Kai's verdictA-tier. The most interesting spreadsheet in years. Great for ops dashboards.A-tier for the right use case. Not for solo devs. If you manage engineers, try one license.S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.S-tier for reasoning and writing. If you only pay for one chatbot, pay for this one — especially for long work.
