Google has announced Gemini 4 Argon, its latest frontier AI model designed to handle complex tasks that require deeper reasoning and longer workflows. The new model brings improvements across coding, enterprise work, cybersecurity, research, and multimodal tasks, while also significantly increasing how much content it can generate in a single run.

Argon isn’t immediately available to everyone. Google is initially rolling it out to a group of trusted cybersecurity defenders through its Fairwind Program while it continues testing the model and improving its safeguards. A sensible choice given multiple rogue AI hacks lately. Access will gradually expand to developers, businesses, and consumers, starting with paid API customers and Google AI Ultra subscribers.

What’s new in Google Gemini 4 Argon?

One of the biggest upgrades is the output token limit. Google has increased it from 64,000 tokens to 1 million tokens, allowing Argon to work through significantly longer and more complicated problems without having to stop. The company says this additional room allows the model to sustain deeper reasoning and produce hundreds of thousands of tokens during a single workflow.

Thousands of Google employees are already testing Gemini 4 Argon for coding, research, writing, and other specialized tasks. According to Google, the model has also helped its researchers optimize quantum computing algorithms, including one example where it improved on a published baseline by 40% within minutes.

Google has also deployed Argon agents to analyze memory usage across its data centers. The resulting optimizations have already freed more than 300 TiB of memory, with the company estimating that total savings could eventually reach between 500 TiB and 1 PiB.

Argon agents are also being used to help migrate large C and C++ codebases to Rust, including projects ranging from tens of thousands of lines to more than 800,000 lines. In one example involving Google’s libgav1 video decoder, Argon helped replace 32,000 lines of SIMD code, resulting in a Rust version that Google says runs 2.7x faster than the previous Rust port while producing identical video output.

That said, when wider access begins, Gemini 4 Argon will have an introductory price of $2 per million input tokens and $10 per million output tokens, while cached input tokens will be offered at a 95% discount compared with the standard input price. No exact date
