Google announced Gemini 4 Argon on September 30, 2026, but it is not publicly available yet. Trusted cyber defenders in Google’s Fairwind Program are receiving the first access, alongside Google’s internal teams. Google says paid API customers and Google AI Ultra subscribers are next after additional safeguard work; it has not announced a date for that expansion or general availability.
Who can use Gemini 4 Argon now?
Access is currently limited to trusted cyber defenders selected through Google’s Fairwind Program and to Google teams using Argon internally. This is a controlled deployment, not an open developer preview or consumer release.
Google says the next phase will begin with paid API customers and Google AI Ultra subscribers. It then expects to move toward broader developer, enterprise and consumer access. The company has not provided a schedule for any of those stages.
Why are cyber defenders getting Argon first?
Google is positioning Argon as a model for long-horizon software engineering, enterprise work such as legal and finance, and cybersecurity defense. Its most consequential claimed capability is the ability to autonomously find, validate and patch critical software vulnerabilities.

- Unlocked Android phone gives you the flexibility to change carriers and choose your own data plan: Works with Google Fi, Verizon, T-Mobile, AT&T, and other major carriers[2]
- Stay informed without looking at your screen: When your phone is face down, Pixel HiLight gently alerts you with subtle glowing lights when your favorite contacts are calling or you’re talking with Gemini; exclusive to Google Pixel 11 Pro phones
- Magic Capture catches the moment as you live it: With just one tap, Pixel 11 Pro captures video and photos, and automatically edits, crops, and unblurs a curated collection, ready to share – and you get the memory of how it felt to be in the moment
- Two new cameras for more brilliant photos: A larger telephoto sensor captures 30% more light for clear, beautiful photos and videos, even in the dark[3]; Pixel’s longest zoom ever helps you capture details from impressive distances[4]
Cybersecurity is also a dual-use area: the same ability to discover weaknesses could help an attacker. Google’s staged approach lets experienced defenders test the model in real environments while the company continues to refine monitoring, misuse prevention and containment. Google DeepMind chief AI architect Koray Kavukcuoglu described the rationale plainly: “Safely releasing frontier capabilities at this level requires a phased approach.”
What Google says Argon can do
Vulnerability discovery and remediation
Google says Argon handled an internal vulnerability benchmark involving complex codebases across 20 programming languages. The announcement also says Argon outperformed Gemini 3.8 Flash Cyber on Wiz’s internal black-box penetration-testing benchmark, although it does not publish a score for that comparison. Wiz is using Argon through its Scan for Good initiative.
Rank #2
- Google Pixel 10a is a durable, everyday phone with more[1]; snap brilliant photography on a simple, powerful camera, get 30+ hours out of a full charge[2], and do more with helpful AI like Gemini[3]
- Unlocked Android phone gives you the flexibility to change carriers and choose your own data plan; it works with Google Fi, Verizon, T-Mobile, AT&T, and other major carriers
- Pixel 10a is sleek and durable, with a super smooth finish, scratch-resistant Corning Gorilla Glass 7i display, and IP68 water and dust protection[4]
- The Actua display with 3,000-nit peak brightness shows up clear as day, even in direct sunlight[5]
- Plan, create, and get more done with help from Gemini, your built-in AI assistant[3]; have it screen spam calls while you focus[6]; chat with Gemini to brainstorm your meal plan[7], or bring your ideas to life with Nano Banana[8]
Long-running software work
Google reports a 77.9% result on DeepSWE v1.1, which it describes as an evaluation of real-world, long-horizon software-engineering tasks. In one internal example, Google says Argon-assisted work made its libgav1 video decoder 2.7 times faster than an existing Rust port while producing identical video output. That is a specific decoder project, not a general promise that every software project will run 2.7 times faster.
Enterprise workflows and long-context output
Google reports 51.3% on AutomationBench, a Zapier evaluation of end-to-end execution across core business functions, and 91.7% on LVBench, its long-video-understanding evaluation. Argon’s maximum output length is reported as one million tokens, up from 64,000, which Google says is intended to support longer and more complex tasks.
Rank #3
- Google Pixel 10 Pro is the ultimate Pixel experience, featuring advanced AI with Gemini, unbelievable camera quality, impeccable design in two sizes, and the next-gen Google Tensor G5 chip[1]
- Unlocked Android phone gives you the flexibility to change carriers and choose your own data plan[2]; it works - Google Fi, Verizon, T-Mobile, AT&T, and other major carriers
- Get a head start on syncing your data before it even arrives: After you purchase your new Pixel, look for an email that explains how to transfer your photos, videos, passwords, and more in just a few quick steps[11]
- Pixel’s pro camera system makes everything look amazing, even in low light; capture more of the scene with advanced Google AI models, and bring out incredible details with 100x Pro Res Zoom, stunning 50 MP images, and super steady videos in 8K[10]
- Pixel 10 Pro is built with durable aluminum and Corning Gorilla Glass Victus 2 for scratch and drop resistance; the 6.3-inch Super Actua display with 3,300-nit peak brightness is easy on the eyes, even in direct sunlight[3,13,18]
Specialized technical optimization
Google says an Argon example involving quantum-subroutine resource optimization was 40% better than a published baseline. The announcement does not establish that this improvement transfers to unrelated scientific or engineering workloads.
Google’s published benchmark results
The figures below are results reported by Google in its September 30 announcement. The sources reviewed for this article do not include independent replication, so they should be read as company claims rather than verified industry-wide rankings.
| Evaluation or example | Figure reported by Google | What Google says it represents |
|---|---|---|
| DeepSWE v1.1 | 77.9% | Real-world, long-horizon software-engineering tasks |
| CWE-bench v1 | 68% | Tied for first on a vulnerability-remediation benchmark |
| AutomationBench | 51.3% | End-to-end execution across core business functions |
| LVBench | 91.7% | Long-video understanding |
| Maximum output | 1 million tokens | Expanded from 64,000 tokens for longer tasks |
| libgav1 example | 2.7× faster | Argon-assisted work compared with an existing Rust port, with identical video output |
| Quantum optimization example | 40% better | Improvement over a published baseline in Google’s example |
Google also reports freeing more than 300 TiB of memory after internal optimizations, with estimated total savings of 500 TiB to 1 PiB. Those are internal infrastructure figures, not a promise of equivalent savings for customers.
What safeguards are still being developed?
Google says it is continuing work in four areas before expanding access:
Free tools Windows power users keep installed
One-click scans. No signup required.

Google says internal and external red teams used manual and automated attacks to test these protections, but the announcement does not publish complete test results. For the initial trusted-defender and internal cohorts, Google says Argon will be released without cyber guardrails so defenders can exercise its defensive capabilities. That condition is specific to the controlled cohort and should not be read as a general-public policy.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.When will paid customers and the public get access?
| Stage | Who is included | Status |
|---|---|---|
| Initial rollout | Trusted cyber defenders in Fairwind and Google internal teams | Underway |
| Next expansion | Paid API customers and Google AI Ultra subscribers | Planned after further safeguard iteration; date not announced |
| Later expansion | Developers, enterprises and consumers | Planned direction; timing and terms not announced |
Google also says it is participating in the U.S. government’s voluntary process for pre-release model access. That participation is not a public approval, certification or safety endorsement.
How much will Argon cost?
Google says it has planned introductory and later API pricing for the broader rollout. The announcement summary does not state the figures or how long the introductory period will last. Because paid API and Ultra access are not yet open, any price should be checked against Google’s current product terms when access expands. The announcement does not provide full terms for the future subscription route.
What these claims establish—and what they do not
Argon’s launch establishes that Google is testing a frontier model with a deliberate cybersecurity-first release strategy. The published results indicate the areas Google considers important: software engineering, vulnerability remediation, business automation, video understanding and specialized technical optimization.
They do not independently establish that Argon is superior on every coding task, that its vulnerability patches are safe without human review, or that the reported internal productivity and infrastructure gains will occur in another organization. The benchmarks use different tasks and scoring methods, and several examples are demonstrations rather than broad production measurements.
