
- Watch your plan's limits. Google doesn't publish fixed Pro numbers for the Gemini app, so heavy users should track how often they hit the cap before paying for a higher plan.
The bottom line
As of 31 October 2026, Nano Banana Pro costs $0.134 per 1K or 2K image and $0.24 per 4K image on Google's Gemini API, or half that with Batch, with no free API tier. In the Gemini app it's a paid-plan feature: Google AI Plus, Pro and Ultra list "Redo images with Nano Banana Pro", and the free tier gets standard Nano Banana 2 instead. Kenerate doesn't run Pro, but its Nano Banana 2.1 covers most everyday Pro jobs with credits that never expire. For the background on every version, see what Nano Banana is. If you're calling Pro from code, our Nano Banana API guide covers keys and rate limits.
Updated 31 October 2026. Google prices and plan features come from Google's Gemini API pricing page, Gemini Apps Help and the Google blog on that date; Kenerate credit costs come from the app's model configuration and plan list. All of them can change.
