Google DeepMind Launches Gemini 4 Carbon, Its Strongest Model Yet

OFFICIAL Written by GPN · Nov 10, 2026, 5:00 PM ET · · AI

Google DeepMind has released Gemini 4 Carbon, its strongest model to date, built for work that pushes a model's limits: long, multi-step coding and debugging, open-ended scientific research, and complex knowledge work. It is available now through the Gemini API in AI Studio and Gemini for business, and is rolling out to Google AI Ultra subscribers in the Gemini app, Antigravity, and AI Mode in Search.

DeepMind says Carbon ranks first on CursorBench 4.0, Perplexity's WANDR and Zapier's AutomationBench, at more than twice lower cost per task than the next best external model. On a new Multimodal Knowledge Agent benchmark built with Artificial Analysis, it ranks second while costing more than six times less per task than the top model.

The model also carries DeepMind's strongest cybersecurity capabilities. Offered to defenders through the Fairwind Program, it leads benchmarks for finding, exploiting and patching vulnerabilities, and in internal testing it reached full recall on scanning and 95% precision on triage in Project Fortify, Google's autonomous vulnerability system.

Carbon also played a role in the AlphaProof Code project that formally verified the code behind Signal's encryption protocol, work DeepMind says took weeks where expert teams would historically have needed years. It is priced at the same introductory rate as Gemini 4 Argon: $2 per million input tokens and $10 per million output tokens.
