I would like to share with public for a permanent fix.

🚀 Proposed Fix: Resolving Rate Limiting by Removing AI Studio API Keys

Testing has confirmed a permanent solution for users experiencing "Free Tier" rate limits despite having a Pro or Ultra subscription.

📋 The Issue

When initializing the Gemini CLI for the first time, the system often generates or links an API Key from Google AI Studio. Because AI Studio operates on a separate "Pay-as-you-go" or "Free Tier" billing system, the CLI prioritizes the API Key's billing status (Free) over your actual Google account subscription status (Pro/Ultra).

🛠️ The Solution

If you are a paid subscriber, you do not need an API Key in the AI Studio Portal for the CLI to function. Removing it forces the CLI to authenticate directly via your account's subscription tier.

---

Steps to Fix

1. Revoke API Keys:
   • Go to Google AI Studio.
   • Locate any existing API Keys and delete/revoke them completely.
2. Resync the CLI:
   • Logout of the Gemini CLI.
   • Log back in to refresh your authentication token.
3. Verify Status:
   • The CLI should now bypass the AI Studio billing logic and correctly recognize your Pro or Ultra status, removing rate limits on high-end models.

---

Key Takeaways

• Billing Conflict: API Keys are tied to the AI Studio developer platform, which is distinct from Gemini consumer subscriptions.
• Rate Limits: Deleting the key prevents the system from defaulting to "Free Tier" limits.
• Subscription Priority: Once the key is removed, the system correctly defaults to your paid subscription level.

Important

Note: This is a permanent fix. If you create a new API Key in AI Studio for other projects, the CLI may begin reading that "Free" status again, requiring you to repeat these steps.

Did you ask AI for help with this? 🤣

In any case, I don't think it's accurate - I've got two keys on paid tier 2 with zero utilization in the last 30 days. Removing them doesn't do jack, nor should it if you're authenticated via oauth vs key. I'm also on Pro....

It's been working for me and a lot of people. We were able to use all models as no issues.
I only asked the AI to write a brief details instruction due to grammar.
I have been using Pro Preview 3.1 like no issues after I figured out because In AI Studio those are paid per billing which restricts your Tier to Free Level and not reading your account. I did some research off someone who decided to put credits from Pro, but revoking the API Access restores your account status instead pay per billing. It even explains in Gemini Cli Docs. Read this Post will explain why after the person use my method #24396 (comment)

Like 5 days ago various folks discovered signing out and back in with oath temporarily allowed at least a few prompts.

1. It's still insanely slow compared to how it used to be
2. It's NOT permanent, a reauth will only "work" for a bit
3. Your logic doesn't make sense for people who've got only paid tier API keys and are also pro/ultra subscribers

Stop and think about that last one for a minute 😉

this works for unlimited promps is what im trying to say. You don't need API key, Those API Keys are Paid Per Billing. Give it a try and see the results.

This user even confirmed working
@NexusRisen Confirmed that removing my AI Studio API Key/Project didn't affect or break my local Gemini CLI client (yet!). Not needing a key at all kind of makes sense after re-reading the Medium article:

"...Google has officially “graduated” the Google Developer Program (GDP) Premium tier by folding its high-value benefits directly into Google AI Pro and Google AI Ultra subscriptions as of January 27, 2026. Specific in the benefits were Google Cloud Credits that are now available to Google AI Pro and Google AI Ultra subscribers. The Cloud credits can be used to access Gemini API across tools like Gemini CLI, AGY etc."

The scope of credit availability is what's changed since January, not necessarily a sub's access to G-CLI. This definitely makes the more recent rate-limit errors sound more related to the mysterious authentication changes in the discussion post.

Note: This is a permanent fix. If you create a new API Key in AI Studio for other projects, the CLI may begin reading that "Free" status again, requiring you to repeat these steps.

Still some back-end nonsense!

Note: People got to read documentaries on what Google did with their changes. Google Gemini Cli will automatically read AI Studio API Key because of Google Credits. Removing API Key restores authentication and do not need to log out and log back in. It's indeed a perm fix. Then explain to me how myself and many users who did my method was able to use unlimited prompts and yet it's still blazing fast.

Like I said no issues.
If your on Paid Tier, you do not need API Key regardless.
And I kind of hate when people don't read how Google AI Studio works Here
