Gemini 4 Carbon is now available

Google has made Gemini 4 Carbon available to developers, enterprises, scientists, and consumers. This model boasts frontier performance in cybersecurity capabilities and long-horizon agentic workflows across complex tasks, software engineering, and scientific reasoning. Two weeks ago, Google released Carbon to cybersecurity defenders through the Fairwind Program.

Gemini 4 Argon remains an excellent option for most software engineering and knowledge work, while Carbon excels in tasks that require extensive reasoning, such as complex coding and debugging, and open-ended scientific research. Carbon demonstrates superior accuracy against independent benchmarks while being up to 6 times cheaper than the leading model for many tasks.

Google is previewing /swarm, which allows a single prompt to orchestrate a team of agents for larger, complex projects. Developers can assign Carbon to demanding roles, while faster models handle parallel tasks. Gemini 4 Carbon is accessible via Google AI Studio, Gemini for business, and Google Antigravity, with pricing identical to Gemini 4 Argon. The model further strengthens safety and security measures to prevent misuse and prompt injection.
