Google AntiGravity Pricing (2026): Free Tier, Credits & the Lockout Problem
TL;DR
Everything you need to know about Google AntiGravity pricing in 2026.
- Free tier: All models with rate limits, quota refreshes roughly every 5 hours
- Paid plans: AI Pro ($20/mo), AI Ultra ($249.99/mo)
- Credits: $25 for 2,500 AI credits, but credit-to-token conversion is undisclosed
- Best for: Developers evaluating AntiGravity costs before subscribing (and wondering about the lockout reports)
If you're researching Google AntiGravity pricing before subscribing, fair warning: this is one of the more confusing pricing structures in the AI coding space right now. We break down every tier, explain the credit system (as much as Google has disclosed), and cover the quota controversies that have defined AntiGravity's pricing story in 2026.
Is AntiGravity Free?
Yes. AntiGravity has a free tier with access to all supported models:
- Gemini 3.1 Pro (High and Low variants)
- Gemini 3 Flash
- Claude Sonnet 4.6
- Claude Opus 4.6
- GPT-OSS 120B
No credit card needed. You get rate-limited access that is supposed to refresh approximately every 5 hours until you hit a weekly ceiling.
The reality is more complicated. Since December 2025, the free tier has been cut repeatedly, and many users report that the 5-hour refresh cycle doesn't work as advertised. If you're evaluating AntiGravity, the free tier is enough to test the multi-agent workflow, but don't expect to use it as a daily driver.
All Plans Compared
| Plan | Price | Credits | Models | Best For |
|---|---|---|---|---|
| Free | $0/mo | Rate-limited | All models (limited access) | Testing the IDE |
| AI Pro | $20/mo | Built-in (amount undisclosed) | All models (higher limits) | Hobbyists and students |
| AI Ultra | $249.99/mo | Built-in (amount undisclosed) | All models (highest limits) | Heavy daily usage |
| Pay-as-you-go | $25 per 2,500 credits | 2,500 per purchase | Full model access | Overflow / burst usage |
Free Tier: Test It, Don't Rely On It
The free tier gives you access to every model AntiGravity supports, which is genuinely impressive. You can assign different models to different agents within the same mission (e.g., Gemini for planning, Claude for coding, GPT for review).
The problem is reliability. Google has cut free tier quotas four times since December 2025:
- Dec 2025: Requests per day slashed from 250 to 20 (92% reduction)
- Dec 2025: Requests per minute dropped from 10 to 5
- Feb 2026: Image generation quotas tightened
- Mar 2026: AI Credit system introduced, changing how all usage is metered
Use the free tier to learn the interface and run a few test missions. For real work, you'll hit limits quickly.
AI Pro ($20/mo): The Obvious Choice (With Caveats)
Pro is positioned for "hobbyists, students, and developers who live in the IDE." You get higher quotas, built-in credits, and access to all models with fewer restrictions than the free tier.
At $20/month, it matches Cursor Pro and GitHub Copilot on price. The pitch is that you get multi-model access (Gemini, Claude, GPT) in one IDE instead of paying for each separately.
The caveat: multiple Pro users have reported 7-day and even 10-day lockouts when their quota runs out. One developer documented a single Claude Opus 4.6 session consuming 635 out of 1,000 credits. That means one or two complex coding sessions can trigger a lockout for the rest of the week.
AI Ultra ($249.99/mo): Premium Price, Unclear Value
Ultra costs more than 12x the Pro tier and promises "consistent, high-volume access to our most complex models." It includes the most built-in credits and the highest rate limits.
At $249.99/month, Ultra is the most expensive AI coding subscription on the market. For context, you could get Claude Pro ($20), Cursor Pro ($20), and GitHub Copilot ($10) with $200 left over for API credits.
Even Ultra hasn't been immune to the quota problems. Since March 2026, Ultra users have reported unexpected quota restrictions, which is especially frustrating at this price point.
The Credit System Explained (Sort Of)
In March 2026, Google introduced AI credits as the usage currency for AntiGravity. Here's what we know:
- Cost: $25 for 2,500 AI credits
- Per credit: $0.01 each
- Subscriptions include built-in credits (exact amounts for Pro and Ultra are not publicly documented)
- Additional credits can be purchased on top of your subscription
Here's what Google has not disclosed:
- Credit-to-token conversion rate: How many tokens does one credit buy? Unknown.
- Per-model credit costs: Does a Claude Opus request cost more credits than a Gemini Flash request? Likely, but not documented.
- Subscription credit amounts: How many built-in credits do Pro and Ultra include? Not publicly listed.
This opacity is the core complaint from the developer community. You can't do cost planning when you don't know what a credit buys you. Google's own documentation includes the disclaimer: "Specified rate limits are not guaranteed."
The Quota Controversy: What Actually Happened
AntiGravity launched in November 2025 as a free agent-first IDE with generous quotas. Then the cuts started:
Phase 1 (Dec 2025): Free tier gutted. Requests per day dropped from 250 to 20. The community noticed immediately but accepted it, since most SaaS products tighten free tiers after launch.
Phase 2 (Feb 2026): Image and specialized quotas tightened. Less visible, but affected users building multimodal workflows.
Phase 3 (Mar 2026): Credit system replaces quotas. This is where it got contentious. Google moved from (vague) quota guarantees to an explicit credit-based system. In practice, this meant:

- Input tokens went from ~300M weekly to under 9M weekly for some users (97% reduction)
- Output tokens dropped from 1-2M weekly to ~200K weekly
- The advertised "5-hour refresh" cycle didn't match real-world behavior
- Even paying users experienced multi-day lockouts
The community response was sharp. Posts about AntiGravity being a "paperweight" spread across X and developer forums. The Register covered the backlash. Google's developer forums saw threads titled "CRITICAL BUG: AI Credits update completely broke baseline quotas."
Where things stand now (April 2026): The credit system is still in place. Google has made incremental adjustments, but the fundamental transparency issues remain. If you're subscribing, go in with realistic expectations about quota limits.
How AntiGravity Pricing Compares
| Tool | Price | What You Get | Quota Clarity | Best For |
|---|---|---|---|---|
| AntiGravity Free | $0 | All models, heavy rate limits | Low | Testing agentic workflows |
| AntiGravity Pro | $20/mo | Higher limits, built-in credits | Low | Occasional multi-agent use |
| AntiGravity Ultra | $249.99/mo | Highest limits | Low | Heavy agentic use (if you trust the quotas) |
| Cursor Pro | $20/mo | Claude, GPT, custom models | High | Daily IDE coding |
| GitHub Copilot | $10/mo | GPT-based completions | High | Inline code completion |
| Claude Pro | $20/mo | Claude Sonnet/Opus | High | Reasoning-heavy coding |
| Z.ai Lite | ~$10/mo | GLM-5.1, GLM-4.7 | Medium | Budget API coding |
AntiGravity's unique advantage is multi-model, multi-agent coordination in a single IDE. No other tool lets you assign Claude to one agent and Gemini to another within the same workflow. Whether that's worth the pricing uncertainty depends on how central agentic workflows are to your process.
Should You Pay for AntiGravity?
Free Tier: Yes, for Evaluation
The free tier is the right starting point for everyone. Test the multi-agent architecture, run a few missions, and see if the workflow clicks for you. Don't commit money until you understand how your usage maps to credit consumption.
AI Pro ($20/mo): Maybe, With Eyes Open
If you've tested the free tier and want more headroom, Pro makes sense at $20/month, but only if you accept the quota uncertainty. Set up a secondary coding tool (Cursor, Claude Code) as a fallback for when you hit lockouts.
AI Ultra ($249.99/mo): Hard to Recommend Right Now
At nearly $250/month with undisclosed credit amounts and no guaranteed rate limits, Ultra is a tough sell. The money would go further split across multiple tools with transparent pricing. If Google publishes clear credit-to-token conversion rates and resolves the lockout issues, this calculus could change.
Alternative Approach: Free Tier + Separate API Access
Some developers use AntiGravity's free tier for its multi-agent UI while routing actual model calls through their own API keys (Anthropic, OpenAI, or Z.ai). This gives you the agentic workflow without depending on AntiGravity's credit system. Check the AntiGravity documentation for current API key configuration options.
Cost-Saving Tips
1. Use Gemini Flash for Routine Tasks
Gemini 3 Flash is the cheapest model in AntiGravity's lineup. Route planning, summarization, and simple code generation through Flash and save your credit budget for Claude Opus or Gemini Pro on complex tasks.
2. Monitor Your Credit Consumption
AntiGravity doesn't make this easy, but track how many credits each mission type consumes. One complex Opus session can burn through your weekly budget. Know your patterns before they surprise you.
3. Set Up a Backup Tool
Given the lockout reports, having a secondary coding tool is practical, not paranoid. Cursor at $20/mo or Claude Code as a CLI option both work as reliable fallbacks.
4. Avoid Opus for Exploratory Work
Claude Opus 4.6 produces the best results but consumes credits fastest. Use Sonnet or Gemini Pro for exploration and iteration. Switch to Opus only when you need its reasoning depth for a specific, well-defined task.
Frequently Asked Questions
Is Google AntiGravity free?
Yes. The free tier includes all models (Gemini 3.1 Pro, Claude Sonnet 4.6, Claude Opus 4.6, GPT-OSS 120B) with rate limits. No credit card needed. Quotas refresh periodically, though the actual refresh cycle has been inconsistent since March 2026.
How much does AntiGravity Pro cost?
AI Pro costs $20/month. It includes built-in credits and higher model access limits than the free tier. Exact credit amounts included with Pro are not publicly documented.
What are AI credits?
AI credits are AntiGravity's usage currency. They cost $25 for 2,500 credits ($0.01 per credit). Credits are consumed when you use AI models within the IDE. The credit-to-token conversion rate is not disclosed by Google.
Why do people call AntiGravity a paperweight?
After the November 2025 launch with generous free quotas, Google progressively cut limits and introduced an opaque credit system. Users who relied on AntiGravity for daily coding found themselves locked out for days at a time, making the IDE unusable. The "paperweight" label stuck in community discussions.
Can I use my own API keys in AntiGravity?
Check the current documentation for API key configuration options. Some users route model calls through their own Anthropic, OpenAI, or other API accounts to avoid depending on AntiGravity's credit system.
Is AntiGravity Ultra worth it?
At $249.99/month, Ultra is the most expensive AI coding subscription available. It offers the highest limits, but even Ultra users have reported quota restrictions since March 2026. For most developers, splitting that budget across multiple tools with transparent pricing delivers more predictable value.
How does AntiGravity compare to Cursor on price?
Both offer a $20/month tier. Cursor Pro gives you clear usage limits, SOC 2 certification, and mature IDE features. AntiGravity Pro gives you multi-model, multi-agent workflows with less pricing transparency. Cursor is the safer bet for daily reliability. AntiGravity is the more experimental choice. See our full comparison.
Do AntiGravity credits roll over?
Google's documentation does not clearly state whether unused credits expire. This is another area where the pricing transparency falls short.
Last updated: April 2026. Pricing and features are subject to change. Google's credit system and quotas have changed multiple times since launch. Check the official AntiGravity pricing page for current information.
