Kai's verdictA-tier for data teams. S-tier if you already live in SQL + Python.S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.S-tier for reasoning and writing. If you only pay for one chatbot, pay for this one — especially for long work.S-tier for coding. If you write code of any kind, this pays back the $20 in a day.
