Google Launches Gemini 4 Carbon and Antigravity Agent Swarms

Google released Gemini 4 Carbon, its most capable AI model to date, designed for demanding, long-running tasks and complex queries. The model integrates into the Gemini app, Google Search AI Mode, and the Antigravity development platform, offering improved reasoning, intent understanding, and instruction following over the Auto and Fast options.

Access is currently restricted to Google AI Ultra subscribers aged 18 and older using personal accounts. For enterprises and developers, the model is available via Gemini for business and the Gemini API in Google AI Studio. Pricing is set at $2 per million input tokens and $10 per million output tokens, though introductory API token rates are scheduled to double after November 30.

Alongside the model launch, Google introduced a preview of Antigravity, a system that transforms a single prompt into a coordinated swarm of AI agents. While the company continues to recommend the Argon model for most software engineering and knowledge work, the Carbon rollout follows a limited release to cybersecurity professionals two weeks prior.
