Gemini 4 Argon, Google's new frontier model
Gemini 4 Argon is Google's new frontier model
Google has announced Gemini 4 Argon, its new frontier model. It is rolling out first to trusted cyber defenders, through Google's Fairwind Program.
Built for long, multi-step work
Gemini 4 ArgonArgon is built for long, multi-step work
Google built it to keep reasoning through long, complex work. That means real-world software engineering, enterprise knowledge work like legal and finance, and cybersecurity defense.
Output limit rises to 1M tokens
Gemini 4 ArgonOne answer can now run to 1M output tokens
Up from 64K tokens before.
For builders, one response can now run to a million output tokens. The previous limit was 64,000. Google says the headroom lets it solve a hard problem in one pass.

Top score on long software tasks
Gemini 4 ArgonGoogle reports a new best score on long, real-world coding tasks
Google's own table puts it behind rivals on Terminal-bench and FrontierSWE.
Google reports Argon sets a new state of the art on DeepSWE, a test of long, real-world software tasks. Google's own results table also shows rivals ahead on Terminal-bench and FrontierSWE.
A video decoder rewritten in safe Rust
Gemini 4 ArgonArgon agents made Google's Rust video decoder 2.7× faster
libgav1: 32K lines of SIMD code replaced with safe Rust, identical video output.
Inside Google, Argon agents rewrote the libgav1 video decoder's Rust port. They replaced about 32,000 lines of SIMD code with safe Rust. Google says it now runs 2.7 times faster, with identical output.
Leading on finance, legal and tax work
Gemini 4 ArgonGoogle reports Argon leads on finance, legal and tax work
Vals Index: tasks weighted by each sector's share of U.S. GDP.
Beyond code, Google reports Argon leads the Vals Index. It mixes finance, coding, legal and tax work, each weighted by its share of the U.S. economy. Google also reports first place on Zapier's business automation test.
Charts, documents and long videos
Gemini 4 ArgonIt reads charts, document sets and long videos
Google reports a new best score for long-video understanding.
Argon also works with images and video. Google says it can analyze charts, pick details out of long videos, and act on a set of documents. Google reports a new best score on long-video understanding.
Finds, validates and patches vulnerabilities
Gemini 4 ArgonArgon can find, validate and patch software vulnerabilities
Trusted defenders get it without cyber guardrails.
Google trained Argon for cyber defense. It can find, validate and patch critical vulnerabilities on its own. Trusted defenders and Google's own teams get it without cyber guardrails.
Wiz found a hospital software flaw with it
Gemini 4 ArgonWiz used Argon to find a critical flaw in hospital software
Earlier frontier models had missed it.
The security company Wiz uses it in Scan for Good, its free program protecting public infrastructure. Google says Argon found a critical flaw in hospital software worldwide that earlier frontier models had missed.
Who gets it
Gemini 4 ArgonWho gets it, and what it costs.
Fairwind partners only, for now
Gemini 4 ArgonToday, only approved Fairwind partners can use Argon
Right now, only approved Fairwind partners get Argon. They may give it only to internal security, incident response and penetration testing teams. On Gemini Enterprise, it supports zero data retention.
Paid API customers and Ultra subscribers next
Gemini 4 ArgonPaid API customers and Google AI Ultra subscribers come next
Then developers, enterprises and consumers, "as soon as possible".
Google is widening access gradually while it tests guardrails. Paid Gemini API customers and Google AI Ultra subscribers come next. Google gives no date, only "as soon as possible".
$2 in, $10 out, at an introductory price
Gemini 4 ArgonIntroductory price: $2 in, $10 out per million tokens
The introductory price is 2 dollars per million input tokens and 10 dollars per million output tokens. Cached input is 95 percent off. Afterwards, it doubles to 4 and 20 dollars.
Not in the Gemini API yet
Gemini 4 ArgonArgon has no Gemini API model ID yet
Announcement: blog.google › Gemini 4 Argon · Watch: ai.google.dev › Gemini models
For developers today, Argon is missing from the Gemini API models page, with no model ID to call. Watch that page for it. That's Gemini 4 Argon, Google's new frontier model.
