Google rolls out Gemini 4 Argon, its most advanced AI model

Alphabet unveiled Gemini 4 Argon on Wednesday, its most advanced artificial intelligence model yet, offering major improvements in coding, cybersecurity, and complex professional work.

The company said the model sets a new record in real-world software engineering, ties for first in cybersecurity, and leads another benchmark measuring performance across finance, legal, and other professional tasks.

Argon is already being used internally to optimize memory at Google's data centers, freeing up hundreds of terabytes of memory without buying additional hardware, the company said. Quantum computing researchers have also utilized the model.

Google said it plans to launch the new model in phases, starting with trusted cybersecurity partners, as it works on a pre-release safety evaluation with the U.S. government.

The model release comes a day after CEO Sundar Pichai signed a voluntary safety accord with President Donald Trump following a meeting with major tech executives at the White House to address rising AI safety concerns.

For the last year, Google has focused on scaling faster, lower-cost flash models. Gemini 4 represents a major push at the frontier, nearly a year after Gemini 3 put the tech company back at the forefront of the AI model race.

Google on Wednesday said it's looking to scale safeguards in four key areas, including misuse and prompt injection, before launching publicly.

Google said Argon represents a major step up in cybersecurity capabilities from the 3.8 Flash Cyber model, released earlier this month, and outperforms on vulnerability discovery.

Argon also ties with OpenAI's GPT-6 Astra and Grok 4.7 on cybersecurity evaluation benchmarks and ahead of GPT-6 Astra and Anthropic's Fable 5.1 on the Vals Index.
