Google has launched Gemini 4 Argon globally for developers and enterprises through its API in AI Studio and Gemini platform. The model is also available to Google AI Ultra subscribers in Google Antigravity, and to Google AI Ultra and Pro subscribers in the Gemini app and AI Mode in Search.
Introductory API pricing is $2 per million input tokens and $10 per million output tokens. Google says cached input tokens cost 95% less. The company describes Argon as a model for complex, multi-step work across coding, finance, legal work, cybersecurity and science. It says the model ranks first on the Vals Index, a benchmark covering work in sectors including finance, coding, legal and tax.
Google reports gains in engineering work
Google says teams using Argon in Antigravity increased agentic code submissions by more than 35% and reduced code rollbacks by nearly a third. For its open-source Agent Development Kit for Python, the company says Argon found optimizations that are now live and cut in-memory session preparation time by 40% in long sessions. Cold imports became 21% faster.
The company also says Argon helped the Chrome team refactor browser feature code across hundreds of files. Google expects that work to let live webpages move between tabs, side panels and floating windows without reloading. It presents that browser capability as a future result of the refactor.
Researchers and security teams use Argon
Google cites early work in cybersecurity and science. It says Wiz used Argon to help find and fix security gaps affecting government and healthcare systems. At Gamow Labs, researchers used the model to identify a chromosomal rearrangement in a de-identified newborn genome that routine software had missed, according to Google.
In other research examples, Google says Argon helped its researchers improve the throughput of a quantum error correction decoder and helped design five new enzymes that showed catalytic activity in laboratory tests. These are examples of specific work reported by the company, rather than results promised for every use of the model.
Google is also offering 10,000 scientists the highest usage tier in Antigravity free for six months, subject to eligibility, capacity and selection. Applications are open, and Google says it will onboard selected scientists on a rolling basis.
