How does this not use up tokens incredibly fast though? I have a Pro subscription and bang up against the limits pretty regularly.
I don't know, all I can say is with API-based billing, doing multi-thousand like refactors that would take days to do costs like $4. In terms of value : effort, it's incredible.
It does use tokens faster, yes.
It _does_ use up tokens incredibly fast, which is probably why Anthropic is developing this feature. This is mostly for corporations using the API, not individuals on a plan.
