# Google AI Studio Usage Guide: 3 Ways to Access Gemini Models Easily

> Google AI Studio is Google's free AI development platform, but using paid models like Nano Banana Pro requires an overseas credit card. This guide explains three solutions: API relay service (80% discount), membership proxy (¥230/month), and official subscription.

## Key Highlights

## Why Does Nano Banana Pro Require API Key Binding?

### What is Nano Banana Pro?

**Nano Banana Pro** is Google's latest image generation model released in November 2025, also known as **Gemini 3 Pro Image**. It can generate high-quality images at 1080p, 2K, and even 4K resolutions, making it Google's most powerful image generation model to date.

### Why is API Key Required?

Unlike text models like Gemini 2.5 Flash, **Nano Banana Pro has no free quota**. This means:

<Warning>
  **Billing Requirements**

  * Must create a Google Cloud project and enable billing
  * Must bind a valid credit card (typically requires overseas credit card)
  * Google will verify credit card validity and cardholder identity
  * Pricing: \$0.139/image (1080p/2K), \$0.24/image (4K)
</Warning>

### What are the Barriers?

Many users face the following challenges when trying to use Nano Banana Pro:

1. **Overseas Credit Card Requirement**: Google Cloud typically requires overseas credit cards (Visa, MasterCard, etc.)
2. **Strict Verification**: Google verifies cardholder identity; some cards may fail verification
3. **Complex Process**: Requires registering Google Cloud, creating projects, setting up billing accounts, etc.
4. **Exchange Rate Loss**: Foreign currency payments may incur exchange rate losses and processing fees

<Info>
  **Key Information**

  The API Key bound in Google AI Studio is actually a **Google Cloud** API Key, not a simple AI Studio Key. This means you need Google Cloud billing permissions, which is the main reason for the high barrier.
</Info>

## Three Solution Comparison

To address these barriers, we offer three solutions with different pros and cons. Choose based on your needs.

### Solution 1: API Relay Service (APIYi)

  **Code Example**

  ```python theme={null}
  import openai

  client = openai.OpenAI(
      api_key="your-apiyi-api-key",
      base_url="https://api.apiyi.com/v1"
  )

  # Call Nano Banana Pro (Gemini 3 Pro Image)
  response = client.images.generate(
      model="nano-banana-pro",

APIYi achieves lower costs through bulk purchasing and optimized technical architecture. As a relay platform, it eliminates the complex process of users directly interfacing with Google Cloud, reducing operational costs.

### Q2: Is membership proxy safe?

Choosing reputable proxy services is relatively safe, but note:

* Select platforms with good reputation
* Don't use main account, recommend separate Google account
* Regularly change passwords, enable two-factor authentication

### Q3: What's the difference between free Google AI Studio and paid membership?

| Item                         | Free          | AI Pro   | AI Ultra |
| ---------------------------- | ------------- | -------- | -------- |
| Gemini 2.5 Pro conversations | 5/day         | 100/day  | 500/day  |
| Image generation             | 100/day       | 1000/day | 1000/day |
| Veo video generation         | Not supported | 3/day    | 5/day    |
| Deep Research                | 5/month       | 20/day   | 200/day  |
| Cloud storage                | 15GB          | 2TB      | 30TB     |

### Q4: How to choose the right solution?

* **Low-frequency use**: Free Google AI Studio (less than 5 conversations daily)
* **API integration**: APIYi relay (low price, high concurrency)
* **Daily creation**: Membership proxy (full experience, reasonable price)
* **Enterprise applications**: Official subscription (highest guarantee)
