/model switches brains: bigger for judgment and the writing that reaches a client or the public, smaller for sorting comps and extracting fields. Extended thinking buys depth on genuinely hard problems (a tricky pricing call) and wastes money on easy ones. Deliberate switching is the difference between a $2 day and a $20 day with identical output.
