Kai's verdictS-tier for open-source model APIs. The default in this space.S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.B-tier. Still early. Manus is more flexible for less money.S-tier for ad-hoc analysis. Makes you feel like a data scientist in 30 seconds.
