Overview
- Google rolled out Gemini 4 Carbon to paying developers, enterprises, and AI Ultra subscribers on Tuesday, November 10, and made it available across the Gemini API in AI Studio, the Gemini app, AI Mode in Search, Gemini for business, and Antigravity.
- Google positions Carbon as a 'frontier' model for complex, multi‑step reasoning, coding, and research while keeping Gemini 4 Argon as the recommended option for routine engineering and knowledge work.
- Antigravity will preview a coordinated agent 'swarm' feature that turns a single prompt into a tracked team of agents that can split roles such as design, verification, and auditing for long‑horizon workflows.
- Carbon launches with introductory pricing of $2 per 1M input tokens and $10 per 1M output tokens through November 30 and will double after that, but Google’s token‑use differences and limited independent testing leave real task costs uncertain.
- Google released a new Multimodal Knowledge Agents (MKA) benchmark with partner Artificial Analysis that ranks Carbon highly on 200 agentic tasks, yet access remains staged after early provisioning to vetted cyber defenders and capacity limits exposed during the Argon rollout.
