Did you explicitly tell it to use Sonnet or Opus subagents and stick at or below high effort? Asking because such practices make a huge difference in the quality of output and the amount of tokens burned. I used one of my accounts to explore ultramax and it was just a token hog that might be worse than Opus.

I had it on whatever the recommended settings was, but maybe I should have told it to use Sonnet for most subtasks.

Even so, I'm just not that impressed, I felt like I got more done by just using Opus.
