Rate limits and model availability differ based on your Google AI plan. Refer to Models for a breakdown of model availability.

All plans receive the following baseline features:

• Use of Gemini models, including Gemini 3.1 Pro, Gemini 3.8 Flash, and other offered Gemini Enterprise models as the core agent model

Users on Google AI Ultra receive the following benefits:

• The highest, most generous quota, refreshed every five hours
• The highest weekly rate limits
• Access to third-party models

Users on Google AI Pro receive the following benefits:

• A high, generous quota, refreshed every five hours until the weekly limit is reached

• A meaningful quota, refreshed weekly
• A weekly rate limit

The baseline rate limits are primarily determined by available capacity and exist to prevent abuse. Under the hood, the rate limits correlate with the amount of work done by the agent, which can differ from prompt to prompt. As a result, you receive more prompts when your tasks are straightforward and the agent can complete the work quickly, while more complex tasks consume more quota.

Usage limits for this service are subject to modification. These adjustments may be necessary to manage system capacity and maintain service stability.

Users on Google AI Pro or Ultra plans can use purchased AI credits (or any one-time promotional credits) for additional overage usage above the baseline quota. AI credits are consumed at standard Gemini Enterprise consumption pricing.

Once you exhaust the baseline quota for a particular model, credit usage is controlled by the AI Credit Overages user setting, which you can set to one of the following options:

• Never: Never use AI credits automatically; wait until the baseline quota refreshes before using this model further.
• Always: Always use AI credits when the baseline quota is exhausted (automatically switches back to using the baseline quota once it refreshes).

You can view baseline quota usage across models on the Settings page.

There is currently no support for the following options:

• Bring-your-own-key (BYOK) or bring-your-own-endpoint for additional rate limits
• Organizational tiers through a custom contract
