Google rolls out Gemini 4 Argon broadly with new cyber and misalignment safeguards

Google is beginning to roll out Gemini 4 Argon broadly and expanding its Fairwind Program to more trusted cyber defenders.

The company says Argon solved all 12 simulated end-to-end cyberattack scenarios, up from five in the previous generation, and cut prompt injection attack success to 0.7% on Gray Swan's benchmark.

Google describes three layers of real-time protection and an automated monitor that reads the agent's actions and chain of thought.
