Google DeepMind releases Gemini 4 Carbon frontier model

Google DeepMind has made Gemini 4 Carbon available to developers, enterprises, scientists and consumers. The company describes Carbon as built for work that tests a model's limits — long multi-step coding and debugging, open-ended scientific research — and says it spends more tokens than Gemini 4 Argon, which it positions as the better fit for most software engineering and routine knowledge work. Carbon is offered through the API in Google AI Studio and Gemini for business for paying developers and enterprises at introductory pricing of $2 per million input tokens and $10 per million output tokens, and is rolling out to Google AI Ultra subscribers in Google Antigravity, the Gemini app and AI Mode in Search. DeepMind also previewed /swarm in Antigravity, which coordinates teams of agents from one prompt.
