There's a pretty huge range. It's a function of how much you load into context and how long the task is. So if you dump an entire directory with 100k tokens into context and then proceed to do a task that requires 20 steps, that will cost you a lot. Maybe >$10. But a small task where you're just making a few changes and only have a few small files in context (say 5k tokens) won't cost much at all, maybe like $0.10.

I haven't done too much digging into exactly how much people who are using Plandex Cloud are spending, but I'd say the range is quite wide even among people who are using the tool frequently. Some are doing small tasks here and there and not spending much--maybe they're on track for $5-10 per month, while I'd guess some other heavy users are on track to spend hundreds per month.
