What is it?
Gemini 4 Carbon is now broadly available, as of 10 November 2026. Paying developers and enterprises get it in Google AI Studio and Gemini for business, and Google AI Ultra subscribers get it in Google Antigravity, the Gemini app and AI Mode in Search. Cyber defenders keep their access through the Fairwind Program.
How does it work?
Google reports that Carbon ranks #1 on CursorBench 4.0, Perplexity's WANDR and Zapier's AutomationBench, at more than 2x lower cost per task than the next-best external model. It also ranks #2 on the Artificial Analysis Multimodal Knowledge Agent benchmark. In simulated attacks, the per-attempt breach rate fell to 0.8% from 3.1% for Gemini 4 Argon.
Why does it matter?
Until now only security teams could use Carbon. The public price matches Argon's introductory rate, so developers can compare the two directly before the price rises on 30 November. Antigravity also adds a /swarm multi-agent feature in preview.
Who is it for?
developers, enterprises, Ultra subscribers, scientists
