Gemini 4 Carbon: our next frontier model · 2026-10-28
Google’s October 28 announcement presents Carbon as a staged-release model for long-horizon engineering and cybersecurity. It separates vulnerability discovery, exploitation and patching evaluations, and describes monitoring, injection defenses and training against shortcut behavior. The reported benchmark and internal-alert improvements are provider measurements; evaluated attacks without successful injection do not establish universal resistance. Initial access is limited to selected defenders and partners, rather than general availability.
