Gemini 4 Argon enters a restricted cyber-defence rollout before wider access
Google has announced Gemini 4 Argon, a frontier model aimed at long-horizon coding, professional knowledge work and cyber defence. Its 30 September release begins with selected security defenders, not general public access. Google claims a one-million-token output limit and has disclosed introductory API pricing, while saying broader availability depends on feedback and stronger safeguards.
