Kai's verdictS-tier. If you're on Vercel/shadcn, this is cheating.S-tier for model-shopping. I use this for every prototype before committing.B-tier standalone, A-tier value if you already pay ChatGPT. Don't pay for it separately.A-tier. The most interesting spreadsheet in years. Great for ops dashboards.
