Google says Gemini 4 Argon can find and patch critical software flaws

Google announced Gemini 4 Argon, a frontier AI model it says can locate, validate, and patch critical software vulnerabilities without human help, and is rolling it out to trusted cyber defenders through its Fairwind Program. Google will release a version of Gemini 4 Argon without cyber guardrails to those defenders and to its own internal teams, with developers, enterprises, and consumers gaining access later starting with paid API customers.
