Google rolls out Gemini 4 Argon to selected cyber defenders

Google is rolling out Gemini 4 Argon to selected cyber defenders through its Fairwind Program. The company says the model can autonomously find, validate and patch critical software vulnerabilities, and that trusted defenders will receive access without cyber guardrails. Argon expands the output limit to 1M tokens from 64K tokens for longer workflows. Wiz is already using it through its Scan for Good initiative. Google plans broader access starting with paid API customers and Google AI Ultra subscribers, after further safeguards work.
