According to a post on X by @theo, Gemini 4 Carbon is "unacceptably slow" in practice. The post times one task at 22m21s on Carbon low versus 9m33s on Claude Opus 5.5 high. It also argues that Claude Opus 5.5 xhigh is cheaper per real-world task than any Carbon effort level, disputing claims that Carbon is the most cost-efficient flagship. @martin_casado takes the other side, but the snippet cuts off before his full argument.

@theo calls Carbon "unacceptably slow" in practice, timing a task at 22m21s on Carbon low versus 9m33s on Claude Opus 5.5 high, and argues Opus 5.5 xhigh is cheaper per real-world task than any Carbon effort level, disputing claims that Carbon is the most cost-efficient flagship. On the other side, @martin_casado...
Teams choosing between models need to weigh speed, effort level and cost per task, not just headline claims. These are single-task timings from one post, so they do not show how Carbon performs across a wider range of work. Watch for more side-by-side timing and cost data from other developers, and for the full reasoning behind Casado's view.
Check the actual price, availability, and account limits before assuming the change applies to you.
