Google releases Gemini 4 Carbon with agent ‘swarm’ feature

Google is rolling out its latest AI model, Gemini 4 Carbon, to the general public after releasing it to a select group of “cybersecurity defenders” two weeks ago. Google claims Carbon is its “strongest model” yet, and capable of competing with the very best systems from Anthropic and OpenAI.

Google says Gemini 4 Carbon “pushes the frontier even further” than Argon, referring to the company’s other frontier model that launched only last month. The company said Argon will likely remain “the ideal choice for the majority of software engineering and knowledge work,” but that Carbon is “built for tasks that test the limits of a model’s intelligence,” such as complex, multi-step coding and open-ended scientific research.
