How this studio is built

Keeping the studio cheap to run

Usage

Every message resends a session's whole history, so size is cost. Three changes made on one morning cut the rate to about a fifth for the same work — and a later measurement from the transcripts showed the real figure was better still.

How it runs

  1. Measure from the transcripts
  2. Convert to a share of the budget
  3. Change the expensive thing
  4. Record the evidence

The pieces

Clear at task end
History is the bill; finish, save your place, start fresh.
Low effort by default
Raised deliberately, not as a habit.
A daily share of the budget
The limit is a weekly quota, not hours in a day.
Measure round trips, not words
Terseness saves almost nothing; a stop-and-restart costs a whole re-read.
