Gemini 4 Carbon is Google DeepMind's next frontier model, announced on 2026-10-28, which Google describes as "our strongest model with state-of-the-art cybersecurity and long horizon capabilities." It builds on Gemini 4 Argon, with gains in vulnerability finding, exploit validation, patching, and long-horizon agentic coding. At announcement it is in a limited rollout: available only to a subset of cyber defenders and, in phases, to trusted partners through Google's Fairwind Program, with availability to developers, businesses, and consumers planned later. Google states it will launch at the same introductory price as Argon ($2.00 per million input tokens, $10.00 per million output tokens, cached input 95% off), moving to $4.00/$20.00 after the introductory period. There is no public API endpoint yet.
