Google announces Gemini 4 Carbon with a restricted rollout

Availability and evidence

Google announced Carbon on October 28 and said a subset of cybersecurity defenders would begin receiving access that week, with additional trusted partners phased in through Fairwind. The announcement describes Carbon as building on Gemini 4 Argon. This dates the announcement rather than asserting every selected partner received access that day. [1]

Google reported improvements in cybersecurity and sustained engineering work, along with a score of 59 on Artificial Analysis’s updated Intelligence Index. These measurements do not establish broad deployment: access for ordinary developers, businesses and consumers was still forthcoming. [1]
