Google's new AI model, Gemini 4 Argon, is restricted to cybersecurity experts and the US government in a phased rollout. The model detected a flaw in hospital software and is built for law, finance, and engineering tasks. It includes safeguards blocking cyberattack assistance and weapons development.
