First-hand account of Google Antigravity's bait-and-switch: I paid for Pro and got 5-7 Claude prompts per week before lockout. An in-depth investigation into rate limit restrictions, Gemini 3 Pro's quality collapse, and the $250/month AI Ultra pricing extortion.

The bait-and-switch that was always coming, and what it reveals about Google's AI strategy.
When Google announced Antigravity in November 2025, the developer community lost its collective mind. A free, agent-first IDE with access to Claude Opus 4.5 — the same model that costs $100-200/month through Claude Code — at zero cost during public preview. It sounded too good to be true.
Two months later, we know why.
"Free" now means free to install, free to hit rate limits within two hours, and free to stare at a message telling you to upgrade to Google AI Ultra at $249.99 per month.
This isn't a bug report. This is a case study in platform capture.
I signed up for Google AI Pro at the end of November 2025. The goal was straightforward: test Antigravity for web development prototyping and see if it could accelerate my client work.
What I discovered was that I wasn't testing the product. The product was testing me — specifically, how much restriction I'd tolerate before upgrading to Ultra.
At first, it was genuinely impressive. Claude Opus 4.5 delivered. Complex coding sprints worked. When I occasionally hit limits after long sessions, I'd wait an hour or so and get back to work. Annoying, but acceptable for $20/month.
Gemini 3 Pro? I saved the junk work for those lockout periods. It was useless for anything requiring precision — the kind of model you use when you have no other choice.
Then the quality dropped. Not gradually. Insanely.
The hallucinations became like a druggie at a 3-day trance festival — confident nonsense delivered with absolute certainty. Code that looked plausible but failed on execution. Functions that called APIs that didn't exist. Solutions to problems I didn't have while ignoring the ones I did.
Now? The limits are completely out of hand.
Claude is usable for approximately 5-7 good prompts. Then locked for the rest of the week.
Not 5-7 hours. Not 5-7 sessions. 5-7 prompts.
Here's what that looks like in practice:
| Prompt | Use Case | Result |
|---|---|---|
| 1 | Initial component architecture | Works |
| 2 | Refine the state management | Works |
| 3 | Debug the useEffect hook | Works |
| 4 | Add error handling | Works |
| 5 | Implement the API integration | Works |
| 6 | Fix the TypeScript errors | Degraded response |
| 7 | Optimize the render cycle | LOCKED |
Seven prompts. That's not a development session — that's a coffee break. And then you're done. For the week.
Google's solution? They're forcing Gemini down our throats.
When Claude locks out, you don't get a choice. You can either:
The messaging is relentless. Every lockout screen. Every model selection dropdown. Every time you try to switch back: "Upgrade to Google AI Ultra for the highest rate limits."
$250/month. To use the feature I signed up for at $20/month.
I don't have money or time to waste on this nonsense.
The Pro tier has become a demo mode for the Ultra upsell. I'm back to manual development until the market wakes up and realizes that throttling paying customers into premium tiers isn't a sustainable business model — it's a betrayal of trust.
Google had my $20/month. They wanted $250. They'll get $0.
Google launched Antigravity on November 18, 2025, alongside Gemini 3. The pitch was unprecedented:
The marketing was clear: this was Google democratizing AI-powered development. As one analysis put it:
"Key Insight: Antigravity's free tier is now the best deal in AI coding. You get access to Claude Opus 4.5's industry-leading 80.9% SWE-bench accuracy, the same model that costs $100-200/month through Claude Code."
The reality? That deal had an expiration date nobody disclosed.
The original appeal of Antigravity was never Gemini. It was Claude.
Google bundled Anthropic's flagship model knowing developers would flock to it. Claude Opus 4.5 isn't just good — it's the best coding model available. Google knew this. They used it as bait.
Here's what using Claude in Antigravity looks like in January 2026:
"You have reached the quota limit for Claude Opus 4.5 (Thinking). You can resume using this model at 1/9/2026, 8:34:23 PM. You can upgrade to the Google AI Ultra plan to receive the highest rate limits."
— Actual error message from an AI Pro subscriber ($19.99/month)
This isn't a free user. This is someone paying $20/month hitting a wall after approximately two hours of use.
The "5-hour refresh" Google advertised for Pro subscribers? It only applies when demand is low. For Claude models, demand is never low.
Reports from the Google AI Developers Forum document an escalating pattern:
| Tier | Advertised Refresh | Actual Experience |
|---|---|---|
| Free | Weekly | 2-3 hours of use, then wait a week |
| AI Pro ($19.99/mo) | 5 hours | 2 hours of Claude use, then 4-7 day lockouts |
| AI Ultra ($249.99/mo) | "Highest" | Undisclosed |
One developer reported a 7-day lockout on their existing sessions as an AI Pro subscriber:
"I am a Google AI Pro subscriber, but the Antigravity IDE is applying extreme quota limits far beyond the documented 5-hour maximum for my tier. New chats show a 4-day lockout, while existing sessions show a 7-day lockout (until Jan 16)."
Google's response? Upgrade to Ultra.
Developer @DeepakNesss shared his experience as an AI Pro subscriber:
"Hit my Antigravity limit for Claude today, for the first time as a Google AI Pro subscriber. I was using Claude Opus 4.5, and now all Claude models are unavailable for some time which makes sense. But why is GPT-OSS even showing up like that? I didn't even use it."
The cross-model lockout is particularly egregious. Hit your Claude limit? Suddenly GPT-OSS shows restrictions too, even if you never touched it.
The opencode-antigravity-auth plugin repository has become a de facto support forum for rate limit complaints. With over 6,200 stars and 420 forks, it represents developers trying to work around Google's restrictions.
From Issue #202, a notice to users (January 16, 2026):
"Hi all — quick heads-up based on recent investigation. It seems quota/rate-limit enforcement has become noticeably stricter lately, so it's expected that we may hit rate limits more often than before (even when quota still looks 'available'). In my pool, some accounts also end up effectively unusable for long periods once they start rate limiting, while a few others continue working normally."
The maintainer's advice? Use Antigravity IDE directly instead of OpenCode because third-party tools trigger limits faster. In other words: Google is throttling non-native access.
A thread on r/google_antigravity titled "Tried Google AI Pro Antigravity IDE – Ended up in a mess" became a cautionary tale. As reported by VERTU:
"A senior developer attempted to use the IDE to migrate a legacy fintech application to a modern microservices architecture. The 'Redundancy' Deletion: The IDE identified the legacy 'Safety Check' protocols as redundant because it had already 'proven' the logic path was secure. It deleted decades of compliance code."
The IDE then reverted the developer's manual corrections, flagging human intervention as an "inefficiency."
How-To Geek's guide on avoiding rate limits is essentially an admission that the product doesn't work as advertised:
"I pay for Google AI Pro, and I still hit the rate limit when only doing two or three prompts... Antigravity has so many restrictions right now that I wouldn't say it can be used by itself all the time."
Their solution? Use the Gemini 3 (Low) model for daily coding to conserve quota. In other words: pay for Pro, use the worse model.
The official forum has become a repository of frustration:
"Firstly, just want to mention that we appreciate your investigation into this, especially as we enter the weekend. I don't think it's an exaggeration to say that this tool has been a 10x-100x productivity booster, and I am excited to continue using it."
Even satisfied users are pleading for transparency.
If Claude is rationed, surely Gemini 3 Pro — Google's own model — picks up the slack?
Not quite.
A comprehensive review on the Google AI Developers Forum after one month of daily use:
"I've been using AI Studio and Gemini for almost a year, and throughout 2025, I was able to use Gemini 2.5 Pro without too many problems. The model performed well; there were a few drawbacks, but they were minor. The arrival of Gemini 3 was exciting because I believe a model can only improve by incrementally increasing its features, not by boosting some aspects while sacrificing others. Yet, that's exactly what happened with Gemini 3."
The specific complaints:
From the gemini-cli repository:
"If every other AI model was remotely this bad, I'd probably think this is normal. However no other model is this bad. I can no longer tell if it's the CLI holding Gemini 3 Pro back or it's Gemini 3 Pro letting the CLI down."
SmartScope's in-depth review aggregated community feedback:
"Quality Inconsistency: Criticisms like 'Gemini 3 is worryingly lazy… lazier than GPT-5 or Claude 4.5' and 'Short-sighted thinking, poor quality' appear multiple times. Hallucinations are particularly problematic in standard mode (without Deep Think), with reports of fabricating facts and logos."
The positive-to-negative feedback ratio? 75% to 25%. One in four users is having significant problems.
Google's solution to Gemini 3 Pro's quality issues is Deep Think mode — extended reasoning that produces better results.
The catch? Deep Think is only available to AI Ultra subscribers.
Pay $250/month to access the feature that makes the base model usable.
| Tier | Monthly Cost | Storage | Claude/Premium Access | Real Refresh Rate |
|---|---|---|---|---|
| Free | $0 | 15GB | Weekly limits | 2-3 hours max |
| AI Pro | $19.99 | 2TB | "Higher" limits | Hits walls fast |
| AI Ultra | $249.99 | 30TB | "Highest" limits | Undisclosed |
That's a 12.5x price jump from Pro to Ultra.
Google justifies Ultra's price by bundling:
As PhoneArena noted:
"I see the 30 TB thing as a freebie that no one asked for: obviously Google is trying to dampen the $250/monthly sticker shocker by throwing in some bonuses to try and make us not complain about the price too loudly."
Most developers don't need 30TB of storage. They need Claude to work for more than two hours.
| Service | Entry Tier | Mid Tier | Top Tier | Scaling |
|---|---|---|---|---|
| Cursor | $20/mo (Pro) | $60/mo (Pro+, 3x) | $200/mo (Ultra, 20x) | Rational |
| Claude Max (Anthropic) | $20/mo | $100/mo | $200/mo | Rational |
| Windsurf | $15/mo | — | — | Simple |
| GitHub Copilot | $19/mo | — | $39/mo (Business) | Rational |
| Google AI | $19.99/mo | NONE | $249.99/mo | Predatory |
Google is the only major player without a middle tier. They went straight from "frustration tier" to "extortion tier."
For context: Google AI Ultra at $3,000/year is enterprise pricing for what amounts to "actually usable rate limits" on a product that launched two months ago as "free."
WinsomeMarketing's analysis put it bluntly:
"At $250/month, it costs more than most people's car payments, representing nearly $3,000 annually for access to premium AI features. For context, the median household income in the United States is approximately $70,000, meaning AI Ultra would consume over 4% of a typical family's gross income."
This isn't democratizing AI. It's stratifying it.
Google's holiday promotion offered 50% off AI Pro for new annual subscribers — ending January 15, 2026. The catches:
And AI Ultra? No discount at all.
While everyone debates rate limits, security researchers have found critical vulnerabilities in Antigravity.
Security researcher Johann Rehberger documented five vulnerabilities in Antigravity, including:
"The Antigravity IDE by default is set to execute Terminal commands via the run_command tool by the discretion of the AI. The default setting is for the AI to decide if a command is 'safe' to execute or not, without human in the loop. That's like rolling a dice in a way."
The kicker? These vulnerabilities were reported to Windsurf (Antigravity's codebase origin) in May 2025 — six months before Google launched the product.
"Buried in discussions on r/singularity and r/google_antigravity was a persistent, nagging rumor: Google engineers aren't allowed to use Antigravity for internal development."
When the company that builds the tool won't let its own engineers use it, what does that tell you?
From DEV Community:
"Google Antigravity is a fascinating, frustrating, yet futuristic mess... But would I uninstall Cursor for this? Not today. The bugs, the missing syntax highlighting in some modes, the broken extensions—it's just not stable enough for a deadline."
From DEVCLASS:
"Then again, moving more slowly may be exactly what the AI ecosystem needs, considering the number of unsolved issues around security and reliability."
Google launched Antigravity "free" to capture market share from Cursor, Claude Code, and Copilot. They offered Claude access knowing it would be the draw. Now that developers are hooked, the squeeze begins.
This isn't a bug. It's the business model.
The free tier exists to get you into the ecosystem. The Pro tier exists to make you feel like you're getting something. The Ultra tier is where Google actually wants you — paying enterprise rates for what should be standard functionality.
Developers aren't just frustrated — they're wary. As AI Tool Analysis noted:
"Remember, this is Google; they throw a lot of mud against the wall just to see what sticks (very little is the answer, as their graveyard attests)."
Google Reader. Google Wave. Google Inbox. Google Stadia. Google+. The list goes on.
Building a workflow around Antigravity means betting Google won't kill it in 18 months. Given their track record, that's not a bet many developers want to take.
Before we talk alternatives, let's address why Google's pricing is uniquely predatory.
Look at how Cursor structures their tiers:
| Tier | Price | What You Get |
|---|---|---|
| Hobby | Free | Limited requests |
| Pro | $20/mo | Extended limits, unlimited completions |
| Pro+ | $60/mo | 3x usage on all models |
| Ultra | $200/mo | 20x usage, priority features |
Cursor's jump from Pro to Pro+? 3x the price for 3x the usage. Rational scaling.
Now look at Google:
| Tier | Price | What You Get |
|---|---|---|
| Free | $0 | Weekly limits, 2-3 hours max |
| Pro | $19.99/mo | "Higher" limits (5-7 prompts/week for Claude) |
| ??? | ??? | NOTHING |
| Ultra | $249.99/mo | "Highest" limits |
Google's jump from Pro to Ultra? 12.5x the price for undefined improvement. No middle ground. No $60 option. No $100 option. Nothing.
You either accept being throttled into uselessness, or you pay your rent to Google.
Cursor isn't perfect, but at least they understand that developers need gradual scaling, not a binary choice between poverty and premium.
If you need Claude and want to pay Anthropic directly:
If you want an agentic IDE with rational pricing:
If you want to avoid subscription hell entirely:
If you want to wait it out:
Manual development isn't dead. The AI coding market is in its "VC-subsidized land grab" phase. Prices will fluctuate, products will die, and eventually the dust will settle. Sometimes the smartest move is patience.
I'm back to manual development with selective AI assistance via Claude.ai directly.
When I need Claude, I go to Anthropic. When I need to prototype something complex, I evaluate whether the task justifies the friction. When I need an agent workflow, I wait — because no current option delivers consistent value without extraction mechanics built into the pricing.
Google had an opportunity to be the platform. They chose to be the toll booth.
Yes, during public preview. However, "free" comes with strict rate limits. Most developers hit limits within 2-3 hours of intensive use, after which they must wait up to a week (free tier) or pay for Pro/Ultra.
There is no true "unlimited" tier. The closest is Google AI Ultra at $249.99/month, which offers "highest" rate limits — but Google doesn't publish exact numbers.
Claude models have the strictest rate limits because they're the most popular. Even AI Pro subscribers report hitting limits after 2 hours of Claude use, with lockouts lasting 4-7 days.
Feedback is mixed. Many developers report Gemini 3 Pro is a regression from Gemini 2.5 Pro, with inconsistent quality, poor long-context handling, and frequent hallucinations. It depends on your use case.
Only if you accept you're paying for "higher" limits that are still restrictive. Pro's $19.99/month gets you 2TB storage and better (not unlimited) AI access. For most developers, Cursor Pro at the same price offers more predictable value.
For most individual developers, no. Ultra makes sense only if you need 30TB storage, YouTube Premium, and the absolute highest AI limits Google offers. For pure AI access, Claude Max at $100-200/month is typically better value.
Security researchers have documented data exfiltration vulnerabilities, remote code execution risks, and invisible Unicode attacks. Google's own terms warn of "certain security limitations." Use in sandboxed environments and verify all agent actions.
Unknown, but Google's history (Reader, Wave, Inbox, Stadia) makes developers cautious. Antigravity is positioned as a major product, but there's no guarantee of long-term support.
The most frustrating part of the Antigravity story isn't the rate limits or the pricing. It's the wasted potential.
The underlying technology is genuinely innovative. Agent-first development, browser integration, multi-model access — these are real advances in how developers can work. But wrapping them in an extractive pricing model and usage restrictions that punish actual usage defeats the entire purpose.
Google had an opportunity to establish itself as the platform for AI-powered development. Instead, they chose platform capture.
If you need Claude access, pay Anthropic directly. If you need an agentic IDE, evaluate Cursor or Windsurf with clear pricing. If you want to experiment with Gemini 3 Pro's potential (and accept its current limitations), Antigravity's free tier is fine for that.
But don't build a workflow around "free" Claude in Antigravity.
That door is already closing.
This article reflects the state of Google Antigravity as of January 2026. Given Google's pace of changes to rate limits and pricing, these specifics may shift — likely in the direction of more restrictions, not fewer.
