Kai's verdictS-tier for open-source model APIs. The default in this space.S-tier for reasoning and writing. If you only pay for one chatbot, pay for this one — especially for long work.S-tier for designers. The only one that takes vectors seriously.A-tier. The most interesting spreadsheet in years. Great for ops dashboards.
