Google releases Gemini 4 Carbon for complex agent tasks and scientific reasoning

Gemini 4 Carbon is now available

Google has released Gemini 4 Carbon to developers, enterprises, scientists and consumers, targeting complex knowledge work, agentic coding, cybersecurity and scientific reasoning. Carbon ranks first on CursorBench 4.0, WANDR and AutomationBench, and Google says it costs more than 2x less per task than the next-best external model.

Why it matters: Google sets Carbon at the same entry price as Argon, with Carbon spending more tokens on reasoning and verification for complex multi-step tasks.
