Google put its "Deep Think" reasoning mode into Gemini for paying users
What it actually means
This is the first time Google's slow, show-its-working reasoning mode is something you can switch on rather than read about, but only on the top Ultra tier in the app, not in your code and not for free. Treat it as a tool for the hard, occasional problem, not your default. Worth pasting one genuinely gnarly task in this week to see if the extra thinking earns the wait and the price; for everyday work it won't. The capability is real, the access is narrow.
The capability is real; the access is narrow. Save it for the problem that's actually hard.
