Gemini 4 Carbon focuses on cybersecurity and long-running agent tasks. Access begins with selected defenders, while broader developer and consumer availability is planned for later.
AT A GLANCE
Key points
- Initial access is limited to selected cyber defenders.
- The model targets long-running coding and security tasks.
- Introductory pricing is $2 for input and $10 for output per million tokens.
- Broader developer and consumer access is planned for later.
What is changing?
Google announced Gemini 4 Carbon on October 28. The new frontier model is designed for cyber defense and long-horizon engineering tasks that can run for days. Access starts this week with a subset of cyber defenders and will gradually expand to trusted partners through the Fairwind Program; general availability for developers, businesses and consumers has not started.
In Google’s reported evaluations, Carbon scored 88.2% on SEC-bench Pro, 54.8% on ExploitGym and 71.0% on CWE-bench. The company also says the model produces fewer unsupported claims and follows through more reliably on long coding tasks. These provider-reported results still need validation on production data.
During the introductory period, pricing will be $2 per million input tokens and $10 per million output tokens, with cached input priced at a 95% discount. Google plans to raise those prices to $4 and $20 after the introductory period. Access will expand as safety evaluations continue.
