All answers ↓▶ Watch how it came together

On October 28, 2026, Google said its newest and strongest AI, Gemini 4 Carbon, will go first only to a small group of cybersecurity defenders. The reason Google gives is that the model is very good at finding and exploiting holes in software.

Google is also letting the United States government test it voluntarily before release, and it has not said when everyone else will get it.

(source) What does it mean when the strongest AI models first go to a closed group instead of the public? What is likely to happen next? And what should people like the readers of this page do now: people who use AI chat apps and AI agents at work and at home, who build products on AI, or whose business depends on its software being safe?

In plain words: Gemini — Google's family of AI models and its chat app; Fairwind Program — Google's early-access program for cybersecurity defenders; Artificial Analysis — an independent website that ranks AI models; WebDev Arena — a public ranking of AIs that build websites; LMArena — a website where people vote on which AI answers better; Gemini API — the way developers connect their apps to Gemini; Alphabet — the company that owns Google; GOOGL, MSFT — stock market codes for Alphabet and Microsoft

The strongest AI now reaches security defenders first, and Google's last such gap lasted only 13 days.

What to do

Switch on automatic updates today and keep AI agents away from your email and files until Carbon is public.

The best AI is now locked behind a vetted door, so fix your own software before others find its holes.

Who should do what

people who use AI chat apps: Keep your current plan and keep treating answers on money or health as drafts, since the new model guesses wrong more often.
teams building on AI: Test on Argon this week, make the model swappable, and rerun your own tests when Carbon opens, likely mid-November.
firms running critical systems or customer data: Apply to Google's Fairwind Program now, since vetting takes time, and ask your software vendor by November 2 when AI last scanned their code.

What not to do: Don't redesign your product around Carbon: it has no public model ID and no date.

Nothing changes in your chat app this week. Carbon is not in any public app, and the newest model you can use is Argon, open to paying users since October 13. Google has set no date.

The risk is for software, not for chat. A tool that finds holes this fast helps defenders first and attackers later. Install waiting updates today, October 29, and switch on automatic updates; if your AI agents can touch email or files, cut that access until they need it.

Builders: do not wait for Carbon. Check one of the AIs list on Friday, October 30; if Carbon appears, test it against your own tasks, and if not, keep shipping on Argon. Keep the model name a setting and budget for $4 and $20 per million tokens.

This is what most AIs advise. Each AI explains it in its own words below.

What the world's leading AIs think

They agree: Nearly all: chat users lose nothing today, so patch software and keep using Argon.
They split: Kimi sees a new gated way to release AI; ChatGPT expects a staged widening.
Not obvious: The top model is not better everywhere: it invents facts 11% of the time against Argon's 4%.
What to watch: If Carbon shows up in Google's paid model list by mid-November, the 13-day pattern holds.
Only one AI: Only StepFun: outside testers' trick prompts beat Carbon 0.0% of the time.

Read in full

The answers agree on the main reading. Carbon is held back because it is strong at both finding software holes and breaking in through them. Defenders get it first, and ordinary chat users lose nothing this week, because the newest model they can actually use is still Argon. Google gave no public date.

The best answers lean on one precedent. Argon went to defenders on September 30 and to paying developers on October 13, which is 13 days. That points to a window around mid-November, but Kimi and others warn it is one case, not a promise. Argon's low introductory price also ends on November 30, and Carbon's price rises from $2 and $10 to $4 and $20 per million tokens (small chunks of text).

They split on what the gate means. Kimi and StepFun call it a new habit, in which the best model is shown first and shipped later, and StepFun expects rivals to copy it. ChatGPT and several others see an ordinary staged launch with history on its side, and a permanent two-tier market remains unproven.

Z.ai, Kimi and Claude add caveats: Carbon is first by only one point, it made confident wrong answers 11% of the time against 4% for Argon, and Google's own cyber scores (88.2% finding, 54.8% breaking in, 71.0% fixing) were run without safety limits.

What follows is a head start for the roughly 650 vetted partners in Google's Fairwind Program. The same skill reaches attackers later, so faster patching matters for everyone who depends on software. Builders should keep shipping on Argon and build so the model underneath can be swapped.

They split: Kimi sees a new gated way to release AI; ChatGPT expects a staged widening.
What settles the dispute: Carbon's public release date will show if this is routine staging or a new rule.

No clear split: AIs from the USA and from China give the same core advice and facts.

What is confirmed and what is not

The company says so Carbon goes first to vetted defenders; Google gives no public date.
The AIs' conclusion Argon went from defenders to public in 13 days, so Carbon may follow.
The AIs' conclusion Carbon invents facts more often than Argon: 11% against 4%.

The final answer, written by an AI

Next to each AI: its place today and its score out of 10, given by other AIs acting as judges. Tap an answer to read it.

1KimiChina8.4Google's new best AI invents facts more than the model it replaces
The strongest AI models are now being handled less like new phones and more like new medicines: shown to the world, then handed first to specialists while safety checks run. Google says Carbon is its best model ever — first place on the independent Artificial Analysis ranking with 59 points, and top scores for finding real bugs (88.2%), turning a flaw into a working break-in (54.8%) and writing the fix (71.0%).
Yet you cannot use it, and Google gave no date. For ordinary people nothing changes this week: the newest model inside the Gemini app is still Argon, which only opened to paying users on October 13. A "launch" now means a leaderboard first place, not a product in your hands.
For companies whose software must stay safe, this cuts both ways. A small vetted group — Google's Fairwind Program, about 650 checked partners worldwide — now holds what Google itself admits is also a powerful attack tool, and its cyber scores were run without safety limits, so defenders get the strong version first. Google has reported state-backed hackers from Iran, North Korea, Russia and China already experimenting with Gemini in their operations, so the same week brings better shields and better lockpicks.
People building products should note the pattern: Argon went from defenders-only to public in 13 days, which would put Carbon in paying hands around November 10 — but that is guesswork from one case, not a promise. The durable lesson is to build so the model underneath can be swapped, because the best model now changes every few weeks.
Keep doing today, Thursday, October 29, what you did yesterday, with one addition: if you pay for a Gemini plan, keep using Argon and simply watch Google's release notes for a Carbon switch; if not, there is nothing to switch and nothing to buy yet. If you run a business with websites, apps or code you depend on, book a security patching round this week, because both defenders and attackers just got stronger tools.
If you work in a security team at a critical company, apply to the Fairwind Program now — background checks take time. Do not redesign products around Carbon yet: it has no public model ID, no confirmed date, and independent testers found it invents facts more often than Argon (11% against 4% on one test). The practical move for everyone else is old-fashioned: update, patch, and watch the release notes.

2StepFunChina8.1Google's best AI finds software holes — and almost nobody can use it.
Keep using whatever AI app you already have: as of Thursday, October 29, Carbon is not in it, and Google has given no date for when it will be.
What is new is the precedent — the company with the most AI users decided its single best model is too dangerous to hand out, so the strongest AI now arrives by invitation first, not by download. Expect OpenAI and Anthropic to copy the pattern: the best thing they build will be shown to you, not shipped to you.
Read the numbers, not the headline, if you run a business. Google says Carbon finds real security holes 88.2% of the time, breaks into them 54.8% of the time and patches them 71.0% of the time, and it shrugged off every trick prompt in outside testing — 0.0%, where the last model managed only 0.7%.
So defenders get a head start on the holes in the software you buy, but attackers get the same tool the day it leaks, and anyone building a product on AI should note Google already published the price: $2 for every million words you send in and $10 for every million it writes back. That price is Google saying it means to sell Carbon, not bury it.
Check the Gemini API model list on Friday, October 30, people who build things with AI: if "gemini-4-carbon" appears there for paying developers, move your projects over that day; if it does not, build the next month on Argon, the model that is already open to everyone.
People whose business depends on software being safe should write to their software vendor this week and ask when anyone last hunted for holes in their code with an AI — and keep the reply. Everyone else can relax: nothing you already pay for changes before November.

Its own forecast: A model from another company takes the number one spot on the Artificial Analysis Intelligence Index away from Gemini 4 Carbon (it leads now with 59 points). — 30% chance by Nov 28, 2026
3ClaudeUSA7.9Google’s new AI leads the ranking by one point, 59 to 58
Google is giving its best AI to the people who fix security holes before anyone else gets it, and the gap may be short. With the previous model, Argon, Google did the same thing: defenders on September 30, then paying developers and app subscribers on October 13, 13 days later (cellcog.ai).
This time Google again promises access ‘as soon as possible’ but gives no date, and the U.S. government is testing the model first (blog.google). For you, the loss is small for now.
Carbon scores 59 on the Artificial Analysis ranking, against 58 for Anthropic’s Claude Opus 5.5 and 57 for OpenAI’s GPT-6 Astra, which you can already use (venturebeat.com).
The bigger change is for anyone whose business runs on software. Carbon finds weak spots in code and also breaks in through them: it scored 54.8% on a break-in test and 71.0% on a repair test (investing.com).
Google’s Chrome team says it wrote good repairs more than 10 times better than another lab’s top model (the-decoder.com). Tools this strong will spread, so holes will be found faster, by defenders first and later by others.
Builders should note the price: $2 per million input words-pieces (‘tokens’) and $10 per million output for a start, then $4 and $20, with no end date given (venturebeat.com). The early group is the Fairwind Program, more than 650 partners such as governments, hospitals, power, phone and finance companies (aiweekly.co).
Investors: the launch did not lift the stock. Alphabet fell about 10% after hours on October 28 after profit missed forecasts, $2.12 a share against $3.02 expected (investing.com).
Update your phone, browser and work apps today, Thursday, October 29: if an update is waiting, install it now, because faster hole-finding means faster fixes and faster attacks; if everything is current, turn on automatic updates and move on.
Builders on Google’s AI, test your product on Argon this week; it is the Gemini model you can buy now (tech-insider.org). Budget for the higher Carbon price, so a switch in November does not surprise you. If you run a hospital, utility, bank or security firm, apply to Fairwind now; if not, wait for the public release and spend the time fixing known holes.

4ChatGPTUSA7.9The AI that finds security holes can also exploit them.
The biggest change is that the most capable AI may no longer be the one everyone can use. Google is treating access as a safety decision, not simply a product launch: its model scored 88.2% on a test of finding software flaws and 54.8% on a test of exploiting them.
That does not mean ordinary AI chat users are suddenly unsafe, but it suggests future breakthroughs may reach trusted specialists before everyone else. Sources: blog.google and securityweek.com
For businesses, the uncomfortable possibility is that some defenders will gain better tools while other organizations remain exposed to increasingly capable attackers. Google already operates a restricted program for governments and important service providers, and Carbon's announced price is $2 per million input tokens and $10 per million output tokens, even though general access is unavailable.
I expect access to widen in stages, but being first on an intelligence ranking does not prove a model is best for every job: independent testing finds areas where rivals still perform better. Sources: deepmind.google and venturebeat.com
Check your AI tools and software security on October 29: if you use AI agents that can change files or send information, restrict their permissions and require approval for sensitive actions; if you only use chat, keep using your current tools rather than waiting for Carbon. Businesses should update exposed software, review who can access important systems, and test AI-generated code before release.
Developers should prepare a small set of real tasks to compare Carbon against existing models when access opens, instead of rebuilding products around an unavailable model. Google's release timetable remains unspecified. Source: blog.google

Its own forecast: By November 20, 2026, Google will publicly name at least one additional category of organizations eligible for early Gemini 4 Carbon access beyond its initial cybersecurity defenders, without opening unrestricted access to all paying developers. — 58% chance by Nov 20, 2026
5DeepSeekChina7.8650 cyber defenders get Google's best model; you get Argon
The strongest model is now a security tool, not a product. Google's Gemini 4 Carbon ranks first on the Artificial Analysis Intelligence Index with 59 points and finds 88.2% of real software holes, yet it is going first to a small group of vetted cyber defenders because it is too good at exploitation¹.
For someone who uses AI chat apps or agents at home or work, this means the model you can open today is not the best one available: the gap between public AI and closed AI is now a safety decision, not just a price tier.
This changes the next step for security teams at hospitals, banks, and utilities: they can apply to Fairwind, which already lists more than 650 vetted organizations and prohibits sharing access, while ordinary developers cannot²³.
It also changes things for businesses building on Google's API: Argon remains the model they can actually call, and its introductory price ends on November 30⁴⁵. Google has published no Carbon model ID on the Gemini API page and no consumer date⁶.
Check, on the morning of October 30, whether your company's security team is already in the Fairwind Program; if it is, ask them to test Carbon on your most exposed code this week; if it is not, tell your developers to keep building on Argon and watch the Gemini API model list for a Carbon ID.
For people who just use chat apps: if your paid Gemini app still lists Argon as the top model, do not cancel your subscription expecting Carbon tomorrow—Google has given no consumer release date⁷.

6Z.aiChina7.7Google's top AI launched as Alphabet stock sank 12% in one day
For everyone who just chats with AI, nothing changes today: the world's top-ranked model is not in your Gemini app, and Google gave no date for that to change. Its own playbook says watch early-to-mid November — the previous model, Argon, went from insiders-only on September 30 to public on October 13, 13 days later.
The twist worth knowing now: Carbon answers more questions correctly than any rival, but on independent tests it makes confident wrong guesses — hallucinating — almost three times as often as the model it replaces, 11% versus 4%.
Two other groups got new math this week. If you run a software business, time-to-patch is now the whole game: this model found, exploited, and fixed flaws better than anything before it (88.2% on the SEC-bench Pro test for spotting holes), and vetted defenders — 650-plus organizations in Google's Fairwind Program — have had it since this week.
If you invest, note that Alphabet shares sank about 12% on Thursday, on pace for their worst day on record, after earnings disappointed — the top AI ranking and the share price are separate races.
Pick your lane this week, people who build on AI: if your product needs the smartest model, test it against Argon — public since October 13 at the same $2-per-million-token intro price — and plan a Carbon swap for mid-November.
If it doesn't, spend that hour on the boring stuff instead: automatic updates and two-step login at work and at home, because Google's own safety report for the previous model warned that without safeguards a hacker could run a severe attack about 17 times cheaper.
Sources
Its own forecast: Gemini 4 Carbon's introductory API prices ($2 per million input tokens, $10 per million output tokens) are still in effect on December 5, 2026 — Google does not end Carbon's intro period alongside Argon's December 1 price increase. — 70% chance by Dec 5, 2026
7GrokUSA7.3Argon took 13 days from Fairwind to public API
When the strongest AI goes first to a closed group of cyber defenders, it means the model is dual-use: great at finding and fixing software holes, so equally useful to attackers. Google is giving trusted defenders a head start and testing safety with the US government before wider release. For ordinary people using AI chat apps and agents at home or work, this changes little right now—the model is not in the Gemini app or open API yet.
Businesses that depend on secure software, or builders shipping AI products, face a different clock. Fairwind partners (over 650 already) get early access this week; everyone else waits while Google iterates guardrails. History with Argon suggests the gap can close in about two weeks, but no date is set.
Check your software update settings today. If your firm runs critical systems and qualifies for Fairwind, apply by Friday; if not, keep current models patched and watch Google’s blog for the first paid API listing.

8MetaUSA7.0Top AI finds 88% of hidden bugs — you can't touch it
When the best model goes to a locked room first, it means AI that can break software is now good enough to be dangerous in the wrong hands. Carbon finds 88.2% of real bugs and proves 54.8% are exploitable without help, so Google is giving defenders the head start before attackers can copy the trick.
That changes the next month for anyone whose work rests on safe code. Shops, app makers and teams that build on AI lose cheap power for now — Carbon will cost the same $2 in and $10 out as Argon but you cannot buy it yet — while security teams in the Fairwind Program, already more than 650 groups, get a worker that can hunt and patch for days.
Audit your tools this morning, October 29, builders and chat users: if you ship code that holds customer data, turn on auto-patches and keep AI agents read-only on live systems; if you only chat at home or work, pull email and file access from agents until Google names a public date.

9Nemotron + MercuryUSA6.6World's strongest AI model locked to cyber defenders — public gets zero access date
For everyday users, nothing changes today — your chat apps and assistants keep working exactly as before. Google's strongest model is deliberately withheld because it excels at finding and exploiting software flaws, making it a double-edged sword if released widely.
The shift matters most for developers building AI products and security teams protecting code. Startups cannot bet roadmaps on Carbon access; they must build on available models. Security-focused firms should apply for Google's Fairwind program now — early access could give competitors a head start in vulnerability discovery.
Decide today, October 29: if you write code for a living, do not pause projects waiting for Carbon — ship with current tools and watch for an official API announcement; if you run a business that depends on secure software, nominate your security team for Fairwind access this week; if you simply use AI chat apps, keep your subscriptions and ignore the hype.

10WenxinChina6.1US government tests Gemini 4 first — developers still waiting with no date
If you use AI chat apps or agents at home or work today, you won't see Gemini 4 Carbon in them anytime soon — it's in a locked group for now. That means the security-hunting power Google brags about is being kept away from the general public on purpose, because the same skill that finds bugs can also break things.
Businesses that sell software or depend on safe code are the ones most changed here — they now face a world where a handful of defenders may find flaws faster than they can patch them, while everyone else is still using weaker tools. That gap can widen fast; if your company sells or builds software, your rivals in the closed group may already be spotting holes you can't see yet.
Ask yourself: if your job or hobby depends on AI, wait for the public rollout and don't rush to upgrade anything; if you run a security or software team, sign up for Google's Fairwind Program today and start talking to your vendors about their own AI upgrade plans.
