Kai's verdictS-tier for reasoning and writing. If you only pay for one chatbot, pay for this one — especially for long work.B-tier. Still early. Manus is more flexible for less money.S-tier for speed. When latency is the product, start here.S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.
