Google announced Gemini 4 Argon on September 30, 2026, and is first rolling it out to trusted cyber defenders through its Fairwind Program. Google teams also use the model internally. Broader access is planned to begin with paid API customers and Google AI Ultra subscribers after further safeguard work, but Google has not announced a date.
Who can use Gemini 4 Argon now?
At launch, access is limited to trusted cyber defenders selected through Google’s Fairwind Program, alongside Google’s own internal teams. This is a controlled rollout, not a generally available product. Google says it is also participating in the U.S. government’s voluntary process for pre-release model access; that does not amount to public approval, certification, or a safety endorsement.

Google DeepMind SVP and Google Chief AI Architect Koray Kavukcuoglu announced Argon on September 30, 2026. In the announcement, he wrote: “Safely releasing frontier capabilities at this level requires a phased approach.” Google DeepMind’s announcement is the primary source for the rollout and product details.
Why are cyber defenders getting it first?
Google presents Argon as a model that can autonomously find, validate, and patch critical software vulnerabilities. Giving selected defenders access first lets them use those capabilities in defensive work while Google continues evaluating safeguards. The approach reflects the technology’s dual-use nature: a model capable of helping locate weaknesses could also create risks if misused.
#1 Best Overall
For this initial cohort and its internal teams, Google says it is releasing Argon without cyber guardrails so they can use its defensive capabilities. That qualification applies to the restricted first phase; it is not a statement that the model is unrestricted for later customers or the public.
TechRepublic reported on October 2, 2026, that Google model product lead Tulsee Doshi told CNBC that starting with defenders gives Google greater confidence in the rollout while making defensive capabilities available sooner. TechRepublic’s report paraphrases her remarks rather than providing a verbatim quote.
What does Google say Argon can do?
Google describes Argon as a frontier model for complex software engineering, enterprise knowledge work such as legal and finance, and cybersecurity defense. It says the model can handle long-horizon tasks and reports the following evaluation results and examples. These are Google-published claims, not independent confirmation of real-world performance.
| Google-reported result | What Google says it represents |
|---|---|
| 77.9% on DeepSWE v1.1 | Performance on an evaluation Google describes as measuring real-world, long-horizon software-engineering tasks. |
| 68% on CWE-bench v1 | Google says Argon tied for first on this vulnerability-remediation benchmark. |
| 51.3% on AutomationBench | Google describes this Zapier benchmark as measuring end-to-end execution across core business functions. |
| 91.7% on LVBench | Google’s reported result on a long-video-understanding evaluation. |
Google also says an internal vulnerability benchmark covered complex codebases in 20 programming languages, and that Argon outperformed Gemini 3.8 Flash Cyber on Wiz’s internal black-box penetration-testing benchmark. The announcement does not give scores for those comparisons.

Internal engineering examples
- Google says Argon-assisted optimizations freed more than 300 TiB of memory after rollout, with estimated total savings of 500 TiB to 1 PiB.
- For work on its libgav1 video decoder, Google reports Argon’s result was 2.7 times faster than an existing Rust port, with identical video output. This is a specific project example, not a general software-development speed claim.
- Google reports a 40% improvement over a published baseline in an example involving quantum subroutine resource optimization.
Google says Argon supports up to one million output tokens, compared with 64,000 previously. That is the output limit Google reports; it does not by itself establish how a particular task will perform.
What safeguards is Google still working on?
Google says it is iterating on safeguards before broader access and identifies four areas:
- Preventing cyber and chemical, biological, radiological, and nuclear (CBRN) misuse.
- Improving resistance to indirect prompt injection.
- Monitoring model reasoning and actions for signs of misalignment.
- Hardening sandbox environments used for high-risk training and evaluations.
Google says internal and external red teams tested safeguards with manual and automated attacks, but the announcement does not publish full test results. The company says it will continue refining the safeguards using early-user feedback.

When will paid customers and the public get access?
Google’s stated next phase is paid API customers and Google AI Ultra subscribers, after more safeguard work. It then describes expansion toward developers, enterprises, and consumers. No date is given for the next phase or general availability, and the announcement does not spell out the full terms for future subscription access. TechRepublic’s October 2, 2026 report likewise gives no general-release date.
Best Value
Google lists planned API pricing of $2 per million input tokens and $12 per million output tokens at introductory rates, followed by $4 per million input tokens and $18 per million output tokens. The announcement does not state how long the introductory period lasts. These prices describe planned API availability; they do not mean the API is publicly accessible now.
What do the benchmark scores establish?
The scores show what Google says Argon achieved on named evaluations, while the internal examples illustrate tasks Google says its teams completed with the model. They do not, on their own, establish independent verification, broad superiority over other models, or outcomes for a reader’s particular codebase or workflow. The published announcement does not provide enough detail to independently reproduce the results or assess every test condition.
For organizations watching the rollout, the practical unknowns remain eligibility, permitted use, the timing and terms of each access route, and how safeguards will work once access expands.
