Google Announces Gemini 4 Carbon as Early Tests Highlight 3D Gains and Slower Responses

Google announced Gemini 4 Carbon on Oct. 28, positioning it as a model for long-running engineering work and cybersecurity. Early creative-task comparisons point to stronger 3D output than Gemini 4 Argon, alongside slower responses and weaker interface design. Google plans to begin access this week with selected cyber defenders, then expand through its Fairwind Program while it gathers feedback and refines safeguards. The company has not given a date for broader availability. Google’s announcement describes Carbon as an upgrade built on feedback from Argon.
