Google unveils Gemini 4 Carbon AI model, withholds public access
Google has announced Gemini 4 Carbon, a frontier AI model released just two weeks after Gemini 4 Argon, which it says improves on coding, agentic tasks, scientific analysis and cybersecurity. The company reports gains such as doubled vulnerability-free code generation versus Argon and a 10x improvement in patch quality claimed by its Chrome team, plus an 89-point jump on the WebDev Arena leaderboard. Despite announcing the model, Google is not yet making it broadly available, instead pursuing a staged rollout.
