Google DeepMind released Gemini 4 Carbon on November 10, 2026, making its strongest frontier model available to developers, enterprises, scientists, and consumers.
Model Capabilities and Performance
Google DeepMind announced that Gemini 4 Carbon is its strongest model to date, built for tasks that test the limits of a model's intelligence such as multi-step coding, debugging, and open-ended scientific research. According to the company, Carbon ranks first on CursorBench 4.0, Perplexity's WANDR, and Zapier's AutomationBench while offering lower cost per task compared to competing external models.
The model is designed to use more tokens than Gemini 4 Argon to explore thoroughly, reason deeply, and run extended verification loops. It also introduces support for a new /swarm preview in Google Antigravity, which turns a single prompt into a coordinated team of agents.
Pricing and Availability
Google DeepMind stated that Gemini 4 Carbon is available via the API in Google AI Studio and Gemini for business for paying developers and enterprises. The model matches the introductory price of Gemini 4 Argon, costing $2 per million input tokens and $10 per million output tokens.
The model is also rolling out to Google AI Ultra subscribers in Google Antigravity, the Gemini app, and AI Mode in Search. Additionally, the company is expanding access to Carbon for scientific researchers through the Google Antigravity usage tier.
Cybersecurity and Safety Features
According to Google DeepMind, Gemini 4 Carbon delivers the company's strongest cybersecurity capabilities to date, leading on benchmarks for finding, exploiting, and patching vulnerabilities when accessed through the Fairwind Program. Early testers used the model to assess vulnerabilities and uncover 0-day bugs.
The company reported that safety mitigations have been strengthened to ensure defensive reasoning does not translate into offensive risk, noting that Carbon blocked 99 percent of attack trajectories during simulated cyberattack testing.
