I rarely use Opus for planning (in the Pro plan). Spec a feature in Sonnet, hand it to Haiku, come back for review. That’s a 5-hour window gone, sometimes 2.

I hit my weekly limit around day 4, with 2 maxed out windows per day (and sometimes a bit of usage at night).

I completely understand why people would use Opus for everything, it’s much more thorough and effective. Sonnet as well, but on Pro it’s gonna be Haiku all the time.
