Gemini 3 Pro on Gemini CLI (Join the Waitlist)

We’re excited to bring Gemini 3 Pro to Gemini CLI. For Google AI Ultra users (Google AI Ultra for Business is not currently supported) and paid Gemini and Vertex API key holders, Gemini 3 Pro is already available and ready to enable. For everyone else, we’re gradually expanding access through a waitlist. Sign up for the waitlist now to access Gemini 3 Pro once approved.

Note: Please wait until you have been approved to use Gemini 3 Pro to enable Preview Features. If enabled early, the CLI will fallback to Gemini 2.5 Pro.

Do I need to join the waitlist?

Section titled “Do I need to join the waitlist?”

The following users will be automatically granted access to Gemini 3 Pro on Gemini CLI:

For Gemini Code Assist Enterprise users, access is coming soon.

Users not automatically granted access through one of these account types will need to join the waitlist. This includes Google AI Pro, Gemini Code Assist standard, and free tier users.

Note: Whether you’re automatically granted access or accepted from the waitlist, you’ll still need to enable Gemini 3 Pro using the /settings command.

How to join the waitlist

Section titled “How to join the waitlist”

Users not automatically granted access will need to join the waitlist. Follow these instructions to sign up:

  • Install Gemini CLI.
  • Authenticate using the Login with Google option. You’ll see a banner that says “Gemini 3 is now available.” If you do not see this banner, update your installation of Gemini CLI to the most recent version.
  • Fill out this Google form: Access Gemini 3 in Gemini CLI. Provide the email address of the account you used to authenticate with Gemini CLI.

Users will be onboarded in batches, subject to availability. When you’ve been granted access to Gemini 3 Pro, you’ll receive an acceptance email to your submitted email address.

How to use Gemini 3 Pro with Gemini CLI

Section titled “How to use Gemini 3 Pro with Gemini CLI”

Once you receive your acceptance email–or if you are automatically granted access–you still need to enable Gemini 3 Pro within Gemini CLI.

To enable Gemini 3 Pro, use the /settings command in Gemini CLI and set Preview Features to true.

For more information, see Gemini CLI Settings.

Usage limits and fallback

Section titled “Usage limits and fallback”

Gemini CLI will tell you when you reach your Gemini 3 Pro daily usage limit. When you encounter that limit, you’ll be given the option to switch to Gemini 2.5 Pro, upgrade for higher limits, or stop. You’ll also be told when your usage limit resets and Gemini 3 Pro can be used again.

Similarly, when you reach your daily usage limit for Gemini 2.5 Pro, you’ll see a message prompting fallback to Gemini 2.5 Flash.

Capacity errors

Section titled “Capacity errors”

There may be times when the Gemini 3 Pro model is overloaded. When that happens, Gemini CLI will ask you to decide whether you want to keep trying Gemini 3 Pro or fallback to Gemini 2.5 Pro.

Note: The Keep trying option uses exponential backoff, in which Gemini CLI waits longer between each retry, when the system is busy. If the retry doesn’t happen immediately, please wait a few minutes for the request to process.

Model selection & routing types

Section titled “Model selection & routing types”

When using Gemini CLI, you may want to control how your requests are routed between models. By default, Gemini CLI uses Auto routing.

When using Gemini 3 Pro, you may want to use Auto routing or Pro routing to manage your usage limits:

  • Auto routing: Auto routing first determines whether a prompt involves a complex or simple operation. For simple prompts, it will automatically use Gemini 2.5 Flash. For complex prompts, if Gemini 3 Pro is enabled, it will use Gemini 3 Pro; otherwise, it will use Gemini 2.5 Pro.
  • Pro routing: If you want to ensure your task is processed by the most capable model, use /model and select Pro. Gemini CLI will prioritize the most capable model available, including Gemini 3 Pro if it has been enabled.

To learn more about selecting a model and routing, refer to Gemini CLI Model Selection.
