Google announced the rollout of Gemini 4 Carbon on Tuesday. Following its release last month, the Mountain View-based tech giant is expanding access to developers and enterprises through paid plans. Meanwhile, Google AI Ultra subscribers can also use it across select products, including the Gemini app and AI Mode in Search. Compared to Gemini 4 Argon, Carbon is claimed to be capable of handling more demanding, multi-step tasks by spending more time reasoning and verifying its output.

Gemini 4 Carbon Features, Availability and Pricing

In a blog post, Google said that Gemini 4 Carbon is its most capable model so far for cybersecurity and long-running agentic workflows. It is said to be designed for complex knowledge work, software engineering, and scientific reasoning, where tasks may require multiple steps, deeper analysis, and repeated verification.

The company claims that Carbon ranks first on three independent benchmarks — CursorBench 4.0, Perplexity's WANDR, and Zapier's AutomationBench. Further, it is also said to achieve more than twice the cost efficiency per task compared to the next-best external model on these benchmarks.

This is Google’s New Frontier AI Model With Cybersecurity Capabilities

For developers working on larger projects, Google is previewing a new /swarm feature in Google Antigravity. It lets users turn a single prompt into a coordinated team of AI agents that can be monitored in real time. Developers can assign Gemini 4 Carbon to tasks requiring deeper reasoning, such as architectural design, coordination, and auditing, while using faster models for parallel tasks across isolated workspaces.

Cybersecurity is one of the key features of Gemini 4 Carbon. The company is offering Gemini 4 Carbon for cyber through its Fairwind Program. Google says the model can inspect software, identify vulnerabilities, trace how flaws could be chained across systems, and generate verified patches.

Gemini 4 Carbon is available through the Gemini API in Google AI Studio and Gemini for Business for paying developers and enterprises. Google has introduced it at the same price as Gemini 4 Argon: $2 (roughly Rs. 187) per million input tokens and $10 (roughly Rs. 936) per million output tokens.

The model is also rolling out to Google AI Ultra subscribers through Google Antigravity, the Gemini app, and AI Mode in Search. Developers can access it through the paid Gemini API tier in AI Studio and Android Studio. Meanwhile, enterprise users can use it via Gemini for business, Google Antigravity, and CodeMender.
