They said in the announcement that these high usage limits are only while it's in the preview stage, so they may (or may not) be reduced later. I think (it's not clear, at least to me) that the CLI may be using cheaper models already, at times. It says if you want the freedom to choose your model for every request, you can buy one of the paid subscriptions. I interpret that to mean that some of your requests may go to Gemini 2.5 Pro, but not all of them, and it decides. Am I extremely wrong about that?
