Gemini 4 Carbon is here!

Our strongest model is now available, with frontier performance in cybersecurity and long-horizon capabilities. Built for your toughest engineering work, Carbon takes the time to explore thoroughly, reason deeply, and run extended verification loops to tackle your most complex workloads with less prompting and hand-holding.

Alongside Carbon, we’re previewing /swarm in Google @Antigravity so you can spin up a team of agents from one prompt, assigning Carbon to architecture and auditing while parallel agents build and test every change.

Here’s how you can build with Carbon ↓
