Kai's verdictA-tier for creators training custom looks. B-tier for general use.S-tier for reasoning and writing. If you only pay for one chatbot, pay for this one — especially for long work.A-tier. The Deep Research feature is genuinely useful. Don't sleep on it if you're already paying Google.A-tier. The most interesting spreadsheet in years. Great for ops dashboards.
