Google Launches Gemini 4 Carbon, Surpassing GPT-6 in Security and Long Context
Google has released Gemini 4 Carbon, a new frontier model that excels in cybersecurity benchmarks with an 88.2% vulnerability detection rate. It demonstrates capability to handle multi-day engineering tasks on large codebases and significantly outperforms competitors in long-context reasoning. Access is currently limited to select cyber defenders via the Fairwind Program, with introductory pricing at $2/$10 per million tokens.

Gemini 4 Carbon, Google's new frontier model, beats GPT-6 Astra and Claude Opus 5.5 on Artificial Analysis.
Arriving 2 weeks after Gemini 4 Argon, Carbon gains most in security: 88.2% on SEC-bench Pro for finding vulnerabilities and 71.0% on CWE-bench for patching. 54.8% on ExploitGym for exploiting them and 71.0% on CWE-bench for patching them.
Because of that exploit skill, access starts this week with a subset of cyber defenders, then trusted partners through the Fairwind Program, before developers, businesses and consumers get it.
Google says Carbon can work on engineering problems for days, root-causing subtle bugs across large codebases instead of stalling at dead ends.
Cost: introductory 10 per 1M input/output tokens, later doubling to $4 and $20.
On long-context benchmark: on GraphWalks (256K to 1M tokens, BFS F1), Carbon scores 96.2%, against Argon’s 84.2%, GPT-6 Astra’s 71.8% and Claude Opus 5.5’s 66.8%.

It’s state-of-the-art across cybersecurity and long-horizon capabilities.
