Google unveils Gemini 4 Argon, a frontier model for long-horizon coding, legal, finance and cyber work, rolling out to vetted defenders first.
Google DeepMind announced Gemini 4 Argon, a new frontier model with a 1 million token context window built for deep reasoning across complex, long-horizon professional workflows.
Google says it delivers frontier performance in real-world software engineering, enterprise knowledge work such as legal and finance, and cybersecurity defense including autonomous vulnerability patching.
Argon is initially rolling out to trusted cyber defenders through the Fairwind Program, with Google taking a phased approach and safety testing before broader release.
