Overview
- Google expanded access on November 10 to paying developers, enterprises and Google AI Ultra subscribers through the Gemini API, AI Studio, Antigravity, the Gemini app and AI Mode in Search.
- Gemini 4 Carbon builds on Gemini 4 Argon by using extra internal 'thinking' tokens to run deeper multi‑step reasoning and verification, which raises per‑task token use because thinking is billed at output rates.
- Google previewed a /swarm multi‑agent feature in Antigravity that coordinates specialized agents from a single prompt so teams can split planning, building, testing and verification across parallel workers.
- DeepMind published AlphaProof Code artifacts that used Carbon to generate Lean proofs verifying key properties of libsignal, and security partners reported fast findings such as Wiz locating zero‑days in under two hours.
- Google cites strong benchmark and internal safety results but independent validation of real‑world performance, task cost when Carbon’s heavier token use is counted, and robustness to sophisticated attacks remains limited.
