Kai's verdictS-tier for model-shopping. I use this for every prototype before committing.A-tier. The most interesting spreadsheet in years. Great for ops dashboards.A-tier. Amazing when it works, frustrating when it doesn't. Runway still more reliable for pros.S-tier for reasoning and writing. If you only pay for one chatbot, pay for this one — especially for long work.
