Google releases Gemini 4 Argon, called its most powerful model yet

Alphabet has launched Gemini 4 Argon, a new AI model it describes as built for tasks including coding, research and writing. Google says the model has a particular aptitude for cybersecurity.

Argon is being rolled out only to a select group of the company's cyber partners through Google's Fairwind Program, its security initiative. Google says the model was trained specifically for defensive cyber work and can "autonomously find, validate, and patch critical software vulnerabilities."

Google also says Argon performs well at coding and engineering, noting that its own staff have used the model for daily work including debugging and codebase migrations. The company additionally touts the model's ability to parse visuals, such as analyzing the contents of long videos or charts.

"Built to sustain deep reasoning across complex, long-horizon workflows, Argon is fundamentally changing the way we work and build at Google," the company said in a blog post Wednesday.

In that blog post, Google claims Argon scored significantly higher than OpenAI's GPT-6 Astra and Anthropic's Fable and Opus models across a variety of AI benchmarks. It cites Vals, a benchmarking startup, to show that Argon is currently the leading model on the company's AI model index.

The release comes amid a wave of model launches from top AI labs, including OpenAI's Astra, which it called its best model yet, and Anthropic's Fable earlier this year.

Google announced in August that its Gemini app had over a billion users per month, a metric it said makes the app competitive with OpenAI, which also recently announced that ChatGPT had reached a billion monthly users.
