Image: Google Google Antigravity's New Rate Limits Are Frustrating Developers: AI Credits, Weekly Caps, and the Pro Tier Squeeze
Google restructured Antigravity quotas around AI credit tiers, giving Ultra subscribers uncapped five-hour refreshes while Pro users hit weekly walls. Developers aren't happy.
Google announced changes to how Antigravity quotas work, and the developer response has been loud.
The announcement came via the @antigravity account on X on March 11:
“We’re evolving Google AI plans to give you more control over how you build. Every subscription includes built-in AI credits, which can now be used for Antigravity, giving you a seamless path to scale.”
The framing is about “control” and “seamless scaling.” In practice, it means Pro subscribers are running into weekly quota walls that didn’t exist before, and the path to keep working is to buy more credits or upgrade to the $249.99/month Ultra plan.
What Actually Changed
Google restructured Antigravity rate limits around its existing Google AI subscription tiers. Here’s the new system:
| Tier | Price | Quota Refresh | Weekly Cap | AI Credit Overages |
|---|---|---|---|---|
| Free (Google AI Plus) | $7.99/mo | Weekly | Yes | No |
| Google AI Pro | $19.99/mo | Every 5 hours | Yes, once reached, wait until next week | Optional ($25/2,500 credits) |
| Google AI Ultra | $249.99/mo | Every 5 hours | No weekly cap | Optional ($25/2,500 credits) |
The key detail is in the Pro tier. Quotas refresh every five hours, but only until you hit a weekly ceiling. Once you burn through the weekly allotment, the five-hour refresh stops and you wait until the following week. Or you toggle on “AI Credit Overages” and pay for additional credits at $25 per 2,500.
Ultra subscribers get the same five-hour refresh cycle but without a weekly cap. That’s the core difference between $20/month and $250/month.
All tiers retain access to the same features: Gemini 3 Pro, unlimited tab code completions, Agent Manager, and browser integration. The restriction is purely on how much agent compute you can use.
What Developers Are Saying
The Google AI Developers Forum and Reddit are full of complaints, particularly from Pro subscribers.
One user reported a dramatic drop: “Before January I could use over 300 million input / 1-2 million output in a week for the Gemini Pro models. This week I hit my weekly rate limits at less than 9 million input / 200 thousand output tokens.”
Other complaints from the forums and PiunikaWeb reporting:
- Pro users report their quotas showing as exhausted despite not using Antigravity for two days
- Claude Sonnet and Opus limits (Antigravity supports third-party models) appear depleted with minimal usage
- Some users can’t determine how quota was consumed, because Google hasn’t provided a detailed usage breakdown
- Multi-day lockouts once the weekly cap is hit, leaving developers unable to work
The comments under Google’s own announcement post tell the story. As PiunikaWeb put it: “the comments under it clearly show that people aren’t happy with the quotas.”
The Credit System
When your quota runs out, you have two options: wait for the next refresh, or spend AI credits.
AI credits are part of the broader Google AI subscription and can now be used across Antigravity. The pricing is $25 for 2,500 credits, charged through Vertex API rates. Google added a toggle in Antigravity’s settings: “Enable AI Credit Overages.” Set it to “Always” and you’ll automatically dip into purchased credits when your included quota runs out. Set it to “Never” and you’ll just wait.
What Google hasn’t clarified is exactly how many credits each Antigravity operation consumes. The plans documentation says “usage is correlated with the ‘work done’ by the agent; straightforward tasks consume less quota than complex reasoning,” but there’s no conversion table. Developers don’t have a reliable way to predict their costs, which is a big part of the frustration.
The Models in Play
Antigravity currently supports five models, and each has its own quota allocation:
- Gemini 3.1 Pro (High and Low modes)
- Gemini 3 Flash
- Anthropic Claude Sonnet 4.6
- Anthropic Claude Opus 4.6
- OpenAI GPT-OSS 120B
The third-party models (Claude, GPT-OSS) burn through quota faster than Gemini models. Google positions AI Pro as the tier for “hobbyists, students, and developers” who primarily use Flash models. If you’re regularly using Claude Opus or Gemini 3.1 Pro High through Antigravity, Google wants you on Ultra.
Context: Why This Is Happening
Google described user response to Antigravity as “incredible” when the original rate limit system launched in December 2025. Demand apparently exceeded internal projections. The new tiered system is Google’s attempt to manage that demand while monetizing heavy users.
This follows a pattern. Antigravity launched with generous free-tier access to drive adoption, and it worked. Now Google is tightening the supply side while pointing developers toward paid credits and the $250/month Ultra tier. It’s a familiar playbook in cloud services: grow fast with free tiers, then optimize for revenue once the user base is locked in.
The timing is also notable. The Register reports that the changes coincide with broader pushback on Google AI plan pricing, with users protesting what they see as a bait-and-switch on the value proposition.
How It Compares
For context, here’s how Antigravity’s quota structure compares to other AI coding tools with subscription-based access:
| Tool | Plan | Price | Rate Limit Model |
|---|---|---|---|
| Google Antigravity | Pro | $19.99/mo | 5hr refresh with weekly cap |
| Google Antigravity | Ultra | $249.99/mo | 5hr refresh, no weekly cap |
| Codex (ChatGPT Plus) | Plus | $20/mo | Included with subscription |
| Codex (ChatGPT Pro) | Pro | $200/mo | Higher limits |
| Claude Code (Max) | Max 5x | $100/mo | Included with subscription |
| Claude Code (Max) | Max 20x | $200/mo | Higher limits |
The $20/month tier comparison is where Antigravity’s Pro plan looks weakest. Both ChatGPT Plus and Claude Max 5x include their respective coding tools at that price point without weekly lockouts. Antigravity Pro gives you five-hour refreshes that stop once you hit a weekly wall, then charges extra for overages.
At the $250/month level, Ultra competes with ChatGPT Pro ($200) and Claude Max 20x ($200). Ultra does include access to third-party models through a single subscription, which the others don’t offer. Whether that’s worth the premium depends on how much you value model switching within one tool.
What to Do
If you’re on Antigravity Pro and hitting limits:
- Check your model usage. Third-party models (Claude, GPT-OSS) consume more quota than Gemini models. Switching to Gemini 3 Flash for less demanding tasks can stretch your allocation.
- Leave AI Credit Overages off until you understand the costs. Without a clear credit-to-token conversion, you risk unexpected charges.
- Batch your work. The five-hour refresh rewards concentrated sessions over sporadic use throughout the day.
- Evaluate alternatives. If you’re primarily using Claude models through Antigravity, a direct Claude Max subscription might give you better value with fewer restrictions.
Google is likely to adjust these quotas as they get feedback. The current limits feel like a first attempt at monetization rather than a settled policy. But for developers who built workflows around the old, more generous system, the transition is painful.
