Google is giving Gemini 4 Argon to government and cyber defenders first

Google is launching Gemini 4 Argon with government users and trusted cyber defenders first, rather than opening the model to everyone. The rollout runs through the Fairwind Program, where early users will help test its guardrails before broader access.

Argon is built for complex workflows, software engineering, enterprise knowledge work, and cybersecurity defense. Google says teams are already using it for coding and quantum-computing work, while the model supports up to 1 million output tokens versus 64,000 for its predecessor. Paid API and Google AI Ultra access is planned after testing.
