What's Wrong or Missing?

The documentation doesn't explain what ultrathink does. I'm confused about the differences between the Thinking Toggle On/Off feature and the old "think," "think harder," and "ultrathink" modes. There's also mention of MAX_THINKING_TOKENS and a legend around the 31,999 value, but it's unclear what these mean.

From what I've gathered, ultrathink toggles Thinking mode on for a single prompt? I'm not sure about that one, too.

With v2:

1. You can no longer adjust the Thinking budget or reasoning effort.
2. Ultrathink no longer performs "ultrathinking"—it's just a cosmetic remnant from the past.
3. MAX_THINKING_TOKENS 🤷

Suggested Improvement

Please improve docs around those things.
