Google has expanded access to Gemini 4 Carbon less than two weeks after introducing the model on October 28. According to InfoQ, it is now available through Google AI Studio, Gemini for business and Google Antigravity, as well as the Gemini app and Search AI Mode for Google AI Ultra subscribers. Its more capable cybersecurity version remains subject to controlled access through Google’s Fairwind Program.
Google is positioning Carbon for difficult, long-running work rather than routine tasks. It says the model ranked first in three agent-workflow evaluations—CursorBench 4.0, Perplexity WANDR and Zapier AutomationBench—and that its cost per completed task was less than half that of the next-best external model in those tests. These are Google-reported results, not evidence that Carbon leads on every task. InfoQ notes that Claude Fable 5.2 scored higher in the Artificial Analysis Intelligence Index configuration it cited and in the FrontierSWE v2 software-engineering evaluation.
For developers, Google has introduced a /swarm preview in Antigravity. It lets a user assign work to multiple agents, monitor their progress and have them operate in separate workspaces. Google’s demonstrations include interactive 3D reconstructions built from historical images and engineering documents; they do not establish that the system can deliver production software without human oversight.
Google also reported cybersecurity results, including 100% recall at the scanning stage of an internal Project Fortify benchmark and 95% precision in vulnerability triage. Those figures describe that benchmark, not a general guarantee of vulnerability detection. Google said it helped validate two exploitable flaws in an unnamed open-source product, but withheld details while coordinating disclosure and patching.
Carbon’s public API has a temporary price of $2 per million input tokens and $10 per million output tokens. Google says the offer ends November 30, 2026; standard prices will then be $4 and $20, respectively. A lower token price does not necessarily mean a lower total cost for every task: Google says Carbon can use more tokens than Gemini 4 Argon on complex work.
