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 standalone, A-tier value if you already pay ChatGPT. Don't pay for it separately.S-tier for model-shopping. I use this for every prototype before committing.A-tier. The most interesting spreadsheet in years. Great for ops dashboards.
