Google releases Gemini 4 Carbon with agent ‘swarm’ feature

Google has released Gemini 4 Carbon, its strongest AI model yet, capable of competing with Anthropic and OpenAI's systems. It builds on the previous model, Argon, and is designed for tasks that test the limits of a model's intelligence, such as complex coding and scientific research. The model is available to paying developers and enterprises via the Gemini API, and is also available to Google AI Ultra subscribers. A 'swarm' feature on the Antigravity platform allows users to turn a single prompt into a coordinated team of agents.
