At least Anthropic tells you how many more tokens you’re paying for! 5x 10x 20x whatever. Google seems to just say more, higher, highest.
The pricing page for Claude literally says "More usage" for the $17/month pro plan. Doesn't really quantify anything. The usage is whatever they feel like it should be.
And then the very expensive plan says "Choose 5x or 20x more usage than Pro". It's all arbitrary.
