Thats not even enough to read a simple codebase, how is that enough?

Almost certainly an homage to “640kB ought to be enough for anybody.”

That is a good point actually (this is how we at Hugston measure tokens, in bytes). 270k tokens should be around ~1100kb or 1 MB, so not really enough for a serious project.
