Google releases Gemini 4 Carbon

Original title: Gemini 4 Carbon is now available

Plain language

What it is: Google has released Gemini 4 Carbon, a new artificial intelligence model. It is designed for complex tasks in cybersecurity, software engineering, and scientific research.
How it works: The model uses more data tokens than previous models to reason deeply and run verification loops. It can also coordinate teams of AI agents to work together on large projects.
Where it is available: It is available through the API in Google AI Studio, Gemini for business, the Gemini app, Google Antigravity, and AI Mode in Search.
Example: A team of these AI agents used planning documents to build an interactive 3D reconstruction of an office building.

What it is: Google DeepMind has launched Gemini 4 Carbon, a model optimized for cybersecurity, long-horizon agentic workflows, and complex coding.
How it works: It utilizes more tokens than Gemini 4 Argon to perform deep reasoning and extended verification loops. Developers can also use the new /swarm feature in Google Antigravity to deploy Carbon in coordination and auditing roles alongside lighter models.
Where it is available: It is accessible via the API in Google AI Studio and Gemini for business for paying users, and is rolling out to Google AI Ultra subscribers in Google Antigravity, the Gemini app, and Search.
Example: Researchers used Carbon within an agentic framework to generate millions of lines of Lean code, mathematically proving the security properties of Signal's cryptographic protocol.
