Google introduces Gemini 4 Argon with staged cyber rollout

Google says Argon is built to sustain deep reasoning across complex, long-horizon workflows.[1] The company initially rolled it out to trusted cyber defenders through its Fairwind Program, and says it will use early-tester feedback to iterate on guardrails before making the model more broadly available.[1] Google also says it is participating in the U.S. government’s voluntary process for pre-release model access.[1] It plans to make Argon available to developers, enterprises and consumers as soon as possible, but the evidence does not provide a date for that wider release.[1]

Google set introductory pricing at $2 per million input tokens and $10 per million output tokens.[1] Cached input tokens are priced at a 95% discount to the input-token rate.[1] The Verge reported that Argon’s introductory token prices were around one-fifth the prices of OpenAI’s GPT-6 Astra and Anthropic’s Fable 5 models.[3] It also reported that Argon’s prices would double when the introductory period ended at the end of November.[3] The Verge said Argon was rolling out in the Gemini app and Search’s AI mode to Google Pro and Ultra subscribers, and on Antigravity to Ultra subscribers.[3] It said it was unclear whether or when Plus subscribers or free users would get access.[3]

Google describes Argon as delivering frontier performance across software engineering, enterprise knowledge work and cybersecurity defense.[1] Google DeepMind says Argon can generate validated code fixes automatically after finding vulnerabilities, and ties for first on CWE-Bench with a score of 68%.[4][5] Google also calls it its most resilient model against indirect prompt injections.[5] Google says thousands of its employees highlighted strengths in specialized coding, deeper research and writing quality.[1] The Verge reported that Google said Argon outperformed GPT-6 Astra, Claude Fable 5.1 and Claude Opus 5.5 across benchmarks including coding, cybersecurity, science, finance and law.[3] These are company claims and reported benchmark comparisons, not evidence here of results in every organization’s workflows.

Google DeepMind says Argon is expanding to hundreds of additional Fairwind Program partners.[5] Cybersecurity company Wiz used early access to Argon to protect critical healthcare infrastructure and hundreds of thousands of patient records, according to Google.[4] The Verge reported that Google used Argon to halve the computing power needed for YouTube’s comments section and to debug a drone-physics simulator for its delivery company Wing.[3] These examples span security, infrastructure and engineering tasks, but they do not establish that the same outcomes will transfer to other deployments.
