Core Value: By the end of this post, you'll understand exactly where AI Studio and Gemini sit in the ecosystem, the availability of Nano Banana Pro across different platforms, and the best usage plan for your workflow.

Google AI Studio vs. Gemini: The Core Differences

In a nutshell: Gemini is the AI engine, while AI Studio is the developer's workshop. Their positioning and target audiences are entirely distinct.

What is Gemini?

Gemini is Google's family of Large Language Models, including various versions like Gemini 3 Pro and Gemini 2.5 Flash. At the same time, Gemini is also a consumer-facing AI assistant app (gemini.google.com), much like ChatGPT.

Key features of the Gemini app:

• Accessible directly via browser or smartphone.
• Integrates with Google services like Gmail, Docs, and Calendar.
• Features "Gems" (custom AI experts).
• Pro members can use Nano Banana Pro for image generation.

What is Google AI Studio?

Google AI Studio is an experimental platform for developers. It allows you to test and debug Gemini models and obtain API Keys for your own applications.

Key features of AI Studio:

• Offers free testing for base models.
• Allows fine-tuning of parameters like Temperature and Top-P.
• Provides API Keys for integration into your own projects.
• Cannot directly use Nano Banana Pro to generate images (this requires the paid API tier).

Nano Banana Pro Availability Across Platforms

Nano Banana Pro (gemini-3-pro-image-preview) is Google's latest high-quality image generation model, but how you use it varies significantly across different platforms:

Gemini App: The Easiest Way to Experience It

If you just want to experience Nano Banana Pro's image generation capabilities, the simplest way is:

1. Visit gemini.google.com
2. Subscribe to Google AI Pro ($19.99/mo)
3. Describe the image you want directly in the chat box
4. Download the generated image directly

Pros: Simple to use, supports direct image downloads.
Cons: Requires a US-based account and credit card; doesn't support batch processing.

AI Studio: A Developer Testing Environment

While you can chat in AI Studio, it's specifically designed for developer testing and API debugging:

• You can test text models like Gemini 2.5 Pro and Flash for free.
• Nano Banana Pro requires a paid tier to use.
• Even if it's accessible, it's meant for testing and isn't ideal for production environments.
• You'll need to link a credit card to enable Cloud Billing.

Why You Might Have Trouble Using Nano Banana Pro in AI Studio

Many developers are confused: AI Studio clearly lists the gemini-3-pro-image-preview model, so why isn't it working?

Reason 1: Preview Model Restrictions

Nano Banana Pro is currently in Generative AI Preview status:

• Preview models have much stricter rate limits.
• Free tier RPD (Requests Per Day) can be as low as 50-100.
• You'll frequently encounter 503 errors (model overloaded).

Reason 2: Paid Tier Required

To use the Nano Banana Pro API in AI Studio, you need to:

• Enable Cloud Billing (link a credit card).
• Upgrade to Tier 1 or higher.
• Even with a paid account, the RPD is capped at 250 requests per day.

Reason 3: Technical Barriers

Image editing features require handling a thoughtSignature:

• Every conversation step needs to pass signature information.
• Missing signatures will result in 400 errors.
• This requires a certain level of technical expertise from the developer.

3 Ways to Use Nano Banana Pro

Based on your needs, here are three recommended options:

Option 1: Subscribe to Gemini Pro

Best For: Individual users, light usage, or those wanting to try the latest features.

• Top-up: ai.daishengji.com (Recommended for Alipay support)

Option 2: Use AI Studio API

Best For: Developers who need to integrate AI into their own applications.

import google.generativeai as genai

genai.configure(api_key="YOUR_API_KEY")

model = genai.GenerativeModel('gemini-3-pro-image-preview')
response = model.generate_content("Generate a cyberpunk style city night scene")

Issues:

• Requires binding an international credit card.
• Mainland China is not a supported region.
• Strict RPD (Requests Per Day) limits (Tier 1 is only 250/day).
