Google says its latest AI model leads several benchmarks, but will initially limit access to selected cybersecurity defence companies.
Google has unveiled Gemini 4 Carbon, claiming gains in coding, cybersecurity and other artificial intelligence tasks. The company will initially give selected cybersecurity defence companies access for pre-release testing.
The model follows Gemini 4 Argon, which Google launched two weeks earlier. In a blog post, the company presented Carbon as its latest step in advancing frontier AI capabilities.
Gemini 4 Carbon leads Google’s benchmark results
Google’s benchmark results place Carbon first on the AA Index v5.0, a general AI assessment, with 59 points. That puts it just ahead of competing models Claude Opus 5.5 and GPT-6 Astra.
The company also claims leading results across most tested categories, including agentic coding, computer use and knowledge work. Its results cover science and mathematics as well.
However, Google placed particular emphasis on cybersecurity, where it reported wider margins over rival models. The company says Carbon can identify vulnerabilities, rank their importance and address their underlying causes through patches.
Compared with Argon, Google says the new model is also twice as likely to generate secure code. These performance claims come from the company’s benchmark results.
Restricted access before a wider release
Beyond performance, Google says Carbon improves safety and security by reducing shortcuts and the exploitation of loopholes. It also claims better transparency and honesty, including performance on a test assessing unsupported claims.
The company reports stronger resistance to prompt injection, alongside improved collaboration and task completion without overstepping. It presents these changes as advances in how the model handles instructions and carries out work.
Meanwhile, Google’s release plan starts with selected cybersecurity defence companies conducting pre-release testing. The company then plans to extend access to additional trusted partners through its Fairwind Program before a wider release.
That approach follows the rollout Google used for Argon. The earlier model is now available through the Gemini app and Google’s AI search mode.
