Google opens Gemini 4 Carbon to paying developers and Ultra users
2026-11-10 · New
Google expanded Carbon beyond its earlier specialist program to paid APIs, enterprises and Google AI Ultra users. Public-model API input/output pricing is temporarily $2/$10 per million tokens, rising to $4/$20 after the introductory period ends November 30. Developers can use AI Studio and Android Studio access paths; the Fairwind cyber-defense program still requires an application. Antigravity’s accompanying /swarm multi-agent feature remains a preview, distinct from model availability.
