Gemini 4 Carbon is rolling out, with an agent ‘swarm’ preview, The Verge reports

Google says Carbon is rolling out to paying developers, enterprises and AI Ultra subscribers. The company is also previewing Antigravity’s ‘swarm’: one prompt, a whole team of agents. Google calls Carbon its strongest model yet, but says Argon will likely remain the ideal choice for most software engineering and knowledge work. Access for free users and lower-tier subscribers remains unclear, The Verge reports.
