Gemini 4 Carbon Launches for Developers

Google released its Gemini 4 Carbon model on November 10, 2026, making it available to developers and AI Ultra subscribers. The model features an introductory price of $2 per million input tokens and $10 per million output tokens, which doubles after November 30, 2026.

This release positions Carbon as Google's most powerful AI model, emphasizing its capabilities in cybersecurity and complex reasoning. It aims to streamline multi-step problems across various fields, including software engineering and scientific research. The move places Google in direct competition with leading AI models from OpenAI and Anthropic.

Gemini 4 Carbon Targets Agentic Workflows and Cybersecurity

The model's cybersecurity strengths could include sophisticated threat detection and automated vulnerability analysis. This emphasis comes as AI-powered attacks increasingly challenge traditional defenses. Developers can use Carbon for secure code generation and adaptive defense systems.

Google highlights Carbon's robust performance in agentic workflows, a key area for advanced AI applications. This allows the model to handle complex tasks that require multiple steps and sustained interaction. For more on Google's AI agent initiatives, see our article on Gemini's agentic capabilities.

How Does Pricing and Access Work?

The introductory pricing for Gemini 4 Carbon is $2 per million input tokens and $10 per million output tokens until November 30, 2026. After this date, the price doubles to $4 per million input tokens and $20 per million output tokens.

This pricing structure places it competitively against other models. For comparison, Anthropic charges $8 per million input tokens and $40 per million output tokens for its Claude Fable 5.2 model.
