Google releases Gemini 4 Carbon AI model to the public with agent swarm feature
Google says Carbon is its strongest model yet and is priced well below rival OpenAI and Anthropic models per token.
Google is rolling out its Gemini 4 Carbon AI model to the general public after first giving it to a select group of cybersecurity defenders two weeks earlier. The company calls Carbon its strongest model and says it can compete with the best systems from Anthropic and OpenAI.
Carbon is available to paying developers and enterprises through the Gemini API, Google AI Studio and Gemini for business, and to Google AI Ultra subscribers in the Gemini app, AI Mode in Search and Antigravity. Google also previewed a "swarm" feature on its Antigravity platform that turns a single prompt into a coordinated team of AI agents. It is unclear whether lower-tier or free users will get access.
Carbon launches at an introductory price of $2 per million input tokens and $10 per million output tokens. Google says that is about a fifth the cost of OpenAI's GPT-6 Astra and a quarter the cost of Anthropic's Fable 5.2. Prices double at the end of November when the introductory period ends. Google's own benchmarks place Carbon among the most powerful models, behind Fable 5.2, though companies can select favorable results.
