Summary

Google unveils Gemini 4 Argon, a cyber-defense model it says can autonomously find, validate and patch critical vulnerabilities, initially restricting access to trusted defenders in its Fairwind Program after Wiz uses it to uncover a healthcare-software flaw earlier frontier models missed.

Key Points

  • Google announces Gemini 4 Argon, a frontier model rolling out first to trusted cyber defenders through its Fairwind Program before broader access.
  • Argon expands its output limit to 1 million tokens from 64,000 and sets a 77.9% state-of-the-art score on the DeepSWE v1.1 software-engineering benchmark.
  • Google says Argon can autonomously find, validate and patch critical vulnerabilities; Wiz uses it to uncover a healthcare-software flaw that previous frontier models missed.
