Google Launches Gemini 4 Argon for Cyber Defenders as Frontier Model Race Tightens

Google DeepMind has introduced Gemini 4 Argon, a frontier AI model for long-running coding, knowledge-work and cybersecurity-defense tasks, beginning with a limited rollout to trusted cyber defenders. The launch puts Google back into direct comparison with OpenAI's GPT-6.1 Sol and Anthropic's Claude Opus 5.5, with aggressive introductory pricing, a 1 million-token output ceiling and early debate over how benchmark strength will translate into production work.
