When deploying continuous AI watchdogs and running daily marketing automations, compute cost is a critical scaling bottleneck. The recent updates to Google Antigravity pricing represent a highly welcome shift. Previously, builders had to choose between the entry-level $20/month Google AI Pro plan (ideal for quick tests) and the $250/month Google AI Ultra plan (best for full daily operations). Google has now filled the gap, providing more flexible options for developers and e-commerce brands scaling up their agentic systems.
New Pricing Structure & Rates
The primary change is the introduction of a new mid-range Ultra tier at $100/month and a price drop for the top-tier Ultra plan from $250 to $200/month. The key details of the updated plans are shown in the comparison table below:
| Plan (Monthly) | Price | Rate Limit Multiplier | AI Credits |
|---|---|---|---|
| Google AI Pro | $20 / mo. | 1x (Base) | Removed from base (overage only) |
| Google AI Ultra (New) | $100 / mo. | 5x compared to Pro | Bonus $100 (expires May 25, 2026) |
| Google AI Ultra (Max) | $200 / mo. (reduced from $250) | 20x compared to Pro | Bonus $100 (expires May 25, 2026) |
Google has also simplified subscriptions by removing AI credits from the base plans, adjusting the base model entitlements upwards instead. AI credits will now function purely as an overage mechanism if you hit your limit.
Shared Pool: Gemini Flash and Gemini Pro Merged
From my perspective as an AI and PPC specialist, the most important improvement is the consolidation of rate limits for Gemini Flash and Gemini Pro into a single pool. Rather than enforcing independent caps, your usage is drawn down according to real-time API pricing. Since Gemini Flash is 8x cheaper than Gemini Pro, you can consume 8x more tokens on Flash compared to Pro, or combine them as needed. This brings three major advantages to daily workflows:
- Targeted model selection: Use the cheap Gemini Flash for continuous site audits and 404 checks.
- Deep reasoning on demand: Allocate the shared pool to Gemini Pro when the agent needs to handle complex API integrations.
- Lower overhead: Avoid paying for unused rate limits on a model you don't need for a specific project.
How the New Pricing Policies Optimize Marketing Budgets
By optimizing rate allocations, e-commerce brands can run more advanced automations without worrying about agents stopping mid-update. Cost predictability is vital for scaling marketing workflows.
Real-world experience
Before this update, one of our automated client accounts frequently hit the Gemini Pro limit during heavy API refactoring tasks, while our Gemini Flash rate limit sat completely untouched. Merging the quotas allowed us to smoothly complete the entire development loop, leveraging 100% of our purchased capacity.
Action Plan for Switching to the New Plans
If you already use Antigravity, I recommend completing these configuration checks to start saving money immediately.
Key Optimization Actions:
- Review usage: Assess if the new $100 Ultra tier provides sufficient limits for your needs compared to the top tier.
- Redirect API calls: Move simple monitoring scripts to Gemini Flash, reserving Pro quotas for reasoning-heavy tasks.
- Set spend caps: Configure hard limits for overage fees inside your Google Cloud Console.
Frequently Asked Questions (FAQ)
What happens when I hit my shared quota limit?
Once you exceed your quota, API calls are charged as overage based on real-time token pricing, unless a hard limit is set in your billing settings.
Who gets the $100 bonus credit?
The bonus credits are automatically applied to new and existing Ultra plans activated by May 25, 2026, valid for 12 months.
Can I use experimental models in the Ultra plan?
Yes. The shared pool supports Gemini Flash and Pro. Experimental and Nano models may be subject to separate quotas.
