Google made several AI-centric announcements at the I/O 2026 conference yesterday, including a significant price reduction for its AI Ultra plan, now slashed by $50. However, the company also quietly introduced a new $100 per month AI Ultra plan that sits between the original $200 and the $20 Pro plans, offering fewer perks and lower limits. More controversially, Google has imposed stricter usage limits on its AI Pro plan without fanfare, switching to a credit system based on compute usage rather than simple token counts.

What's Changing in the AI Pro Plan

Earlier today, an email from Google revealed the new policy for AI Pro subscribers. The company is transitioning to a credit system where each prompt consumes credits based on "the complexity of your prompt, features you use, and the length of the chat." This marks a departure from the previous flat token limit approach. While Google claims this is a fairer mechanism that charges for actual computational resources used, users on Reddit have reacted angrily, with some calling the system "a total scam." One user reported that a single text prompt burned through 13% of their quota, suggesting the new system may heavily penalize even simple interactions.

Additionally, Google is adopting a rolling five-hour window for usage restrictions, similar to Anthropic's Claude plans. Credits refresh after each five-hour cycle until the weekly limit is reached. These limits are not confined to Gemini but also apply to other AI products such as Antigravity and Flow. The company is also discontinuing the 1,000 free AI credits previously given for Flow, although it claims the user experience should remain unchanged. Users can monitor their credit consumption through the Usage limit option in Gemini's settings. Google has not specified the exact number of tokens or credits available to Pro users, only stating that they are four times that of the free tier.

Background and Context

Google's AI subscription ecosystem has evolved rapidly since the launch of Gemini Advanced (now known as AI Pro) in early 2024. The original plan offered extensive features including integration with Google Workspace, expanded context windows, and priority access to new models. However, as competition intensified, especially with OpenAI's ChatGPT Plus and Claude Pro, Google began adjusting tiers and pricing. The I/O 2026 announcements were meant to simplify the lineup, but the quiet imposition of usage limits on the mid-tier plan has drawn criticism.

The new credit system is reminiscent of usage-based billing models seen in cloud computing. Instead of a simple cap on tokens, credits reflect the actual server load generated by each prompt. This allows Google to better manage resources but introduces unpredictability for users. A short query might cost less than a few credits, but a complex multi-turn conversation involving file uploads or code execution could exhaust the quota quickly. The five-hour window mechanism also creates a rolling soft cap, meaning heavy users could hit their limit multiple times per day.

These changes come just days after Google was spotted testing weekly limits on some accounts, which have now been confirmed. Industry analysts note that Google's move mirrors similar actions by Anthropic, which introduced a five-hour rolling window for Claude Pro in early 2025 after users abused unlimited access. OpenAI also introduced usage caps for ChatGPT Plus in late 2024, though they are based on message limits per three-hour period. The trend indicates that as large language models become more popular, providers are seeking ways to control costs while maintaining subscription revenue.

Critics argue that Google's approach lacks transparency. The company did not announce the AI Pro plan changes at the I/O keynote, only sending out emails to existing subscribers after the fact. The terms of service also allow Google to modify usage limits without prior notice, leaving users vulnerable to sudden reductions. Some subscribers have reported that their effective monthly allowance has decreased by over 50% compared to the previous token-based system.

Key Facts at a Glance

• Google slashed the AI Ultra plan price by $50 and introduced a $100 Ultra plan with lower limits.
• The AI Pro plan now uses a compute-based credit system instead of token caps.
• Credits are consumed based on prompt complexity, features used, and chat length.
• One Reddit user claims a single text prompt used 13% of their quota.
• Usage is restricted with a five-hour rolling window; limits refresh after each cycle until the weekly cap is reached.
• The new limits apply to Gemini, Antigravity, and Flow products.
• Google discontinued the 1,000 free Flow credits, saying user experience should not change.
• Users can track credit usage via the Gemini settings menu.
• Exact credit/token numbers are undisclosed; Pro gets four times the free tier allowance.
• Limits are subject to change without notice.

User Reactions and Implications

The response from the AI community has been largely negative. On platforms like Reddit, Hacker News, and Twitter, power users have expressed frustration over the lack of clarity and the perceived reduction in value. A thread on r/GoogleGemini titled "Google AI Pro is now a scam" accumulated hundreds of comments within hours. Many users reported that tasks that previously used 10% of their daily token allowance now consume 30–40% of the credit quota. Some have threatened to cancel subscriptions and switch to alternatives such as Claude Pro or Perplexity Pro.

From a business perspective, Google's changes could backfire. The AI Pro plan is aimed at developers, researchers, and early adopters who rely on predictable pricing. The switch to a compute-based credit system introduces uncertainty, making it harder for users to budget their usage. Furthermore, the fact that these changes were communicated quietly suggests that Google anticipated pushback. The company may be testing the waters to see how many subscribers churn before adjusting policies.

Comparisons with competitors highlight differences in transparency. Anthropic clearly states the number of messages allowed per five-hour window for Claude Pro, while OpenAI shows a character-based limit for ChatGPT Plus. Google's refusal to publish exact credit numbers makes it difficult for users to evaluate the plan. The company's assertion that "you have four times the allowance of the free tier" is vague because the free tier limits are also opaque.

Looked at historically, Google has often adjusted its AI pricing and features quietly. In late 2024, it reduced the context window of Gemini Advanced from 1 million tokens to 128k tokens without fanfare. That move also sparked criticism, but subscriber numbers remained stable. This pattern suggests Google is willing to endure short-term backlash in favor of long-term cost optimization. However, the AI market is more competitive now, with players like Meta's Llama and open-source models offering alternatives that run on local hardware.

What This Means for Subscribers

For current AI Pro subscribers, the new system requires careful monitoring. The Usage limit option in Gemini's settings provides real-time credit consumption data, but without a clear conversion to expected usage per task, users must rely on trial and error. Google's support documentation has not been updated with examples, leaving many to infer limits through community spreadsheets.

Developers who use the API through the Pro plan may also be affected. The same credit system applies to Antigravity and Flow, which are used for AI-assisted coding and data analysis. Heavy users of these tools could find their productivity bottlenecked by the rolling five-hour windows. Google recommends that power users consider upgrading to the $100 Ultra plan, which offers higher limits, but many feel that is an upsell rather than a solution.

The discontinuation of 1,000 free Flow credits removes a perk that helped new users experiment with the tool. While Google says the removal won't affect experience, existing Flow users have reported that their ability to run complex notebooks or processing tasks has been curtailed. The company may eventually introduce a standalone Flow subscription, but no details have been announced.

Given that usage limits can change without notice, subscribers should regularly check their account settings and watch for emails from Google. The company has a history of grandfathering some features during transitions, but it is unclear if that will happen here. As the AI landscape evolves, users may need to evaluate whether Google's ecosystem offers enough value to justify the unpredictable costs.
