Google makes Gemini 4 Carbon generally available, with an agent 'swarm' preview

What happened

Google says Carbon was first released to cybersecurity defenders through its Fairwind Program about two weeks earlier.

API pricing matches Argon's introductory rate: $2 per million input tokens and $10 per million output tokens.

Carbon is available in Google AI Studio and Gemini for business, for paying developers and enterprises. Consumer access in AI Mode and the Gemini app is for Google AI Ultra subscribers.

Google Antigravity added Carbon alongside a new /swarm multi-agent feature, in preview. As the name suggests, /swarm runs several agents together on a task.

Why it matters for creators

Multi-agent features like /swarm point to automated production pipelines where one agent plans shots and others generate assets.

That kind of set-up is still early. /swarm is a preview inside a developer tool, not a finished creative product. But it shows the direction of travel: work split across several coordinated agents rather than handed to a single model.

For creators on Google's consumer plans, Carbon in the Gemini app and AI Mode requires an AI Ultra subscription.
