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.B-tier standalone, A-tier value if you already pay ChatGPT. Don't pay for it separately.A-tier. Rising fast. If you can tolerate the UX, quality per dollar is best-in-class.
