Does the System Automatically Upgrade to "Thinking" Mode?

I want to know if the system automatically upgrades to the thinking model.

Specifically, I’m curious about:

  • What triggers this automatic upgrade? Is it based solely on the complexity of the problem, or are factors like system load and response speed also taken into account?
  • Will the system automatically switch to the thinking mode when I encounter a particularly challenging programming issue?
  • Is there any way to monitor or adjust this behavior through configuration?
