Google releases Gemini 4 Carbon with agent ‘swarm’ feature

Google has released Gemini 4 Carbon, its most powerful AI model, to paying developers and enterprises after an initial rollout to cybersecurity defenders. Google claims Carbon surpasses its previous frontier model, Argon, and can compete with top systems from Anthropic and OpenAI. Carbon is designed for complex, multi-step coding and open-ended scientific research. Alongside the model, Google is previewing a "swarm" feature on its Antigravity agentic development platform that turns a single prompt into a coordinated team of agents. Carbon is available via the Gemini API, Google AI Studio, Gemini for business, and to Google AI Ultra subscribers in the Gemini app, AI Mode in Search, and Antigravity. It is priced at $2 per million input tokens and $10 per million output tokens, significantly cheaper than rivals like OpenAI's GPT-6 Astra and Anthropic's Fable 5.2, with prices doubling after November.
