Google releases Gemini 4 Carbon with agent ‘swarm’ feature

Google released Gemini 4 Carbon to paid developers, enterprises and Google AI Ultra subscribers, aimed at complex multi-step coding and open-ended scientific research. Google also previewed a swarm feature in Antigravity that turns a single prompt into a team of agents working together.

Why it matters: Google set Gemini 4 Carbon's token pricing below frontier competitors, though total task cost still depends on how many tokens the model consumes.
