Kai's verdictA-tier. S-tier if you self-host. The reason open-source image gen matters.S-tier for reasoning and writing. If you only pay for one chatbot, pay for this one — especially for long work.A-tier. The most interesting spreadsheet in years. Great for ops dashboards.B-tier standalone, A-tier value if you already pay ChatGPT. Don't pay for it separately.
