With ULTRATHINK

ULTRATHINK What's wrong with my growth strategy?

What changes in Claude's response

Where L99 commits to an opinion, ULTRATHINK commits to a thesis. You get a 6-8 paragraph response that covers the surface answer, then digs through 3-4 layers underneath, then names the structural cause, then tells you what to do about it. The response feels like a senior consultant who's been thinking about your problem for an hour, not 10 seconds.
