Google AI Studio Free Access: What's Still Free and What Isn't

Yes, you can use Google AI Studio without paying. Google's pricing page says AI Studio usage is "free of charge in all available regions," and you can sign in at aistudio.google.com and start prompting without a subscription or a credit card.

That yes comes with three conditions. Your account has to be eligible in the first place. The free quota is modest, and Google doesn't publish a number for it. And since April 20, 2026, premium models such as Gemini Pro and Nano Banana sit behind a Google AI Pro or Ultra subscription in the web app, or behind a paid API key.

What you pay depends on which of three separate things you're using: the AI Studio website on its Free plan, the same website with a Google AI subscription, or a Gemini API key. Each has its own rules, and mixing them up is how people end up confused by an "Upgrade" button or surprised by a bill. Everything below is as of September 26, 2026.

Check that you can use AI Studio at all

Quotas don't matter until AI Studio opens for you. Google's available regions page names three reasons you might be turned away:

• Location. You need to be in a country or territory on Google's list. The US, the UK, EU countries, Japan, South Korea and Taiwan are on it. Mainland China, Hong Kong, Macao, Russia, Belarus and Iran are not.
• Age. The minimum age is 18.
• Age verification. An adult account can still be blocked until the age on the Google Account has been verified.

If you run code in Google Colab, the location check uses the region of the Colab instance, not your own.

If your country isn't on the list, stop here: there's no free AI Studio route for you. Google points those users to the Gemini API in Gemini Enterprise Agent Platform, a paid Google Cloud product rather than a free web playground. If you're in a listed country and API calls return 403 errors instead, that's a different problem, covered in Gemini API Key Permission Denied: Fix 403 by Error Source.

The three kinds of "free" in AI Studio

"Free tier" gets used for several different things. This table separates them.

Two rules follow from the table.

A subscription only works inside the website. Google's plans documentation says Google AI plan benefits for developers "apply only within the Google AI Studio web interface," and that direct API use "is billed and managed separately." If you pay for Google AI Pro and then call Gemini from a script, that script runs on the free or paid API tier like anyone else's.

The API tier follows the project, not the person. API keys inherit the billing status of the project they belong to. One Google account can have a free project and a paid project side by side, and AI Studio charges you based on which one's key you're using.

What changed on April 20, 2026

On April 20, 2026, Google said in a blog post on higher AI Studio limits for Google AI subscribers that "Google AI Pro and Ultra subscribers get increased usage limits in Google AI Studio," including "access to Nano Banana Pro and Gemini Pro models." The same post frames the subscription as a "low-setup billing bridge" for builders "who have exhausted their free-tier limits," while pay-per-request API keys "remain the standard for production-scale launches."

In practice, the free tier didn't disappear. It narrowed. The Free plan now means basic access with a modest quota, and Google names Gemini Pro, Nano Banana and Lyria as benefits of the paid plan. So if you pick Gemini Pro or Nano Banana and get an upgrade prompt, your account isn't broken. That's the paywall doing what it was designed to do.

If you remember AI Studio as a place to generate lots of images at no cost, that picture is out of date. On the current API pricing table, every Nano Banana model and Veo 3.1 are listed as "Not available" on the Free Tier, and Imagen no longer appears on the page.

Which models are free on an API key

Google publishes a model-by-model list only for the API. This is the Free Tier column of the Gemini API pricing page as of September 26, 2026:

This roster changes often, so treat it as a snapshot. It's also the API list, not a guaranteed list of what the website's Free plan shows. Google doesn't publish a model list for that plan, so the reliable check is to open the model selector in AI Studio while signed in with your own account.

API limits are counted per project, not per API key, so creating more keys in the same project doesn't add quota. Your active limits are shown in AI Studio. For the numbers and how they're counted, see Gemini API Free Tier 2026: Limits, Free Models, and Free API Keys.

What to do when the free quota runs out

You have three moves. The right one depends on where your work runs and which models you need.

Stay free

Google says AI Studio's daily limits are enforced with resets rather than rolling windows, so the allowance comes back after the reset. On the API side, requests-per-day quotas reset at midnight Pacific time. Limits also differ by model, so moving a task to a lighter free model such as a Flash-Lite version often keeps you going. If your code is getting 429 errors, Gemini API Rate Limits 2026: Free vs Paid Tier RPM, TPM, RPD walks through which limit you hit.

This is enough if you're learning, testing prompts, or building something small, and the free models do the job.

Subscribe to Google AI Pro or Ultra

This fits if you work in the browser, in the Playground or in Build mode, and you want Gemini Pro, Nano Banana or Lyria with a predictable monthly cost. You can upgrade from the Upgrade button in AI Studio's left navigation menu. On Google One's plans page, the US list price is $19.99 a month for Google AI Pro, and Google AI Ultra starts at $99.99 a month. Prices differ by country.

Know what a subscription doesn't cover before you buy:

• It doesn't make your API keys free or raise their limits.
• The Deep Research and Antigravity Preview agents in AI Studio still require a paid API key.
• Google One AI credits can't be used in AI Studio.
• When the subscription's daily quota runs out, Google's documented way to keep going is an API key on a project with billing enabled.

Link billing to an API project

This is the path for anything that runs outside the AI Studio website: your own scripts, an app other people use, production traffic, or models like Veo that have no free option. You start it from the Set up billing button on AI Studio's API keys or Projects page.

Some billing facts change the math:

• New users are generally placed on Prepay, which means buying credits first, with a minimum of $5 or the equivalent in your currency.
• The $300 Google Cloud Welcome credit can't be spent on the Gemini API or AI Studio if you opened your account after March 2, 2026. Since March 2026, Gemini API usage is excluded from the Cloud Free Trial.
• When a Prepay balance hits $0, every API key on that billing account stops working with an HTTP 402 error until you add credits.
• A new paid account starts at Tier 1, which has a $250 billing-account spend cap.

For per-token rates, see Gemini API Pricing 2026: Token Rates, Free Tier, and Key Cost. To create and lock down the key itself, see Google AI Studio API Key: Is It Free? Create, Secure, Verify.

A simple way to decide: if you only work in the browser and the free models are enough, stay free. If you work in the browser but need premium models, subscribe. If anything runs outside the browser or serves other people, link billing.

Make sure you're not paying by accident

Google's billing FAQ is direct about when AI Studio costs money: usage is free "unless users link a paid API key." Once you use a key from a paid project in AI Studio, you're charged for that key's usage. Run through these checks:

1. Look at the Plan column. On the API keys page in AI Studio, any project marked "Paid" under Plan has billing enabled.
2. Check which key you're working with. You switch between free and paid usage by choosing a key from a Free Tier project or a Paid Tier project. If you only meant to experiment, use the free project's key.
3. Set a spend cap. Project owners, editors and admins can set one on AI Studio's Spend page under Monthly spend cap, then Edit spend cap. Billing data can lag by about 10 minutes, and batch jobs or agent sessions can run past the cap, so leave some headroom.
4. Watch shared Build mode apps. When other people use an app you shared, their calls count against your limits, and paid models may cost you money. AI Studio warns you before sharing if an app could incur costs.
5. Go fully free again if you want. Disabling billing on a project returns it to the Free Tier. Do it for each project you want back on free.

What free usage means for your data

Free use isn't free of trade-offs. Google's pricing page lists "Content used to improve our products" as part of the Free tier, and each free model row says the same. On paid tiers, content isn't used that way.

There's one detail worth knowing. Your AI Studio prompts are covered by the "Paid Services" terms as long as at least one of your API projects has billing enabled, which is the same "Paid" label from the checklist above. Paying for Google AI Pro or Ultra isn't described as changing this. It's billing on an API project that does.

If you're working with client material, credentials, unreleased code or anything you wouldn't want used to improve a product, keep it out of a free session or move that work to a paid project.

Sharing and publishing Build mode apps

Build mode lets you describe an app and have AI Studio write it, and you can use it for free within your limits. Apps are private by default. When you share one, the people you share it with can use it, see its code and fork it. Your API key stays a server-side secret and isn't exposed to them.

To put an app on a public URL, Google's billing documentation says the Google Cloud Starter Tier lets you publish up to 2 full-stack applications without setting up a Google Cloud project or billing account. Past that, deploying to Cloud Run from AI Studio is the standard route, and Cloud Run pricing may apply.

FAQ

Is Google AI Studio fully free?

It's free to use if you're 18 or older, age-verified, and in a supported country, but it isn't unlimited. The Free plan has a modest daily quota. Premium models such as Gemini Pro, Nano Banana and Lyria need Google AI Pro or Ultra in the web app, or a paid API key.

Does a Google AI Pro subscription make my Gemini API key free?

No. Google AI plan benefits apply only inside the AI Studio website. API keys follow their project's tier: free if the project has no billing, paid if it does.

Did Google remove the AI Studio free tier?

No. On April 20, 2026, Google added higher limits and premium models for Pro and Ultra subscribers, and the Free plan became basic access with a modest quota. Free API access to Flash-class models, Gemini 2.5 Pro and Gemma 4 is still listed on the pricing page.

Can I generate images or video for free in AI Studio?

Don't count on it. On the API, every Nano Banana model and Veo 3.1 are paid only. In the web app, Nano Banana is one of the premium models Google lists as a Google AI Pro benefit. Google's plans documentation doesn't mention Veo as a subscription benefit.

Can I use Google Cloud's $300 credit or Google One AI credits?

For most people, no. The Google Cloud Welcome credit can't be used for the Gemini API or AI Studio on accounts opened after March 2, 2026. Google One AI credits aren't supported in AI Studio at all.

How do I use Google AI Studio for free?

Sign in at aistudio.google.com with an eligible Google Account, stay on the Free plan, and don't select a key from a project with billing enabled. For code, create an API key in a project without billing and stick to models marked "Free of charge" on the pricing page.
