where do I find the paid option? I can not find that on their product page. There are only two options I can see; one "Available at no charge" and another one "Coming soon - For organizations"

Can you upgrade in the IDE? It would be strange that Google has a performance problem for paid users while I do not experience any such issues at all with Claude and Codex.

Maybe it's unavailable in your region. Four options on this page for me.
