Google AntiGravity Pricing 2026: Is the Free Tier Enough?

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.

What's New as of June 2026

Two updates since the last revision matter for buyers. First, at Google I/O 2026 Google split Ultra into two tiers: a new $100/month Ultra with roughly 5x Pro quotas, and Ultra Max at $200/month (cut from $249.99) with roughly 20x Pro quotas. Same opaque credit system, lower entry point and a real price cut at the top.

Second, the legacy Gemini CLI is being retired on June 18, 2026. Google is asking users to migrate to the Antigravity CLI, which routes through the same credit pool as the IDE. If you depended on the old CLI's quotas, factor a Pro or Ultra subscription into your cost model. For an updated head-to-head, see our Cursor vs Google Antigravity comparison and the broader Google Antigravity tool page.

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. For context on what Gemini 3 Pro can build, our Kaggle hackathon report covers the December 2025 DeepMind event that put the model in front of developers.

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

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 ($100/mo) and Ultra Max ($200/mo): Restructured at I/O 2026

At Google I/O 2026, Google restructured the Ultra tier and cut the top price. The lineup is now:

• AI Ultra at $100/month: a new mid-tier with roughly 5x the Pro quotas. Aimed at developers who code daily but don't burn through Opus sessions back-to-back.
• AI Ultra Max at $200/month (down from $249.99): the old "Ultra" rebranded, with roughly 20x Pro quotas and the highest model access.

The price cut narrows the gap between Antigravity and a stack like Cursor Pro + Claude Code CLI for similar Claude/GPT access. But Ultra hasn't been immune to quota problems either. Since March 2026, even top-tier users have reported unexpected restrictions, and Google's documentation still does not publish per-model credit costs.

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

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. If you're choosing between AntiGravity and a conversational builder like Lovable, see our side-by-side in Lovable vs Google AntiGravity.

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 ($100/mo) and Ultra Max ($200/mo): More Competitive After the I/O 2026 Cut

The new $100 Ultra tier and the $200 Ultra Max (down from $249.99) make Antigravity easier to justify if you're already committed to the multi-agent workflow. Ultra Max at $200 is now within range of stacking Cursor Pro plus Claude Code CLI plus a Gemini subscription. Credit transparency is still missing, so treat the new prices as a discount on the same opaque system, not a fix.

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?

After Google I/O 2026, Ultra is now $100/month and Ultra Max is $200/month (down from $249.99). The price cut makes the top tier easier to justify, but even Ultra Max users have reported quota restrictions since March 2026. For many developers, splitting the budget across Cursor Pro, Claude Code CLI, and a Gemini subscription still 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 Cursor vs Google Antigravity 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.
