Gemini Advanced but Deep Research Is Missing? Here Is the Fix

You upgraded to Gemini Advanced, or the Google One AI Premium plan, expecting to use Deep Research for serious work. You open Gemini, check the model selector, and nothing. No Deep Research option. In some cases, image generation and Gemini Live are gone too.

It feels like you are still on the free tier, even though your payment went through.

The good news is that in most cases, this is not a bug and not a random outage. It is usually a safety and compliance issue, and there is a very specific way to fix it.

In this guide, you will see why Deep Research is missing, how age verification works behind the scenes, and the exact steps to unlock the full Gemini experience you paid for.

The Problem: You Paid for Gemini Advanced but Got a Lite Experience

Here is the typical story.

You sign up for Gemini Advanced or Google One AI Premium, you get the confirmation email, and you can open Gemini without any issues. On paper you have access to the most powerful models, including Deep Research.

Then you open the interface:

• The model selector only shows standard models.
• The Deep Research option is nowhere in the dropdown or tools menu.
• It looks exactly like the free version of Gemini, even though your card has been charged.

If you are in the UK, Europe, Canada or another regulated region, this is very often linked to one thing: Google does not fully trust your age yet.

Symptoms That Your Gemini Account Is Locked Down

If Gemini feels stuck in a basic mode, check if these match your situation:

• You have an active Gemini Advanced or Google One AI Premium subscription.
• You can use standard Gemini, but Deep Research is missing from the model dropdown or the Tools menu.
• Other powerful features, like image generation and Gemini Live, are not available either.
• You are based in the UK, the European Economic Area, Canada, or another region with strict age rules for online services.
• Your Google account shows your real birthday, for example 25 or 35 years old, but you have never formally verified your age.

If several of these points are true, your account is very likely treated as unverified, which is effectively the same as being under 18 for sensitive AI features.

The Real Cause: An 18 Plus Safety Gate and Age Verification

The most capable Gemini models, especially the ones used for Deep Research and advanced image generation, can browse the web, combine multiple sources and generate complex content with relatively few guardrails.

Because of that, Google treats those features as 18 plus in many regions. If your account is not clearly verified as an adult, Gemini will quietly hide options like Deep Research, even if you are paying for the top tier.

There are two types of age on your Google account:

• Declared age
  The birthday you typed when you created the account.
• Verified age
  The age Google has confirmed using an ID or a payment method that meets legal requirements.

If you have only ever declared your age, your profile can still be treated as unverified. From the system's point of view, that looks the same as a minor. The result is simple:

• Gemini deep research missing
• Deep research not showing in Gemini
• Image tools and some live features hidden for safety reasons

To unlock them, you need to move from declared age to verified age.

Step by Step Fix: How to Unlock Deep Research

The fix is straightforward once you know where to look. You do not need to contact support or cancel your plan. You just need to complete age verification and refresh Gemini.

Step 1: Check Your Age Status

Go to the dedicated age verification page for your Google account:
Google age verification

Sign in with the same Google account you use for Gemini Advanced.

What you will typically see:

• If your age is already verified, the page will say so and you can move on to the refresh step.
• If not, you will be prompted to confirm you are over 18 by using a payment method or uploading identification.

If the page is prompting you, your account is not considered fully verified yet, no matter what birthday is set.

Step 2: Verify With a Card or an ID

You will usually have two main options.

Option A, recommended for a fast Gemini age verification fix: Use a credit or debit card

• Google performs a small authorization, often zero or a very small temporary hold, to confirm you have a valid adult payment profile.
• Once approved, your age is verified automatically.
• In most cases this is instant, so you can unlock Deep Research in minutes.

Option B, slower but still valid: Upload an ID

• You upload a photo of your government ID, such as a passport or driver license.
• A human or automated system checks it.
• This can take longer, often up to 24 hours or more.

Other Options,

• You can perform any other age verification method provided by google on that page.

If you want Deep Research back quickly, Option A is usually the better route.

Step 3: Do a Hard Refresh of Gemini

After verification, your account is upgraded internally, but your browser may still be holding on to an older, restricted view of Gemini.

To force a clean refresh:

1. Log out of all Google services in your browser.
2. Clear cookies and cache for Google and Gemini, or open a fresh Incognito or Private window.
3. Go back to Gemini and sign in again with your verified account.
4. Open Gemini Advanced or the plan page you are paying for.

In many cases, at this point you will see:

• A Deep Research option in the model dropdown.
• Additional tools that were previously missing, like image generation.
• In some regions, a clearly labelled Deep Research model, for example a variant of Gemini 1.5 Pro.

If Deep Research is now visible, you are done. Your account moved from a restricted mode to the full version you expected when you subscribed.

Other Reasons Deep Research Might Still Be Missing

If you have verified your age, refreshed the browser and Deep Research is still not available, there are a few other things to check before you assume it is a bug.

You Are on a Workspace Account With Admin Restrictions

If you are using Gemini through a Google Workspace account from work or school, your administrator can restrict which Gemini features are enabled.

In that case:

• Personal accounts may get Deep Research.
• Workspace accounts can be limited to safer or region specific models.

If Deep Research works on your personal Gmail account but not on your company address, it might be an admin policy rather than a product issue.

You Are Hitting Limits or Temporary Controls

From time to time, certain features are capped or adjusted for quality and safety reasons. It is possible to see Deep Research available at one time, then temporarily restricted or harder to access during a rollout or experiment.

This is less common than age verification issues, but it does happen. If you have checked age, account type and country, a temporary rollout or limit is another possible explanation.

Summary: Turn Gemini Back Into the Pro Tool You Paid For

It is incredibly frustrating to pay for a premium AI plan and still feel like you are stuck with a lite version. When you see Gemini deep research missing from the model selector, it is easy to assume something is broken or that you bought the wrong tier.

In reality, the most common cause is simple:

• Your account is treated as under 18 or unverified, so deep research is not showing in Gemini, along with other sensitive features.

The fastest way to fix it is:

1. Check your status on the Google age verification page.
2. Verify your age with a card for an instant upgrade, or upload an ID if needed.
3. Log out, clear cookies or use Incognito, then sign back in to Gemini and open your paid plan.

Once your age is verified and the interface is refreshed, the Deep Research option should appear, and you can finally use the full set of tools you were expecting from Gemini Advanced and Google One AI Premium.
