How to Access Nano Banana in Google AI Studio

If you’ve been hearing about Nano Banana and wondering how to actually get your hands on it — you’re in the right place.

Google’s Nano Banana is the image generation model built into Gemini. It lets you create, edit, and iterate on visuals using nothing but plain language. No design skills required. No complex software. Just a prompt and a Google account.

And the fastest way to access it? Google AI Studio — a free developer playground where you can start generating images in under two minutes.

This guide walks you through exactly how to do that, what each version of Nano Banana offers, and how to get the most out of every generation.

What Is Nano Banana?

Nano Banana is Google DeepMind’s AI image generation and editing technology, built natively into the Gemini model family. It’s not a standalone app — it’s the image engine powering Gemini’s visual capabilities across Google’s ecosystem.

There are three versions currently available:

• Nano Banana — Powered by Gemini 2.5 Flash Image. Built for speed and efficiency, optimized for high-volume and low-latency tasks. Free to use in AI Studio.
• Nano Banana Pro — Powered by Gemini 3 Pro Image (launched November 20, 2025). Studio-quality results with advanced text rendering, up to 14 reference images, and resolutions up to 4K.
• Nano Banana 2 — Powered by Gemini 3.1 Flash Image (latest release, March 2026). Combines the speed of Flash with the advanced intelligence of Pro. Subject consistency for up to 5 characters and 14 objects in a single workflow.

Each version outputs images embedded with SynthID, Google’s invisible watermarking technology that marks AI-generated content without affecting visual quality.

Why Google AI Studio Is the Best Starting Point

Google AI Studio (aistudio.google.com) is the official developer playground for all Gemini models — including Nano Banana. Here’s why it’s the best place to start:

• It’s free. You can use the standard Nano Banana model at no cost with your Google account. Free tier users also get 500 image generation requests per day using Gemini 2.5 Flash Image.
• No downloads. Everything runs in your browser.
• Full control. Adjust aspect ratio, resolution, temperature, and model version directly in the interface.
• API access. Once you’re ready to integrate into a product or workflow, you’re already in the right environment to grab your API key.

How to Access Nano Banana in Google AI Studio — Step by Step

Step 1: Go to Google AI Studio

Open your browser and navigate to aistudio.google.com.

This is Google’s official developer portal for Gemini models. You don’t need to install anything.

Step 2: Sign In With Your Google Account

Click Sign In and log in with any Google account — personal or work. If you don’t have one, creating an account is free and takes about two minutes.

Once signed in, you’ll land on the AI Studio home dashboard.

Step 3: Select the Nano Banana Model

On the homepage, you’ll see a clear entry for Nano Banana. Depending on when you access it, you may see it labeled as:

• Nano Banana (Gemini 2.5 Flash Image) — free, high-speed
• Nano Banana Pro (Gemini 3 Pro Image) — marked “New,” premium
• Nano Banana 2 (Gemini 3.1 Flash Image Preview) — latest release

Click on the Nano Banana model to open the generation interface.

Pro tip: For direct access to the standard model, use the AI Studio model picker and search for “image” to filter to image-capable models immediately.

Step 4: Create a New Project

Once inside the model playground:

1. Click “Create new” or “New project” in the interface.
2. Select “Image Generation” as your task type.
3. You’ll see a blank canvas ready for your first prompt.

Step 5: Write Your First Prompt and Generate

Type your prompt directly into the input field. A strong starting formula:

Create/generate an image of [subject] [action] [scene/context]

For example: “Create an image of a minimalist ceramic coffee mug on a polished concrete surface, studio lighting, matte black finish.”

Hit Generate and Nano Banana processes your request. Standard generations take under 5 seconds on the free tier.

Step 6: Edit and Refine

Once your image appears, you can continue the conversation to make edits:

• “Change the background to a warm wooden table.”
• “Make the lighting warmer and add soft shadows.”
• “Replace the mug with a glass water bottle.”

Nano Banana’s edit consistency keeps your original image stable while applying only the changes you describe. This is where it outperforms most image tools — precise, instruction-following edits without starting from scratch.

Step 7: Export Your Image

When satisfied, click Download to save your image. Supported formats are PNG and JPEG. Free tier images include the standard SynthID watermark (invisible in most use cases). AI Studio developer outputs do not carry a visible Gemini sparkle watermark.

Understanding the Free vs. Paid Access Tiers

Here’s how access breaks down across user types:

For most use cases — prototyping, creative experimentation, marketing mockups — the free AI Studio tier is more than enough to get started.

Accessing Nano Banana Pro in AI Studio

Nano Banana Pro (Gemini 3 Pro Image) is available in AI Studio in preview. Here’s how to access it specifically:

1. Log in to aistudio.google.com
2. In the left sidebar, click Playground
3. In the model selector, look for “Nano Banana Pro” — it may be labeled “Gemini 3 Pro Image”
4. You’ll see the model tagged as “New” with the description: “State-of-the-art image generation and editing model”
5. On the right panel, configure your settings: resolution (Auto / 1K / 2K / 4K), aspect ratio, and temperature
6. If you haven’t set up billing, click “Link API Key” to connect your Google Cloud project

Important: AI Studio includes free monthly credits for experimentation with Nano Banana Pro. The Gemini 3 Pro Image API does not have a permanent free tier — standard Nano Banana (Gemini 2.5 Flash Image) remains free with 500 daily API requests.

Setting Up API Access for Nano Banana

If you want to use Nano Banana programmatically — inside an app, workflow, or automated pipeline — here’s how to get your API key:

1. In AI Studio, click “Get API key” in the left navigation panel
2. Click “Create API key”
3. Select an existing Google Cloud project or create a new one
4. Copy your API key and store it securely

Pricing (as of early 2026):

• Image generation costs approximately $0.039 per image
• That’s roughly 25 images for $1
• Official rate: $0.30 per 1M input tokens / $30 per 1M output tokens

For prototyping and development, AI Studio is free. For production deployment via API, billing must be enabled on your Google Cloud project.

What Makes Nano Banana 2 Different

Released in March 2026, Nano Banana 2 (Gemini 3.1 Flash Image) represents the current benchmark for accessible AI image generation. Key upgrades over the original:

• Subject consistency — Maintain character resemblance for up to 5 people and 14 objects across a single workflow. This means you can create storyboards or brand narratives without characters changing appearance between frames.
• Precise instruction following — The model adheres more strictly to complex, nuanced prompts. What you ask for is what you get.
• Production-ready specs — Full control over aspect ratios and resolutions from 512px all the way to 4K. Vertical social posts, widescreen backdrops, print assets — all covered.
• Visual fidelity upgrade — Vibrant lighting, richer textures, and sharper detail at Flash speeds.
• Advanced world knowledge — Pulls from Gemini’s real-world knowledge base and real-time web search to accurately render specific subjects.

Nano Banana 2 is now the default image generation model in Flow (Google’s AI filmmaking tool), available to all Flow users at zero credits.

Where Else Can You Access Nano Banana?

While AI Studio is the best starting point, Nano Banana is available across Google’s full product ecosystem:

• Gemini App (web and mobile) — Select “🍌 Create images” from the tools menu. Use Fast, Thinking, or Pro model from the model picker.
• Google Search (AI Mode) — In AI Mode, select “Thinking with 3 Pro,” click the plus icon, and choose “Create Images Pro.” Available in select countries in English.
• NotebookLM — Available globally to all users for turning sources into visual Slide Decks and Infographics.
• Google Slides and Vids — Available to Workspace customers.
• Google Ads — Powers AI creative suggestions for campaigns.
• Google Flow — Default image model for AI filmmaking workflows.
• Vertex AI — Enterprise access with scaled generation capabilities.

Tips for Getting Better Results With Nano Banana

Getting the most out of any AI image model comes down to how you prompt it. Here’s what consistently produces better outputs:

Be specific about style and context. Instead of “a coffee shop,” try “a busy independent coffee shop in Berlin, morning light, analog film grain, 35mm.”

Reference real-world knowledge. Nano Banana is built on Gemini’s world knowledge. Prompts that reference real places, aesthetics, or styles tend to produce more accurate results.

Use follow-up edits rather than starting over. The model’s edit consistency is one of its strongest features. Build your image iteratively rather than trying to get everything in one prompt.

Specify resolution and aspect ratio. If you need a vertical social post, say so. If you need a 4K widescreen, specify it. The model can handle 512px to 4K, but it defaults to standard unless told otherwise.

Upload reference images for brand consistency. Nano Banana Pro and Nano Banana 2 accept up to 14 reference images. Feed it your brand colors, product shots, or character references to maintain visual consistency across assets.
