Ive said it before and Ill say it again. These are tools that require skill and training. If you throw an untrained intern at it without prep they'll eat through tokens like crazy, and you wont get much gain.
Theres lots of ways to reduce tokens used by huge amounts, the difference can be on the scale of 90% or better reductions in usage.
But it takes setup, skill, tools, etc. All which require training and learning for the user to know what to use, how to use it, and when.
