Nano Banana Pro isn’t entirely free — its cost depends on your usage tier and platform.
Free users can try the model in the Gemini app for three low-resolution generations, while full 2K and 4K outputs require a paid plan or API-based billing. Developers using Google AI Studio pay per image — about $0.15 per 4K generation.
Here’s a complete breakdown of the plans, pricing, and free-trial options as of 2025.
The Google official Nano Banana Pro service is currently very congested — especially for free users, who are limited to only three generations at lower resolution. The good news is that GlobalGPT has fully integrated Nano Banana Pro, allowing you to use it here freely and without restrictions.

What Is Nano Banana Pro and Why It Costs More
Nano Banana Pro (also called Nano Banana 2) is powered by Gemini 3 Pro Image, Google DeepMind’s flagship AI for image generation and editing.
It produces studio-quality visuals with advanced reasoning, text rendering, and factual grounding.
Compared to Nano Banana (Gemini 2.5 Flash Image), the Pro version offers:
- 2K and 4K resolution output
- More realistic textures and lighting accuracy
- Multilingual and localizable text inside images
- Connection to Google Search for real-time knowledge
- Up to 14 image inputs and 5 consistent characters
Because of its high computational load, Nano Banana Pro operates under a paid usage structure, with limited free trials for casual users.

Nano Banana Pro Pricing by User Tier
| User Type | Access Platform | Resolution Support | Quota / Billing | Cost (Approx.) |
|---|---|---|---|---|
| Free Users | Gemini App / LMArena | 1 MP (≈1024×1024) | 3 generations only | Gratuit |
| Pro Subscribers | Gemini App + AI Mode (US only) | Up to 4K | High quota limit | Subscription fee |
| Ultra Subscribers | Gemini App / Flow | 4K max, full controls | Highest priority & speed | Subscription fee |
| Developers / Enterprise | Google AI Studio / Vertex AI | Up to 4K | Pay-per-generation | ≈$0.15 per 4K image |
| GlobalGPT Integration | GlobalGPT Platform | Up to 4K | Unlimited usage | as low as $5.3/month |
Google’s official pricing applies to Gemini and AI Studio platforms; integrated platforms like GlobalGPT offer more flexible or free access for testing and creative use.
Understanding Google’s Pricing Model
Nano Banana Pro’s cost is based on compute resources et output quality.
Higher resolution and more complex prompts consume more GPU power, which is why Google ranks the model under premium tiers.
Price Factors:
- Output size: 1 MP (Free) → 4K (Pro) → 4K (Ultra)
- Prompt complexity: Multilingual and factual content uses more tokens
- Consistency features: Maintaining faces and textures requires larger processing
- Studio integration: Developers using API or Vertex AI pay per request
For developers, each API key must have billing enabled in AI Studio. Without it, Nano Banana Pro defaults to the basic Gemini 2.5 model.
