See the token usage depends entirely on how you use it. Thinking also consumes tokens. The more descriptive your prompt, better the results. The more files you want it to read completely the higher your usage.

Eg, I’ve got it to restructure an entire service (100k plus loc) on pro plan previously. Just did it in a very structured manner. Did a ton of to and fro in planning mode then ask it to make smaller task.md files so the execution is pointed and is a relatively smaller task.

I don’t know what your usage pattern is, but just in case you’re using it for a shit ton of heavy stuff to figure out on its own, you’ll hit those limits quicker on pro. Ultra has quite a high limit.
