Is this new? I remember something in the UI saying Auto mode uses x% more tokens

Yes, it's in the article:

> The auto mode classifier uses a small number of extra tokens per tool call, and we're no longer charging Claude Code users on Pro, Max, and Team plans for that classifier overhead, effective today

That's a bit difference that Boris's claim that they don't charge for this as a "principle".

This just sounds like they bump their unspecified limits by N% to cover this usage. Which of course means nothing because the next time they re-evaluate their limits they will just ignore this bump.

That’s good to know, thank you.
