Google launches Gemini 4 Carbon and previews an agent “swarm” feature
🎧 Listen to this story
Google DeepMind announced Gemini 4 Carbon’s availability two weeks after offering it to cybersecurity defenders through the Fairwind Program. The company says the model is its strongest yet and is designed for complex coding, open-ended scientific research, and long-horizon agentic workflows. Carbon is available through the API in Google AI Studio and Gemini for business for paying developers and enterprises, and to Google AI Ultra subscribers in Antigravity, the Gemini app, and AI Mode in Search. Access for lower tiers and free users was not indicated.
Google also previewed “swarm” in Antigravity, which turns a prompt into a coordinated team of agents. Introductory pricing is $2 per million input tokens and $10 per million output tokens. According to Xataka, Anthropic’s Fable 5.2 outperformed Carbon in several comparisons, although Google’s model led in some tests.
Why it matters · editorial interpretation
The launch combines a new model aimed, according to Google DeepMind, at complex coding and long-horizon agentic workflows with paid API access and a preview of coordinated agent teams. The comparison cited by Xataka suggests performance still varies by test, which matters for those evaluating adoption.
